Introduction to SeriesForewordAbstractChapter I: Project overviewAccording to uniform requirements of Monitoring Scheme for Siberian Cranes and Other Waterbirds of International Importance on Siberian Crane’s Flyway in China (“Monitoring Scheme”) developed by Siberian Crane GEF China Project Office, from 2004 autumn -2009 spring, survey teams conducted the migration monitoring of Siberian cranes and other waterbirds of international importance in Northeast China Hulunbeier Grassland, Northeast China Songliao Plain, Bohai Rim plain, and Yangtze River middle and lower floodplains in autumn and spring each year when cranes and storks migrate and settle.The entire monitoring project lasted 5 years, with 210 survey days annually and surveyed a total of 82 stopover wetlands for cranes and storks on Siberian cranes’ flyway, with 396 monitoring points built. More than 250 persons, including leaders and employees of forestry bureaus, wildlife protection stations and nature reserves and other units in counties/cities concerned, participated in some of monitoring work in different years. Survey area involves 10 provinces (autonomous regions) and 82 counties (cities).In the autumns of 2004-2008, a total of 125 waterbird species were recorded, which belong to 8 orders and 19 families. The number of waterbird species recorded in those years vary from 75-96, with total quantity of waterbirds ranging between 289916-689856; in the springs of 2005-2009, a total of 110 waterbird species were recorded, which belong to 8 orders and 16 families (see Table ). A total of 69-81 waterbird species were recorded in those years, with total quantity of waterbirds ranging between 105371-292601.Among waterbirds recorded, Siberian cranes, flagship species defined in Monitoring Scheme, were recorded in each season of all monitoring years. A total of key monitoring species including Grus grus, Grus japonensis, Grus monacha, Grus vipio, Anthropoides virgo, Ciconia boyciana, Ciconia nigra, Otis tarda, Larus relicts were identified, and a total of 28 important monitoring species such as Podiceps grisegena, Egretta alba, Platalea leucorodia, Anser cygnoides, Anser albifrons, Cygnus cygnus, Cygnus columbianus, Anas acuta, Anas crecca, Anas formosa, Anas poecilorhyncha, Anas Penelope, Anas querquedula, Aythya baeri, Aix galericulata, Haematopus ostralegus, Limosa limosa and Larus saundersi were also detected.There are a total of 46 monitoring points which recorded Grus leucogeranus stopping over in the course of migration. Jilin Momoge, Baolawendu, Liaoning Wolong Lake and Huanzidong are relatively stable stopover sites for Grus leucogeranus in these 5 years, and they are also stopover sites with the largest number of Grus leucogeranus recorded in Northeast China over recent 2-3 years. On 13 October 2008, 1829 Grus leucogeranus were observed in Jilin Momoge; on 30 April 2009, 2616 Grus leucogeranus were found resting in Momoge. The said two figures are the maximum number of Grus leucogeranus recorded on Songliao Plain in autumn and spring over recent 5 years.In the course of monitoring, a total of 23 waterbird species including Grus leucogeranus, Grus japonensis, Ciconia boyciana, Anser cygnoides, Anser fabalis, Anas formosa, Anas falcata, Aythya ferina, Aythya baeri, Tringa erythropus, Numenius madagascariensis, Larus saundersi were found with their population size accounting for more than 1% of global total, and 43 wetlands of international importance were identified.Under the promotion and influence of project activities, some of countermeasures and suggestions on waterbird habitat preservation have been accepted by competent wildlife administration departments; the preservation and restoration projects of Jilin Momoge, Xianghai, Liaoning Shuangtaihekou, Inner Mongolia Keerqin and other national nature reserves and cranes & storks stopover sites, and waterbirds gathering wetlands have been established at relevant provincial or national departments, and been funded by various levels of financial budgets; during the promotion of Liaoning Wolong Lake and Jilin Boluo Lake nature reserves from provincial level to national level, the results of waterbird monitoring projects become a major technical support; the establishment of nature reserves and preservation zones like Jilin Da’an alongshore wetland, Tongyu Shuanggang, Liaoning Huanzidong are direct outcome of monitoring activities. In addition, along with project activities, survey teams conducted public education on waterbirds and wetland preservation at survey areas, which has received good response.Without strong support and coordination from provincial and local governments, competent departments and nature reserves, the monitoring activities would not have been so successful.Section 1: Division of survey areaThe entire survey area is located in the east of China, and includes Hulunbeier Plateau, Songnen Plain, Lower Liaohe River Plain, Bohai Rim Alluvial Plain, and Middle and Lower Yangtze Valley Plain from north to south. It involves 11 provinces, municipalities and autonomous regions including Inner Mongolia, Heilongjiang, Jilin, Liaoning, Hebei, Tianjin, Shandong, Jiangsu, Anhui, Hubei and Hunan. With geographic coordinate of 110017/—128017/E, 29012/—51011/N, it crosses 18 degrees of longitude and stretches 1800Km from east to west; it crosses 21 degrees of latitude and stretches 2600Km from south to north. The whole area is an important flyway for waterbirds in East Asia.Section 2: Physical geography1) Songliao PlainThis region is a large sag basin developed since late Mesozoic Era, and Songliao depression area, located at the northern section of the second huge zone of subsidence in Xinhua system in terms of geologic structure. Its major geomorphological type is fluvial facies and alluvial facies in plain terrain, and the land is generally low-lying and flat. The mean sea level is 100—180m, and there are hilly areas and dunes scattered at some places. The sea level is less than 10m around Shuangtaihekou in the south of the region, and the sea level is even lower at offshore areas.It has rich water resources with permanent rivers like Songhua River, Nenjiang River and Liaohe River, and some inland rivers without estuaries such as Wuyuer River and Huolin River in the north of this region. With smooth topography and small gradient, the region is home to many scattered lakes and marshes. The maximum water depth of marsh is 75cm. The average pH value is 7, and the water is slightly alkaline. At low-lying places, seasonal marshes are formed due to natural precipitation, and those are main stopover sites for migratory East Asian cranes.With distinct continental monsoon climate, the annual active accumulated temperature (≥10℃) is 2100—2800℃. With little snow in cold winter and much rain in warm summer, the annual precipitation is 350—500mm. There is sharp temperature difference and little precipitation in spring and autumn. Subject to cyclone, heavy winds and hot spells often occur. Soil evaporation is high, generally 2—3 times precipitation and sometimes 9—10 times precipitation. However, Liaodong Bay in the south of Songliao Plain has a warm climate and is humid climate transitional zone. The annual active accumulated temperature (≥10℃) is about 3200—3500℃, and the average precipitation is 500—750mm.The soil falls into six types, namely, chernozem, meadow soil, alkali soil, saline soil, bog soil and sand soil, and chernozem, meadow soil and bog soil make up the bulk.The zonal vegetation is deciduous broadleaved forest, but woody plants are scarce owing to topography, climate