Wetland Complex DSM for Waterfowl thematic

FOR non-AGOL ACCOUNT HOLDERS, DOWNLOAD THIS GEOSPATIAL DATA HERE: https://gis-fws.opendata.arcgis.com/search?tags=lmvjv We defined a wetland complex as an area of appropriate size for conservation planning with suitable water coverage and persistence, heterogeneity and structure of vegetation, energy density and quality, and sanctuary to provide all of the resources needed by ducks during a portion of the non-breeding period (late fall to early spring). Based on this definition, we developed three primary sub-models for those factors that we could measure geospatially. We developed sub-models for Wetland Type to capture water coverage and heterogeneity of vegetation, Sanctuary, and Energy. The three sub-models were combined into a final Wetland Complex model. Our final Wetland Complex Model highlights several areas on the landscape where multiple habitat components (e.g., optimal configuration of wetland types) are present and create important focus areas for waterfowl conservation planning. The highlighted red areas are where we would predict to see high waterfowl use throughout the winter. The highlighted red areas could also be used as anchor points to improve the surrounding landscape to increase attractiveness to waterfowl. The vector version of this data loses some of the detail and nuance that the original data retains. Please be aware when using the vector data that it is not as precise as the raster format of this data.非AGOL（ArcGIS Online）账户持有者可从此处下载此地理空间数据：https://gis-fws.opendata.arcgis.com/search?tags=lmvjv 我们将湿地复合体（wetland complex）定义为适宜开展保护规划的区域，该区域需具备合适的水域覆盖度与持水持久性、植被的异质性与结构特征、能量密度与质量，以及可为鸭类在非繁殖期（晚秋至早春）的部分阶段提供所需全部生存资源的庇护场所。基于该定义，针对可通过地理空间技术量化的各类影响因子，我们构建了3个核心子模型，分别为表征水域覆盖度与植被异质性的湿地类型子模型、庇护场所子模型与能量子模型。 将上述三个子模型整合后，得到最终的湿地复合体模型。该最终模型识别出景观中同时具备多种栖息地组分（例如最优湿地类型配置）的区域，这些区域可作为水鸟保护规划的关键重点关注区域。标记为红色的区域为模型预测的整个冬季水鸟高频活动区域；同时，此类红色标记区域亦可作为锚点，用于优化周边景观以提升其对水鸟的吸引力。 该数据的矢量格式版本会丢失原始栅格数据所保留的部分细节与细微差异，因此在使用矢量数据时请注意：其精度不及该数据的栅格格式版本。
