ebd_abdu_acjv_impound_agol

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.本图层为大西洋海岸联合工作组（Atlantic Coast Joint Venture, ACJV）开发的网络地图的组成部分，旨在展示ACJV辖区内已完成矢量化的水禽蓄水区空间图层（分组图层"Impoundments 2015, 2018, DNREC 2025"），并纳入合作伙伴提供的、尚未被本图层覆盖的蓄水区位置信息。为辅助识别蓄水区，该地图加载了eBird 2025年11月版的记录清单数据图层，筛选出包含美洲黑鸭（American Black Duck, ABDU）与绿头鸭（Mallard, MALL）的记录，且这些记录的物种备注或地点名称字段中包含"impoundment"（蓄水区）关键词。"Impoundments Polygons from Partners"图层为可编辑图层，支持合作伙伴对蓄水区位置进行数字化采集，并向属性字段补充基础信息。本项目的总体目标是构建ACJV辖区内更完整的水禽蓄水区空间名录，为保护与修复优先级制定提供科学依据。
