Threatened migratory shorebird habitat mapping DECCW May 2006

## **Abstract** \n\nThis dataset and its metadata statement were supplied to the Bioregional Assessment Programme by a third party and are presented here as originally supplied.\n\n\n\nOriginally digitised very poorly, this dataset has been fixed as much as posssible. Important feeding habitats and roosting sites for seven species of migratory shorebirds (waders) were plotted on GIS software using air photos as templates. Data for this process was obtained from a variety of sources to provide numbers of birds recorded at each of the sites. The habitat mapping was done from first hand experience in the field by the author and/or from local ornithologists with particular skills in shorebird identification and local knowledge of habitats used by shorebirds. The accuracy of the data plotted will not always match the topography, such as shoals, sand spits or shorelines because these are constantly changing (the air photos used are at least 10 years old).However this is the most precise shorebird mapping available.\n\n\n\nThis dataset has been provided to the BA Programme for use within the programme only. Third parties should contact the NSW Office of Environment & Heritage (http://www.environment.nsw.gov.au/).\n\n## **Dataset History** \n\nLineage: GIS data created by a consultant who innacurately indicated that he knew how to use GIS. All existing data on shorebird distribution (foraging and roosting records) held by bird groups, specialists and DEC Wildlife Atlas were reviewed and updated where information was available and checked for inaccuracies. , Data was also updated where required as a result of changes to estuarine habitats through the use of aerial photography. Where necessary face to face meetings were arranged with relevant people to obtain input from other shorebirdspecialists, failing this communication was by phone or email. Digitised air photos provided by DEC were used to map all known shorebird foraging habitat and roost sites along the NSW coast, noting habitat utilised by threatened migratory shorebirds, specifically Sanderling, Great Knot, Greater Sand Plover, Lesser Sand Plover, Broad-billed Sandpiper, Black-tailed Godwit and Terek Sandpiper.\n\n## **Dataset Citation** \n\nNSW Department of Environment, Climate Change and Water (2010) Threatened migratory shorebird habitat mapping DECCW May 2006.

## 摘要
本数据集及其元数据声明由第三方提供给生物区域评估计划（Bioregional Assessment Programme），此处按原始提交版本呈现。

本数据集最初数字化质量极差，现已完成最大程度的修复。本研究以航空照片为底图，在地理信息系统（GIS）软件上绘制了7种迁徙滨鸟（鸻鹬类）的重要觅食栖息地与停歇位点。本过程所需数据来自多类来源，用于统计各站点的鸟类记录数量。栖息地制图工作由作者基于实地一手经验完成，或由具备滨鸟识别专业技能与滨鸟栖息本地知识的当地鸟类学家完成。由于滩涂、沙嘴或海岸线等地形始终处于动态变化中（所用航空照片距今至少已有10年），绘制的数据精度未必能完全匹配实地地形。但本数据集仍是目前可获取的精度最高的滨鸟栖息地制图成果。

本数据集仅提供给生物区域评估计划内部使用。第三方如需获取相关内容，请联系新南威尔士州环境与遗产办公室（NSW Office of Environment & Heritage，http://www.environment.nsw.gov.au/）。

## 数据集历史
### 溯源
本地理信息系统（GIS）数据由一名错误宣称自己掌握GIS使用技能的顾问创建。研究团队梳理了鸟类团体、专家及新南威尔士州野生动物图集（DEC Wildlife Atlas）所收录的所有现有滨鸟分布数据（觅食与停歇记录），在信息可获取的范围内进行更新，并核查其中的不准确之处。此外，结合航空摄影所识别的河口栖息地变化情况，对数据进行了必要更新。如需补充信息，研究团队与相关人员安排面对面会议以获取其他滨鸟专家的意见；若无法开展线下沟通，则通过电话或电子邮件进行交流。本研究利用新南威尔士州环境与遗产部（DEC）提供的数字化航空照片，对新南威尔士州（NSW）沿岸所有已知的滨鸟觅食栖息地与停歇位点进行制图，并重点标注了受威胁迁徙滨鸟所利用的栖息地，具体包括三趾鹬（Sanderling）、大滨鹬（Great Knot）、大沙鸻（Greater Sand Plover）、小沙鸻（Lesser Sand Plover）、阔嘴鹬（Broad-billed Sandpiper）、黑尾塍鹬（Black-tailed Godwit）以及翘嘴鹬（Terek Sandpiper）。