and especially long-term human activities. The leading vegetation type is intrazonal reed marshes, mainly distributed at Zhalong and Lindian in Heilongjiang, Zhenlai, Tongyu and Da’an counties in Jilin and Panjin in Liaoning. Leymus chinensis meadow steppes appear at high topography. At the transitional zones between reed marshes and Leymus chinensis meadow steppes, discontinuous alkaline meadows are often found due to changes in topography, soil and moisture.2) Bohai RimBohai Rim is a representative region with an almost complete set of coastal wetland types, with low topography and little undulation, and it is home to compound coastal wetlands composed of rivers, shallows, ditches, marshes, waterlogged depressions and salt fields formed under the combined influence of dynamic forces of rivers and seas and human activities. Hengshui Lake, located at the central south of North China Plain, is a stretch of depressions formed in 602 BC, when the Yellow River burst and changed its course; Yellow River Delta wetland is a plain of deposition formed through continuous sedimentation of Yellow River mud and sand filling Bohai depressions, and the geomorphology mainly includes terrestrial, tidal-flat and subtidal geomorphology.Cangzhou-Tianjin coastal rivers belong to Haihe River water system, and relatively large rivers include Duliu, Jianhe, Ziyaxin river, Beipaishui river, Jiedijian river and Nanpaishui river. Large fresh lakes including Beidagang Reservoir, Nandagang Reservoir, and Yangcheng Reservoir in Haixing county, were formerly lagoons formed through river scouring and sea tide forcing, and then people built dams for floor control and water conservation. Besides Yellow River, Yellow River Delta wetland receives water from rivers like Xiaoqinghe River, rainfall and snowfall. The wetland is home to many reservoirs and lakes and numerous rivulets and channels as well as reed marshes and freshwater marshes in large areas.This region has a warm temperate semi-humid monsoon climate, and enjoys marine climatic characteristics for its proximity to Bohai Sea. It boasts four distinctive seasons: dry & windy spring, hot & rainy summer, temperate & clement autumn, and cold and little-snow winter. The annual mean temperature is 12.1℃, and the annual mean precipitation is 642.5mm.The vegetation is mostly halophyte and marsh herbaceous plants, and the dominant plant species include reed, Suaeda salsa Pall., Puccinellia, Setaria viridis (Linn.) Beauv., Myriophyllum verticillatum, Form potamogeton crispus, Potamogeton pusillus Linn. L, etc.3) Yangtze River middle and lower reachesMiddle and Lower Yangtze Valley Plain includes Dongting Lake, Poyang Lake and lakes in Wuhan in middle reaches, lakes along Yangtze River in Anhui in lower reaches, as well as Hongze Lake, Gaoyou Lake, Taihu Lake in southern Jiangsu. With low topography, less than 50m sea level at most places and interwoven networks of rivers & lakes, it is a major fresh lake district in China.Most lakes in the district are regulating and inflowing lakes, with aggregate water area of over 280,000 ha. The water level difference between a high flow period and a low water period is generally 8—18m. In summer or high flow period, the shallow water area of Dongting Lake is 12,400 ha. and the deep water area is 53,000 ha.; in winter or low water period, the shallow water area is 646,000 ha. and the deep water area is 19,400 ha.. The combined water area of all lakes under survey in Wuhan, including Chenhu Lake, Wanghu Lake and Liangzi Lake, is 70,000 ha., while the total area of lakes along Yangtze River in Anhui, such as Shengyu Lake, Wabu Lake, Longgan Lake and Caizi Lake is nearly 150,000 ha. The aggregate area of Hongze Lake and other lakes in southern Jiangsu exceeds 20,000 ha.This region enjoys subtropical humid monsoon climate and is characterized by plenty of heat and rain, long frost-free period and four distinctive seasons. The annual mean temperature is around 17℃, and the annual active accumulated temperature (≥10℃) is 5360¬—6234℃. The frost-free period is 266—273 days, and the annual rainfall is 1300—1400mm.Local soil comes from sedimentary deposits carried by Yangtze River and its branch rivers. Soil in lake basin and shallows falls into tidal soil, bog soil, swamp meadow soil and sandy soil according to different elevations. The soil is neutral and slightly acidic.Vegetation at and around lakes chiefly includes grass family, compositae, cyperaceae, polygonaceae, waterlily family, cattail family and salicaceae, and can be divided into lake vegetation and beach vegetation according to flooding status.Section 3: Monitoring pointsFrom 2004 autumn - 2009 spring, all monitoring regions established a total of 396 monitoring points in all 82 wetlands, including 73 points in Yangtze River middle and lower reaches monitoring region, 59 ones in North China monitoring region, 3483 in Liaoning & Jilin monitoring region, and 151 in Inner Mongolia & Heilongjiang monitoring region. Current deployment of monitoring points basically covers all known stopover sites for Siberian cranes’ flyway in eastern China.For more information on location and quantity of monitoring points in monitoring regions, refer to Appendix 1: monitoring point deployment and numbering.Figure: Schematic map for distribution of monitoring points and wetlandsProvincial administration centerBeijingProvincial boundaryWater areaMonitoring pointChapter III Monitoring Network and MethodSection 1: Monitoring networkI. Organization structureEstablishing a Grus leucogeranus monitoring network is organizational guarantee for project implementation. This monitoring network project involves National Project Office, national experts, coordinators for monitoring regions and survey teams of known and potential habitats.In accordance with relevant provisions of Siberian Crane GEF Project, National Project Office is responsible to review monitoring scheme, organize project implementation, supervise and manage the projects, inspect phased monitoring reports and prepare annual reports;National experts are fully responsible for guidance and coordination of monitoring project, quarterly reports on migration monitoring of Grus leucogeranus in China and writing annual reports;The project designates 1 region-specific coordinator for each monitoring region. The coordinator is responsible to organize and coordinate survey personnel to carry out their work, timely learn about and report problems existing in project implementation, summarize regional monitoring data and information on a quarterly basis, and submit phased monitoring reports to national experts and National Project Office;Survey team members consist of relevant personnel with nature reserves, competent wildlife, wetland and environmental authorities, colleges/universities, research institutes, local volunteers and villagers on Siberian cranes’ flyway, and such teams are responsible for specific tasks of monitoring points.II. Network compositionTo facilitate the implementation of monitoring work, the entire survey area is divided into 4 regions, namely middle and lower Yangtze River stopover region, North China stopover region, Northeast China Liaoning & Jilin stopover region, Northeast China Heilongjiang & Inner Mongolia stopover region. The five project points of China Siberian Crane GEF Project belong to relevant monitoring regions separately: Poyang Lake district is put under middle and lower Yangtze River region; Zhalong belongs to Heilongjiang-Inner Mongolia region; Xianghai, Momoge and Keerqin is managed by Liaoning-Jilin region.Section 