U.S. Fish & Wildlife ServiceThe Central Grasslands Roadmap was determined by a sub-committee of the CGR metrics group including experts on birds, other wildlife, and landscapes. It is based on three datasets: the Commission for Environmental Cooperation (CEC) Great Plains ecoregion boundary, grassland Migratory Bird Joint Ventures, and grassland Partners in Flight Bird Conservation Regions. In general, the CGR boundary covers the maximum extent of the three datasets. The goal with the boundary was to represent all sub-habitats within the Great Plains and areas critical for migratory and resident avian species.ArcGIS FeatureLayerhttps://hub.arcgis.com/datasets/0212e74fc63e4aa989a71b0f6c2dcb1b_0engU.S. Fish and Wildlife Service Open DataPublicNorth American Central Grasslands [United States]Web servicesUnited StatesLast Modified: 2022-04-19
