Partner_impoundments

This layer is part of a web map was developed by the Atlantic Coast Joint Venture (ACJV) to display existing spatial layers with mapped waterfowl impoundments in the ACJV geography (group layer “Impoundments 2015, 2018, DNREC 2025) and to incorporate partner input on locations of impoundments that are not yet mapped within this layer. To help identify impoundments, the map displays layers with eBird checklist data (v Nov 2025) from American Black Ducks (ABDU) and Mallards (MALL) that contained the word ”impoundment" in either the species comments or the locality name within the eBird data. The layer “Impoundments Polygons from Partners” is an editable layer that allows partners to digitize locations of impoundments and add basic information to the attributes field. The overarching goal is to develop a more complete spatial inventory of waterfowl impoundments throughout the ACJV to help inform conservation and restoration priorities.本图层隶属于大西洋海岸联合企业（Atlantic Coast Joint Venture, ACJV）开发的网络地图。该网络地图旨在展示ACJV辖区内已完成测绘的水禽蓄水区（waterfowl impoundments）空间图层，其分组图层为"Impoundments 2015, 2018, DNREC 2025"，同时吸纳合作伙伴提供的、尚未纳入本图层的蓄水区位置信息。为辅助识别蓄水区，该地图还展示了2025年11月版eBird观测记录表数据，筛选条件为记录涉及美国黑鸭（American Black Duck, ABDU）与绿头鸭（Mallard, MALL），且其物种备注或观测地点名称中包含"impoundment"一词。"Impoundments Polygons from Partners"图层为可编辑图层，合作伙伴可通过该图层数字化录入蓄水区位置，并向属性字段添加基础信息。本项目的核心目标是构建覆盖ACJV全境的更完整水禽蓄水区空间清查清单，为水禽保护与修复优先级划定提供决策支撑。