2 Monitoring method1) Selection and establishment of monitoring pointsAt a wetland designated in Monitoring Scheme, choose 1 or more positions with high elevation, a shortest possible distance from the species under survey, and with broad view as monitoring points, using GPS.2) Monitoring surveyFixed-point statisticsHabitat survey: observe wetland type, dominant vegetation, human activities, weather conditions and other aspects of survey site with naked eye or 8x telescope.Species statistics: identify population structure and stopover behavior of and directly count the population size of key monitoring species in the range of vision with 40—60x telescope; for anatidae and shorebirds with a large population size, the grid counting method is adopted, where those birds are counted in the unit of 10, 50 or 100. The result of quantity statistics is the average value of statistical quantities by different persons or in different cases. The statistical time of each monitoring point shall meet the needs of species identification and counting, generally no less than 30 minutes.Monitoring record: on the date of survey completion, the Record Sheet for Fixed Point Survey of Cranes and Other Important Waterbirds shall be filled up according to unified reporting notes and requirements set out in the Monitoring Scheme, subject to discussion and agreement by all survey personnel.Interview surveyFor information that cannot be obtained directly from fixed point statistics, the survey is conducted through interviewing relevant personnel. The survey results are filled into a uniform Interview Survey Record Sheet.Migration rules monitoringAt 4 Northeast China points under Siberian Crane GEF Project, which are major stopover sites for Grus leucogeranus, strengthen migration monitoring frequency and intensity, and accurately obtain the date of first appearance, peak period and date of last appearance for Grus leucogeranus migration at all project points; during the unified monitoring period stipulated for the project, a comprehensive waterbirds synchronous survey shall be carried out.Location monitoring:At Mount Lianfeng in Beidaihe, observe and record migrating cranes and storks and other birds non-stop every day for 30 working days in spring and autumn each.3) Data statistics(1) The addition of direct-counting results of one or more monitoring points at the same wetland (water body, river, marsh, etc.) over the same period of time is the quantity of waterbirds in the wetland;(2) Generally speaking, take the maximum value of several direct-counting results for one monitoring point at the same wetland (water body, river, marsh, etc.);(3) For the same wetland (water body, river, marsh, etc.) with both wintering and migrating population, the migrating data for North China region is included in the statistics, while the wintering data is stated in the “remarks” part of the report; the migrating data for middle and lower Yangtze River region is included in the statistics, and the wintering data is stated in the report;(4) Data from interview surveys is not included in statistics, but shall be explained in the remarks.(5) Monitoring data for Mount Lianfeng at Beidaihe is not included in region-specific statistics, but shall be contained in a separate report.4) Information summary and reportRelevant data and information shall be summarized and reported in the ascending order of monitoring point responsible person, survey area coordinator and chief technology responsible person. The format and content of phased result reports is stipulated in the Monitoring Scheme.Section 3: Monitoring content and timeI. Monitoring speciesDivision of monitoring speciesMonitoring species fall into three types, i.e., flagship and key monitoring species, important monitoring species, and other monitoring species.Flagship species: Grus leucogeranus (1 species);Key monitoring species include 10 species living on the same habitat as Grus leucogeranus, namely, Grus japonensis, Grus vipio, Grus grus, Grus monacha, Anthropoides virgo, Grus canadensis, Ciconia boyciana, Ciconia nigra, Larus relicts, and Otis tarda;Important monitoring species refer to 37 migratory waterbirds of international importance, mainly including “waterbirds” defined in Conventions on Wetlands, Appendixes I-III to Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES), China’s Catalogue of Wild Animals under Key National Protection as well as Catalogue of Waterbirds Wintering in Asia.Other monitoring species refer to other waterbird species identified in surveys.II. Monitoring content(I) Flagship and key monitoring species(1) Distribution, quantity and population structure, including population size, subfamily quantity, adult-young ratio, etc.;(2) Stopover conditions, including landform, water level, wetland vegetation types, etc.;(3) Main threats to cranes & storks migration destinations and protection measures taken;(4) For 5 Siberian Crane GEF Project points, monitor the time of inbound migration (first appearance), time of outbound migration (last appearance), migration peak, wintering peak and settlement period of cranes and storks, especially Grus leucogeranus.(II) Important monitoring speciesRecord the types, distribution and quantity of important monitoring species, and give necessary attention to population trends (especially habitats for cranes and storks).(III) Other monitoring speciesObserve types, distribution and quantity status.(IV) Waterbirds with more than 1% of global population size and wetlands of international importanceAdopt the latest standard of waterbirds accounting for 1% of global population size released in 2006, record and make statistics on the species of waterbirds whose quantity exceeds 1% of global population size and their habitats (including habitats for waterbirds with population size of more than 20,000), and highlight wetlands of international importance where 1 or more waterbird species with more than 1% of global population size (waterbirds with population size of more than 20,000) gather.III. Monitoring timeAnnual arrangement:Heilongjiang-Inner Mongolia, Liaoning-Jilin, North China regions: 2004 autumn—2009 springMiddle and lower Yangtze River region: 2004 autumn—2006 springSeasonal arrangement: conduct one survey at stopover region in autumn and spring each;Date arrangement: choose the period when Grus leucogeranus migrate steadily.Northeast China stopover region: autumn: mid-to-last ten days of September-last ten days of OctoberSpring: last ten days of March -mid-to-last ten days of MayNorth China stopover region: autumn: last ten days of October -first ten days of NovemberSpring: first-to-mid ten days of MarchMiddle and lower Yangtze River stopover region: winter: last ten days of December-first ten days of January.SchedulingAccording to Grus leucogeranus migration sequence, choose the periods when stopover Grus leucogeranus population remains stable and determine the best monitoring time for all monitoring regions.During monitoring periods, adopt different methods such as continuous observation, intermittent observation, each monitoring with a hiatus of 5 days and 24-hour monitoring for a certain period according to Grus leucogeranus migration calendar and monitoring tasks for different regions.The monitoring progress of survey teams at different monitoring regions shall be basically well connected according to Grus leucogeranus migration sequence without noticeable hiatus.Chapter III Monitoring ResultsSection 1 Autumn monitoring1.1 Overview of migratory waterbirdsSpecies and quantityIn the autumns of 2004-2008, a