The purpose of this map service is to be a base for clipping to state and provincial boundaries in the CED (Conservation Efforts Database https://conservationefforts.org/) custom footprint editor. The custom footprint editor allows CED data providers to edit their spatial data submissions in a web environment.The data is a subset of the World Administrative Division dataset. World Administrative Divisions is a detailed dataset of country first level administrative boundaries which can be used at both large and small scales. It has been designed to be used as a basemap and includes a Disputed Boundaires layer that can be used to edit boundaries to fit a users needs and view of the political world. Included are attributes for name and ISO codes, along with notes identifying disputed boundaries and continent information. Particularly useful are the Land_Type and Land_Rank fields which separate polygons based on their area. These attributes are useful for rendering at different scales by providing the ability to turn off small islands which may clutter small scale views. The sagebrush ecosystem is the largest ecosystem type in the continental U.S., providing habitat for more than 350 associated fish and wildlife species. In recognition of the need to conserve a healthy sagebrush ecosystem to provide for the long-term conservation of its inhabitants, the US Fish and Wildlife Service (Service) and United States Geological Survey (USGS) developed the Conservation Efforts Database version 2.1.0 (CED). The purpose of the CED is to efficiently capture the unprecedented level of conservation plans and actions being implemented throughout the sagebrush ecosystem and designed to capture actions not only for its most famous resident, the greater sage-grouse (Centrocercus urophasianus; hereafter, sage-grouse) but for the other species that rely on sagebrush habitats. Understanding the distribution and type of conservation actions happening across the landscape will allow visualization and quantification of the extent to which threats are being addressed.The spatially explicit, web-based Conservation Efforts Database is capable of (1) allowing multiple-users to enter data from different locations, (2) uploading and storing documents, (3) linking conservation actions to one or more threats (one-to-many relationships), (4) reporting functions that would allow summaries of the conservation actions at multiple scales (e.g., management zones, populations, or priority areas for conservation), and (5) accounting for actions at multiple scales from small easements to statewide planning efforts.
