The Corridors layer is part of the Upper Neuse-New Hope Landscape Habitat Connectivity Network, a GIS model developed initially for the Eno-New Hope Landscape Conservation Project and expanded and updated for the Durham County Open Space Program to include the entirety of Durham County. Polygons in the Corridors layer represent areas modeled as least cost movement corridors between two Habitat Patch polygons for development-sensitive terrestrial wildlife species. The Corridors layer should be interpreted only in conjunction with the Habitat Patches layer, which is also part of the Upper Neuse-New Hope Landscape Habitat Connectivity Network data set. The layer is intended to be used as an aid to conservation planning only. Current habitat conditions should be verified by biological surveys. Visit the Durham County Open Space Program website for more information. Visit the Eno-New Hope Landscape Conservation Group website for background information on the initial phase of this GIS project.