total of 125 waterbird species are monitored, which belong to 8 orders and 19 families. A total of 75-96 waterbird species and 289916-689856 waterbirds are recorded annually, including 49-84 species and 78711-259157 waterbirds in Heilongjiang - Inner Mongolia monitoring region; 40-61 species and 32164-285069 waterbirds in Liaoning - Jilin monitoring region; 58-73 species and 53778-107181 waterbirds in North China monitoring region; 47-57 species and 110697-133092 waterbirds in middle and lower Yangtze River monitoring region.For waterbird species and quantity recorded in monitoring regions in different years, refer to the following table:Statistics of waterbird species and quantity in 2004-2008 autumnsTotal Heilongjiang-Inner Mongolia Liaoning-Jilin North China Yangtze River2004waterbird quantity 179219 78711 32164 68344 110697number of species 75 49 40 65 572005waterbird quantity 550474 278526 196305 75643 133092number of species 96 75 60 61 472006waterbird quantity 598004 259157 285069 53778number of species 96 84 61 642007waterbird quantity 513971 240817 190080 83074number of species 95 79 58 732008waterbird quantity 689856 358672 224003 107181number of species 86 68 56 58Compare the quantity of waterbirds recorded 3 regions (i.e., Heilongjiang-Inner Mongolia, Liaoning-Jilin and North China) in autumns of 2004-2008, and we find the quantities are generally on the rise. Especially during 2004-2005 autumns, waterbird quantity triples from 179219 to 550474. In the autumns of the following 3 years, the quantity of waterbirds on eastern China Siberian cranes’ flyway remains approximately 600,000.Composition of migratory populationsMost of migratory waterbirds are anatidae and shorebirds, totaling 59 species, making up 47.2%, almost half of all waterbird species identified. There are 33 species of anatidae, making up 26.4% of all species recorded; 26 species of shorebirds (20.8%); followed by 15 species of gulls and 12 species of herons, which account for 12.0% and 9.6% of all waterbird species monitored respectively. The families with the fewest number of species include Pelecanidae, Threskiorothidae, Jacanidae, Haematopodidae, Phalaropodidae, Glareolidae and Alcedinidae, each of which has only 1 species. The composition characteristic of the migratory group differs little in different monitoring regions.Dominant species and rare speciesIn the autumns of the consecutive 5 years, the total number of top 10 waterbird species with largest size of migratory population size is 1408935, accounting for 50.8% of 2775313, total number of migratory waterbirds recorded. These are dominant species of migratory waterbirds in autumn. They are:1 Anser fabalis 3876052 Anas platyrhynchos 2341003 Anas strepera 1683154 Anas poecilorhyncha 1359765 Anser albifrons 1011126 Aythya ferina 834167 Larus ridibundus 784628 Anas crecca 767419 Anser anser 7631710 Fulico atra 66891The migratory species with smallest population size and the quantity of waterbirds recorded being 1-3 are shown below:1 Limnodromus semipalmatus 32 Gallinago hardwickii 33 Calidris canutus 34 Egretta eulophotes 25 Hydrophasianus chirurgus 26 Butorides striatus 17 Anser indicus 18 Rallus aquaticus 19 Amaurornis akool 110 Charadrius placidus 111 Arenaria interpres 11.2 Flagship species1) DistributionDistribution characteristicsIn autumn, Grus leucogeranus migrate from breeding places in Russia to China, chiefly during the trip to Jiangxi Poyang Lake wintering places, and choose some wetlands in Northeast China Songnen Plain, North China Bohai Rim shores, and Yangtze River middle and lower reaches as stopover sites during their migration journey. In the autumns of 2004-2008, Grus leucogeranus are found in 43 stopover sites (see Table --), including 6 ones in Heilongjiang-Inner Mongolia monitoring region; 20 ones in Liaoning-Jilin monitoring region; 10 ones in North China monitoring region; 7 ones in middle and lower Yangtze River monitoring region.BeijingProvincial administration centerProvincial boundaryWater areaFigure 4 Schematic map for Grus leucogeranus stopover sitesAs shown in distribution pattern of Grus leucogeranus stopover sites, the north of Northeast China Songnen Plain, a centralized area involving eastern Inner Mongolia, southwestern Heilongjiang, and western Jilin with many autumn stopover sites, is home to 24 stopover sites, making up 55.8% of total number of Grus leucogeranus autumn stopover sites in eastern China. The total area of this centralized part is about 234,000km2.Although there are 43 Grus leucogeranus stopover sites in eastern China, only 15-27 sites are utilized annually. In 2007 autumn, 17 stopover sites are visited by Grus leucogeranus, which is the lowest utilization rate in autumns of the 5 years. In any of the other years, there are more than 20 stopover sites. There are 27 stopover sites in 2004 and 2006 each, and they are the years with the biggest number of autumn stopover sites in recent 5 years.Annual statistics of Grus leucogeranus stopover sites (2004-2008 autumns)Year Total Inner Mongolia Heilongjiang Jilin Liaoning Hebei Tianjin Shandong Anhui Jiangsu Hunan Hubei2004 27 2 4 12 1 1 1 3 1 1 12005 24 4 5 8 1 2 2 22006 27 5 3 11 1 5 22007 15 1 9 2 1 22008 22 3 2 10 3 3 1HabitatIn their autumn migration, Grus leucogeranus select Leymus chinensis meadow, alkaline meadow, reed marsh, coastal shoals, lake beaches, grass islands and other wetlands as stopover sites. Due to natural and geographic conditions in southern and northern China, there are different foods available for Grus leucogeranus and the most suitable living conditions for their stopover sites also differ.There are 19 wetlands for Grus leucogeranus stopover on Northeast China Songliao Plain and North China coastal alluvial plain, including 10 alkaline meadow wetlands and 9 reed marsh wetlands, and alkaline meadow wetlands are slightly dominant. Except the fact that water log at alkaline meadows almost dries up due to recent years’ consecutive drought, Northeast China, the characteristic of Grus leucogeranus choosing alkaline meadows as the most suitable habitat will become more distinct. Alkaline meadows are widely distributed in alkaline lowlands, dales, lake rims and river shoals in northern China. Due to rigorous habitat conditions, vegetation types are scarce, and dominant vegetations include Suaeda glauca, S.heteroptera and S.corniculata. Some plants like Scirpus planiculmis have deep root systems which develop into thick tubers, providing major foods for Grus leucogeranus on Northeast China stopover sites.Compared with Grus japonensis and Grus vipio, even if Grus leucogeranus select reed marshes for their stopovers, they only stay on the edges of reed marshes, where there are sparse plants and shallow water log, usually distributed with alkaline meadows and Leymus chinensis meadows nearby.Along Yangtze River middle and lower reaches, 5 stopover sites for Grus leucogeranus are all grass islands along lakes. In summer, submerged plants in lakes feature Form potamogeton malainus) community, Form potamogeton crispus, Vallisneris gigantean, Najas spp communities. With simple species combination, the plant communities are sometimes single-species community and sometimes associated plant communities. With broad distribution and large area, Form potamogeton malainus community contains rich aquatic plant resources, and usually becomes habitats for various kinds of shrimps and breeding grounds for fishes laying adhesive eggs. In autumn and winter, lake water recedes and shallows or lake beaches emerge, thus becoming the most suitable habitat for