Description

This document describes the data used to create intact habitat cores (intact or minimally disturbed areas at least 100 acres in size and greater than 200 meters wide) for the U.S. This document also documents the methods used to model Intact Habitat Cores, or minimally disturbed natural areas at least 100 acres in size and greater than 200 meters wide. Esri created these data following a methodology outlined by the Green Infrastructure Center Inc. These data were generated using 2019 National Land Cover Data. Cores were derived from all “natural” land cover classes and excluded all “developed” and “agricultural” classes including crop, hay and pasture lands. The resulting cores were tested for size and width requirements (at least 100 acres in size and greater than 200 meters wide) and then converted into unique polygons. This process resulted in the generation of over 500,000 cores.

See this tile layer for a version that enables rapid visualization with popups and querying. For the individual feature service, see this layer

The previous 2017 version can be found here for map packages and here for a map service.

          Your tile layer is ready to use
          This tile layer will automatically create tiles as needed and cache them for future use. No further configuration is required. View the Settings tab to change the default options. Build tiles manually for specific scales and extents to improve display performance for the first person to view the tile layer at that scale and extent. Tiles must exist if the layer will be used offline.