Grus leucogeranus to stay and winter. The tubers of Form potamogeton malainus and Vallisneris gigantean, fish and shrimps provide food for Grus leucogeranus.Apart from basic natural and geographic conditions, stopover selection of Grus leucogeranus is also related to interference intensity. Compared with other wetlands, at 31 migration stopover sites recorded in the autumn of 2004, human activities like fishing, grazing and farming are relatively infrequent, which brings little direct disturbance to Grus leucogeranus and forms a relatively quiet environment. For chosen stopover sites, without major change to habitat, Grus leucogeranus tend to choose the same site as their “post” during their migration journey year by year, or we may call it “tradition” of stopover site selection. For instance, Halata alkaline meadow in Momoge Nature Reserve has been chosen for Grus leucogeranus stopover site in spring and autumn migration for 15 straight years. Caizi Lake wetland in Anhui along Yangtze River has been visited by Grus leucogeranus for recent 3 years. At “traditional” stopover sites, Grus leucogeranus have much higher resistance to human interference than temporary stopover sites. Over recent years, due to water shortage in some Northeast China wetlands, water log in meadows dries up and many traditional stopover sites are discarded, including Tongfa grazing land along Huolin River in Jilin Tongyu, Baomin in the northwest of Zhenlai, Chatai in the center of Zhenlai, and Sanmianchuan in Liaoning.Utilization of stopover sitesEvaluate Grus leucogeranus autumn stopover sites with annual utilization frequency of stopover site as stability index, and we get the following result:Grus leucogeranus stopover sites and utilization frequency over 04-08 autumnsprovince wetland 2004 2005 2006 2007 2008 frequency1 Inner Mongolia Wulannuoer √ 20%2 Inner Mongolia Argun River √ 20%3 Inner Mongolia Tumuji Nature Reserve √ √ √ 60%4 Heilongjiang Zhalong Nature Reserve √ √ √ 60%5 Heilongjiang Daqing wetland √ 20%6 Heilongjiang Tailai wetland √ √ 40%7 Jilin Zhenlai Baiyintaohai √ √ √ 60%8 Jilin Zhenlai Xiaowulantu √ √ 40%9 Jilin Zhenlai Chuangye √ 20%10 Jilin Zhenlai Red Flag horse farm √ 20%11 Jilin Momoge √ √ √ √ 80%12 Jilin Taonan Erlong √ 20%13 Jilin Xianghai √ √ √ 60%14 Jilin Baolawendu √ √ √ √ √ 100%15 Jilin Tongyu Shihuadao √ 20%16 Jilin Da’an Dagan √ 20%17 Jilin Qian’an Shuzi √ 20%18 Jilin Changling Santuan √ 20%19 Jilin Changling No. 3 √ 20%20 Jilin Qianguo Wulan’aodu √ 20%21 Jilin Chagan Lake √ 20%22 Jilin Boluo Lake √ √ √ 60%23 Jilin Shuangliao Sanhetun √ √ √ 60%24 Liaoning Wolong Lake √ √ √ 60%25 Liaoning Huanzidong √ √ √ 60%26 Liaoning Dalinghe River √ 20%27 Hebei Beidaihe Xinkaihekou √ 20%28 Hebei Funing County Yanghekou √ 20%29 Hebei Changli Tuanlin Qilihai √ √ √ 60%30 Hebei Changli Tuanlin Xinlizhuang √ 20%31 Hebei Changli Luanhekou Dongtan √ 20%32 Hebei Nandagang wetland √ √ 40%33 Hebei Haixing Qingxian salt field √ 20%34 Shandong Yellow River Estuary wetland √ √ 40%35 Shandong No.121 coastal shoal √ √ 40%36 Shandong Dawenliu √ √ √ √ 80%37 Jiangsu Douhu Lake √38 Anhui Shengjin Lake (3,000mu/combined) √39 Anhui Caizi Lake (Dongfeng Wei) √ √40 Anhui Shimen Lake √41 Hubei Yidu (Wangjiafan) √42 Hubei Wanghu Lake (Xiayang Lake/500mu) √43 Hunan East Dongting Lake Chunfengyuan √In the autumns of 5 years, the wetland used by Grus leucogeranus as their stopover is Jilin Baolawendu, with 100% utilization frequency, and it is the most stable stopover site for Grus leucogeranus in autumn; Jilin Momoge and Shandong Yellow River Delta Dawenliu are selected by Grus leucogeranus as their stopover sites with 80% utilization frequency, and they are used in autumn of 4 years; there are 9 stopover sites with 60% utilization frequency, namely, Inner Mongolia Tumuji, Heilongjiang Zhalong, Jilin Xianghai, Chagan Lake, Boluo Lake, Shuangliao Sanhetun, Liaoning Wolong Lake, Huanzidong, and Hebei Changli Tuanlin Qilihai; there are a great number of other stopover sites, but they are visited Grus leucogeranus in 1 or 2 years over 5-year survey. They are just randomly chosen. The habitats are relatively fragile and easily discarded due to strong outside interference.2) QuantityQuantity statusIn autumns of 2004-2008, the number of Grus leucogeranus recorded annually is 761-3032, including 146-447 in Inner Mongolia - Heilongjiang monitoring region, 211-2808 in Liaoning - Jilin monitoring region, 45-480 in North China monitoring region, and 38-39 in middle and lower Yangtze River monitoring region. Liaoning-Jilin region is home to the largest number of Grus leucogeranus. In 2008 autumn, its highest quantity accounts for 92.6% of the highest quantity in eastern China. North China, and especially middle and lower Yangtze River regions are rarely visited by Grus leucogeranus. The recorded quantity makes up about 5.0% of annual total quantity (2005 autumn).Population size of Grus leucogeranus over autumns of 2004-2008year Subtotal Heilongjiang-Inner Mongolia Liaoning-Jilin North China Yangtze River middle and lower reachesregion Inner Mongolia Heilongjiang region Jilin Liaoning region Hebei Shandong region Anhui Jiangsu Hunan Hubei2004 761 447 360 87 211 116 95 65 2 63 38 31 3 3 12005 599 363 125 238 152 148 4 45 45 39 6 332006 2006 299 191 108 1227 1047 180 480 394 862007 2000 1 1 1922 1726 196 77 31 462008 3032 146 98 48 2808 2145 663 78 53 25Total 8398 1256 775 481 6320 5182 1138 745 480 265 77 37 3 3 34In autumns of 5 years, the quantity of Grus leucogeranus recorded is on the rise, and the number increases sharply in autumn of 2006 and 2008 respectively. The number recorded in 2005 autumn rises significantly (about 3.3 times) from 599 in 2005 autumn to 2006 in the autumn of 2006; the number recorded in 2008 autumn is 3032, more than 1.5 times that in 2007 autumn.Maximum stopover populationThe annual maximum stopover populations are recorded in Inner Mongolia Tumuji, Heilongjiang Zhalong, Jilin Baiyintaohai and Jilin Momoge respectively. The quantity of Grus leucogeranus recorded in Momoge Reserve in the autumns of 2007 and 2008 exceeds 1500, accounting for over 50% of global population size.Site and quantity of maximum stopover population in autumns of 2004-2008year maximum stopover populationsite quantity2004 Inner Mongolia Tumuji 3202005 Heilongjiang Zhalong 1402006 Jilin Baiyintaohai 8502007 Jilin Momoge 15032008 Jilin Momoge 1829Consistent with the change trend of stopover quantity over autumns of 5 years in eastern China, the quantity of annual maximum stopover population is also on the rise. In 2006 autumn, Grus leucogeranus gather in big numbers. 850 are identified in Jilin Zhenlai Baiyintaohai; in the following 2 years, this gathering phenomenon becomes more noticeable and they stop over in Jilin Momoge.3) Population structureThrough population statistics of identifiable young cranes, the quantity of young cranes and the ratio of young cranes to the whole group recorded in autumns of different years are shown in Table 5.1-8.Table 7: Population structure of Grus leucogeranus in autumnyear Liaoning-Jilin North China Yangtze River middle and lower reachespopulationquantity young-cranequantity young-craneratio populationquantity young-cranequantity young-craneratio populationquantity young-cranequantity young-craneratio2004 204 29 0.14 65 21 0.32 35 6 0.172005 52 11 0.21 45 14 0.31 39 4 0.102006 377 40 0.11 480 31 0.062007 223 33 0.152008 2145 240 0.11 78 2 0.03In autumn, the ratio of young cranes to the entire population is 10-30%, with 14.4% for Liaoning-Jilin region, 18.0% for North China, and 14.0% for middle and lower Yangtze River region. The bigger population size, the closer adult-young ratio is to actual data. The number of group quantity recorded in Liaoning-Jilin in 2005 autumn is only 52, and adult-young ratio is 21.2%, much higher than actual value. This is also the case with the statistics of North China in 2004, 2005 autumns. The quantity of group size is 45-65, and the ratio of young cranes to entire group is 31-33%. In other years, the number of population size recorded is more than 200 and the statistical result of young crane ratio is 10-14%, which shows the actual population structure to some degree. In 2008 autumn, the number of stopover Grus leucogeranus in Momoge is 1829 and it is the ideal place for statistics on Grus leucogeranus population structure. Among 1747 cranes, 195 young ones are identified, and the ratio of young cranes to the entire population is 11.2%, which shall be the value closest to actual data.4) Migration trendsAccording to limited information on Grus leucogeranus migration trends, 迁到Grus leucogeranus first appear in Northeast China Songnen Plain generally in mid-to-last ten days of September in autumn; from then to mid-to-last ten days of October, the stopover quantity reaches the peak, and keeps a high level to last ten days of October with slight change; by the end of October, some cranes leave and the stopover population size fall. With several quantity fluctuations, no Grus leucogeranus stays at first-to-mid ten days of November. The Grus leucogeranus autumn migration lasts 50-60 days;In Bohai Rim wetland, the duration of Grus leucogeranus autumn stopover is remarkably shortened. According to the result of Yellow River Delta Dawenliu wetland monitoring, the date of first appearance of Grus leucogeranus falls within mid-to-last ten days of October and the number reaches the peak at the beginning of November. They start to leave at the middle ten days of November, and the migration lasts about 20 days;For Yangtze River middle and lower reaches (excluding Jiangxi Poyang Lake), inbound migrating Grus leucogeranus are observed on October 28, and Grus leucogeranus are first found at other sites mostly during November 1—5. To be precise, migration stopover sites are mostly Hubei Wanghu Lake, Anhui wetlands along Yangtze River and Shengjin Lake. The quantity recorded in those areas in autumn is noticeably different from wintering quantity, and a small proportion of the species shall winter there. The majority of them continue to migrate southward, and such migration lasts about 20 days in Hubei.Momoge Reserve is strategically important for Grus leucogeranus migration in Northeast China Songnen Plain. In autumns of 2006-2008, the stopover period of migrating Grus leucogeranus lasts 50-60 days, and stopover quantity of 860-2035. It offers ideal conditions for observing Grus leucogeranus migration trends, and the monitoring results are quite typical and representative.The changes on stopover quantity of Grus leucogeranus during migration in Momoge in 2006-2008 autumn display the three dynamic change periods, namely, rising quantity, relatively stable and falling quantity. Although Grus leucogeranus migrate there very early in 2008 autumn, the population size maintains a low level of 18-43 until the end of September. By September 30, just like in 2006 and 2007 autumn, the quantity of stopover Grus leucogeranus in the Reserve rises sharply and keeps the momentum until the middle ten days of October. This period lasts about 15 days. The following 10 days is a period of relative stability with high quantity of stopover Grus leucogeranus. During this period, the annual peak value of inbound migrating Grus leucogeranus often appears. Generally speaking, the period of declining stopover quantity starts from October 25 until the date when all Grus leucogeranus leave. Like rising quantity period, the falling quantity period also lasts about 15 days. During this falling quantity period, stopover quantity of Grus leucogeranus fluctuates 2-3 times at the end of October and each fluctuation will cause a big decrease in the stopover quantity. In the end, Grus leucogeranus leave thoroughly. Hundreds of them tend to fly away in no time.Table 5.1-8: Date and quantity of stopover Grus leucogeranus in Momoge in 2006-2008 autumns2006 Date 10.1 10.2 10.3 10.8 10.14 10.16 10.23 11.1 11.2Qty. 0 6 5 76 860 51 172 166 02007 Date 9.30 10.1 10.9 10.12 10.14 10.17 10.19 10.21 10.23 10.25 10.27 10.29 10.31Qty. 0 7 482 956 1035 1382 1327 1305 1485 1111 1282 857 5172008 Date 9.2 9.3 9.5 9.8 9.11 9.16 9.19 9.25 9.30 10.5 10.6 10.8 10.9Qty. 0 18 30 26 29 21 40 43 85 173 678 439 8772007 Date 11.1 11.2 11.3 11.4Qty. 521 262 644 02008 Date 10.11 10.12 10.13 10.15 10.17 10.19 10.23 10.24 10.25 10.26 10.28 10.29 10.30Qty. 1410 1451 1856 2035 1753 1743 1582 1724 1659 6 745 1496 14472008 Date 11.1 11.3 11.6 11.7 11.8Qty. 360 352 332 36 01.3 Key species - other cranes and storks1) Grus grusDistributionOn eastern China Siberian cranes’ flyway, the range of Grus grus distribution is limited.

Their population observed during survey is generally large. In 2007, Jilin Boluo Lake records a stopover population of 550. In 2004, Liaoning Linghai records a group of 506 birds. These two wetlands witness two largest stopover populations over 5 years. In the 1980-90s, Momoge Reserve used to be the biggest gathering place for Ciconia boyciana before southward migration in autumn in East Asia. It once recorded a stopover population of 300-800. Due to large influence to the gathering environment over recent 10 years, Ciconia boyciana gathering place no longer exists and they have to choose another place. This might be the reason for frequent change of stopover sites with the largest population of Ciconia boyciana recorded during survey.Site and size of largest Ciconia boyciana stopover populations in 2004-2008 autumnsYear Site Qty.2004 Liaoning Linghai Dayou Farm 5062005 Momoge Reserve 2002006 Liaoning Linghekou Reserve 2362007 Jilin Boluo Lake Reserve 5502008 Xianghai Reserve 2107) Ciconia nigraDistributionIt is a species rarely found during survey.

The quantity of waterbirds is on the rise from 2005 spring - 2007 spring. But in 2008 spring, waterbird quantity falls 48.4% from 292610 in 2007 spring to 150891.This change might be related to rain and snow disaster that hit Yangtze River middle and lower reaches in 2007 winter. In the spring of 2009, the quantity of waterbirds returned to a high level over 5 springs. Over 3 springs, the quantity of waterbirds on Siberian cranes’ flyway in eastern China remains around 250,000, well below the quantity of 600,000 recorded in autumn.2) Composition of migration populationsMigratory waterbirds feature anatidae and shorebirds, totaling 58 species or accounting for 52.7% of total number of waterbird species recorded. There are 31 anatidae species and 27 shorebird species. There are 14 species of gulls and 10 species of herons, accounting for 12.7% and 9.1% of all waterbird species surveyed. The following families with only one species recorded each: Pelecanidae, Phalacrocoracidae, Otididae, Haematopodidae, Recurvirostridae, Glareolidae and Alcedinidae. This composition characteristic of migration populations varies little in different monitoring regions. It is also consistent with composition of waterbird population in autumn.3) Dominant species and rare speciesIn 5 springs, the total number of top 10 waterbird species in terms of population size is 743699. They are dominant species in spring migration, accounting for 56.5% of 1317000, total number of migratory waterbirds.

Flagship species - Grus leucogeranus1) DistributionLocation and quantity of stopover sitesIn 2005-2009 springs, a total of 28 stopover sites record Grus leucogeranus (refer to table --), including 5 ones in Inner Mongolia, Heilongjiang monitoring region; 14 in Liaoning, Jilin monitoring region; 7 in North China monitoring region; 2 in middle and lower Yangtze River monitoring region.The number of Grus leucogeranus stopover sites used annually is 15-23. The spring of 2009 records only 15 Grus leucogeranus stopover sites, the lowest utilization rate in 5 autumns. In any other year, the number of stopover sites is about 20. There are 23 stopover sites in 2006, the highest utilization rate over 5 springs.For annual statistics on Grus leucogeranus stopover sites and quantity in spring, refer to the table below:Statistics on Grus leucogeranus stopover sites in 2005-2009 springsHeilongjiang-Inner Mongolia Liaoning-Jilin North China Middle and lower Yangtze RiverRegion Inner Mongolia Heilongjiang Region Jilin Liaoning Region Hebei Shandong Region Anhui2005 20 12 4 8 6 3 3 1 1 1 12006 23 7 2 5 14 11 3 1 1 1 12007 19 5 3 2 10 5 5 4 3 12008 19 5 3 2 13 10 3 1 12009 15 4 2 2 9 5 4 2 1 1Grus leucogeranusBeijingProvincial administration centerProvincial boundaryWater areaFigure 4: Schematic map for Grus leucogeranus stopover sites2) Stopover habitatsLike in autumn, Grus leucogeranus choose Leymus chinensis meadow, reed marsh, coastal shoals, lake beach, grass islands and other wetlands as their stopover sites in spring migration. However, due to winter transpiration, water log in alkaline meadows on Northeast China Songnen Plain almost dries up in spring. As a result, Grus leucogeranus cannot use those places, but chooses to stop over at the rims of reed marshes instead. There are sparse plants and shallow waters, which are mixed with nearby alkaline meadows and Leymus chinensis meadows.Over recent 2-3 springs, Grus leucogeranus gather in large groups at 3 wetlands including Liaoning Wolong Lake, Huanzidong and Jilin Momoge. Wolong Lake and Huanzidong have limited wetland area, and there are surrounding interferences from human production and living operations. Those places are not the best stopover habitats for Grus leucogeranus; at Etoupao in Momoge where those birds gather in large numbers, the surface water comes from returned water from paddy fields, which contains a large quantity of pesticides and chemical fertilizers. If the birds stay there long and get foods nearby, pollutants will be enriched in the bodies of Grus leucogeranus, thus jeopardizing the health of this species.The 4 autumn stopover sites in Hunan, Hubei and Anhui in Yangtze River middle and lower reaches are not reused in spring, and it is probable that Grus leucogeranus will not stop over there in spring Migration.3) Stopover site stability evaluationGrus leucogeranus stopover site utilization frequency in 05-09 springsProvince Wetland 2005 2006 2007 2008 2009 frequency1 Anhui Baidang Lake Wujindu √2 Anhui Caizi Lake (Dongfengwei) √3 Shandong Dawenliu wetland restoration zone √ √ √ 60%4 Shandong 121 coastal shoals √ 20%5 Shandong Yellow River estuary wetland √ 20%6 Hebei Changzhou City suburb √ 20%7 Hebei Huanghua City Huanandian Wetland √ 20%8 Hebei Tangshan Leting Wangtan Town Xinhai √ 20%9 Hebei Changli Tuanlin Xinlizhuang Wetland √ 20%10 Liaoning Shuangtaihekou √ √ √ 60%11 Liaoning Huanzidong √ √ √ √ 80%12 Liaoning Santaizi Reservoir √ 20%13 Liaoning Huagu Reservoir √ 20%14 Liaoning Wolong Lake √ √ √ √ √ 100%15 Jilin Shuangliao Sanhetun √ √ √ 60%16 Jilin Baolawendu √ √ √ 60%17 Jilin Xianghai √ 20%18 Jilin Tongyu Shihuadao √ 20%19 Jilin Boluo Lake √ √ √ 60%20 Jilin Momoge √ √ √ √ 80%21 Jilin Zhenlai Red Flag Horse Farm √ 20%22 Jilin Zhenlai Baiyintaohai √ √ √ √ 80%23 Jilin Zhenlai Chuangye √ √ 40%24 Heilongjiang Tailai Wetland √ √ √ 60%25 Heilongjiang Zhalong Nature Reserve √ √ √ √ 80%26 Heilongjiang Xingkai Lake Nature Reserve √ 20%27 Inner Mongolia Tumuji Nature Reserve √ √ √ √ √ 100%28 Inner Mongolia Dalai Lake Nature Reserve √ 20%The wetlands used by Grus leucogeranus as stopover sites in each of 5 springs are Inner Mongolia Tumuji and Liaoning Wolong Lake, with utilization frequency of 100%. Those places are the most reliable stopover sites for Grus leucogeranus in autumn; followed by 4 sites with 80% utilization frequency, namely Liaoning Huanzidong, Jilin Momoge, Zhenlai Baiyintouhai, and Heilongjiang Zhalong; stopover sites with 60% utilization frequency include Shandong Yellow River Delta, Jilin Baolawendu, Boluo Lake, Shuangliao Sanhetun, Liaoning Shuangtaizi Hekou, and Heilongjiang Tailai; other stopover sites are only used by Grus leucogeranus in 1 or 2 years over the 5-year period, with a poor utilization rate of 20-40%. They are just randomly used as stopover sites, or they may be discarded by the species due to fragile habitat conditions and outside interference. The number of those stopover sites is 13, accounting for 46.4% of spring stopover sites, and they are mainly located in North China region.2) QuantityQuantity and trendsIn 2005-2009 springs, the number of Grus leucogeranus recorded annually is 972-4890, including 72-723 in Inner Mongolia, Heilongjiang monitoring region; 243-4701 in Liaoning, Jilin monitoring region; 3-43 in North China monitoring region; 3-11 in middle and lower Yangtze River monitoring region. Obviously, Liaoning-Jilin region is home to the highest number of those birds. The highest number of the species recorded in 2009 autumn makes up 96.1% of the maximum quantity in eastern China. North China and especially Yangtze River middle and lower reaches record a small number of this species. The number recorded in 2009 spring accounts for only 0.5% of total quantity.Population size of Grus leucogeranus in 2005-2009 springsYear Total Heilongjiang-Inner Mongolia Liaoning-Jilin North China Middle and lower Yangtze RiverRegion Inner Mongolia Heilongjiang Region Jilin Liaoning Region Hebei Shandong Region Anhui2005 972 723 436 287 243 136 107 3 3 3 32006 1838 433 44 389 1391 960 431 3 3 11 112007 1749 72 26 46 1634 1330 304 43 36 72008 3752 600 404 196 3144 2096 1048 8 82009 4890 163 123 40 4701 2644 2057 26 5 21Total 13201 1991 1033 958 11113 7166 3947 83 41 42 14 14Over 5 springs, the quantity of Grus leucogeranus recorded are on the rise.

The high ratio occurs in North China and Yangtze River middle and lower reaches. Since the quantity of stopover population does not exceed 11 and most of them are family groups, the ratio of young birds to adult ones is undoubtedly high. This ratio is not representative for spring migration species. The number of stopover Grus leucogeranus in Momoge in 2009 spring is 2616, of which 195 young cranes are recorded. Young cranes account for 7.5% of population size. Though this figure is below the statistical value on Songliao Plain, it shall be closest to actual situation.In terms of ratio of young cranes to the group, the ratio in spring is 2.5% less than the ratio in autumn on Songliao Plain; in Momoge, the ratio in spring is 3.7% below the ratio in autumn. All this reflects the population loss after Grus leucogeranus return from their southward migration.4) MigrationBased on years’ study of Grus leucogeranus in Jiangxi Poyang Lake, from the first ten days of each March wintering Grus leucogeranus begin to “gather” and fly north about one week later or from the middle ten days of March. In Yellow River Delta, Grus leucogeranus are first observed in the middle ten days of March, and stay there for about 7 days before flying away; Liaoning Shuangtaihekou first records Grus leucogeranus in the last ten days of March; Jilin Baolawendu Reserve first witnesses Grus leucogeranus in the mid-to-last ten days of March, while Momoge Reserve generally records Grus leucogeranus flying back in the last ten days of March. After arriving at Northeast China Songnen Plain, Grus leucogeranus usually stop over for 30-40 days, and some of Grus leucogeranus populations continue to fly north at the end of April. By the first ten days of May, all Grus leucogeranus fly away.For 3 springs (2007-2009), most of Grus leucogeranus fly back to Momoge Reserve in the mid-to-last ten days of every March and leave in the first-to-mid ten days of May. The stopover there lasts 65 days. In 2007-2009 springs, the stopover quantity of Grus leucogeranus at Momoge differs:The dynamic change in stopover quantity of Grus leucogeranus in 2008 spring meets the previously observed rule, namely three stage of rising quantity, relative stability and falling quantity.In 2007 spring, the quantity of migrating Grus leucogeranus at Momoge rises gradually. Grus leucogeranus first appear on March 24 and it takes 41 days for the figure to reach the annual peak of 1273 birds until May 3; later no relative stability period at high quantity level comes up. Instead the quantity falls sharply after May 5 and all cranes fly north within less than 5 days.In 2009 spring, Grus leucogeranus are first observed on March 14, followed by a lengthy migration period. The stopover quantity reaches similar peaks on April 13 and April 30 separately. The value of each peak is about 2600. Following a 15-day period after April 30, the quantity of Grus leucogeranus continues to fall and all cranes leave by May 15. This complies with the Grus leucogeranus stopover rule in this site to some extent.Migration trend of Grus leucogeranus in Momoge in 2007-2009 springsQty.

protection measuresSection 1 Threats to stopover sites for Grus leucogeranus and other waterbirds of international importanceOn Siberian cranes’ flyway, cranes, storks and other waterbirds of international importance and their habitats are threatened in the following aspects:1. Persistent droughts worsen water shortage facing wetlands in North China and Northeast China, which reduces wetland area, degrades ecological quality and destroys many migration stopover sites for cranes and storks. Traditional Grus leucogeranus spring stopover sites like Liaoning Faku Sanmianchuan, Erbaifang core zone of Jilin Xianghai Reserve, and Jilin Zhenlai Sanmenwangjia now record no Grus leucogeranus;2. Declining water level of lakes and marsh wetlands aggravates land reclamation by farmers living around wetlands. This operation goes from bad to worse despite prohibitions. Even within nature reserves, this act cannot be effectively contained. During 2005 spring survey in Momoge Reserve, tractors were found plowing and cultivating in Harnao Dam along Nenjiang River. The majority of reed marshes along Taoer River are contracted and exploited. This phenomenon is prevalent in Northeast China and North China;3. The density and intensity of aquaculture in Yangtze River middle and lower reaches and Bohai Rim increase with each passing day. Excavation at lake beaches and coastal shoals for fish ponds destroys original vegetation; excessive human activities make it hard for waterbirds to find a peaceful habitat; the introduction of new aquatic product species jeopardizes ecological safety of local aquatic species;4. Unreasonable wetland utilization modes are still underway. Out of concern for official performance or economic growth, some local governments or departments propose and implement projects like “10000-mu afforestation”, “land reclamation from sea” and “creation of cash forests”, thus changing the previous purposes of many wetlands. This problem is prevalent in Yangtze River middle and lower reaches.5. Water pollution, poaching, poisoning, oil development, port construction, tourism development and similar problems are also threatening the survival of waterbirds. Those adverse factors cannot be thoroughly solved in a short time.5.2 Adopted protection & management measures and result evaluationDuring surveys in 2004-2009, relevant provinces (autonomous regions), city governments and competent departments on Siberian cranes’ flyway have taken the following protection & administrative measures:1) Wetland water replenishment activities for 4 Siberian Crane GEF project points, namely Zhalong, Momoge, Xianghai and Keerqin, have been conducted according to project arrangement. The work of Nenjiang River water diversion into Momoge Reserve, implemented along with the project, has been started with initial effect already achieved;2) The work of diverting Songhua River water into Jilin Nong’an Boluo Lake Wetland has been conducted for 2 years. In 2005, the proposal was submitted to Changchun People’s Congress for deliberation and then the fund for water diversion was put in place. Relevant units were coordinated and the long-term effective water diversion mechanism was realized. Through wetland water engineering, Boluo Lake’s ecological environment has turned for the better, and now it becomes an important habitat for waterbirds including Grus leucogeranus;3) A wetland waterbird preservation zone is being proposed where Jilin Songhua River, Second Songhua River and Nenjiang River converge. So far relevant applications have been completed; relevant departments are preparing to build nature reserves at coastal area of Liaoning Jinzhou and Liugu Hekou in Huludao;4) Under suggestion of monitoring survey teams, relevant units are applying for the construction of 3 preservation zones in the west of Jilin aimed at protecting wetlands and waterbirds;5) With existing two national nature reserves namely Yellow River Delta and Hengshui Lake, North China monitoring region has developed Cangzhou Nandagang Wetland, Tianjin Beidagang Wetland and Tuanpowa Reservoir into provincial /municipal reserves;6) For Hebei Cangzhou Haixing Wetland, the provincial reserve application work has been initiated, and the project has passed expert demonstration and now awaited approval from provincial government;7) Hebei wetland management authorities at various levels have taken advantage of incoming river water last winter and this spring to proactively accumulate water for wetlands, thus improving wetland ecological environment and reversing the degrading trend. As a result, aquatic plants grow rapidly and attract more waterbirds in species and quantity this spring.5.3 Suggestions on protection and administration1) Government and People’s Congress at various levels shall draft laws and regulations on wetland protection as soon as possible and provide legal guarantee for wetland protection and administration;2) The nation shall strengthen the construction of wetland reserves in funds, policies and other aspects to help boost the capability and level of reserve wetland and waterbird protection & administration;3) The State Forestry Administration shall give attention and support to significant wetlands on Siberian cranes’ flyway in distributing nationwide wetland preservation engineering expenses;4) Continue to build a batch of wetland reserves at the earliest time possible. At places where has no enough conditions for reserve construction but are important habitats for Grus leucogeranus, preservation zones in different systems shall be set up, such as Haixing Yangcheng Reservoir, Huanghua Guangyangchang Reservoir, Huanandian, Qinhuangdao Qilihai, Air Forces Range, Tangshan Leting Wangtan Xinhai and other zones proposed by North China monitoring region;5) Develop popular science education on wetlands and waterbirds to enhance public awareness of wetland & waterbird protection.Unitrans世联翻译公司在您身边,离您近的翻译公司,心贴心的专业服务,专业的全球语言翻译与信息解决方案供应商,专业翻译机构品牌。无论在本地,国内还是海外,我们的专业、星级体贴服务,为您的事业加速!世联翻译公司在北京、上海、深圳等国际交往城市设有翻译基地,业务覆盖全国城市。每天有近百万字节的信息和贸易通过世联走向全球!积累了大量政商用户数据,翻译人才库数据,多语种语料库大数据。世联品牌和服务品质已得到政务防务和国际组织、跨国公司和大中型企业等近万用户的认可。 专业翻译公司,北京翻译公司,上海翻译公司,英文翻译,日文翻译,韩语翻译,翻译公司排行榜,翻译公司收费价格表,翻译公司收费标准,翻译公司北京,翻译公司上海。
