• Phase II - Inadequate Habitat for Fish and Wildlife

The following are the potential at-risk maps produced during the Arkansas Resource Assessment - Phase II. The NRCS definition of the natural resource concern and the input layers and land use designation weights that were used for modeling the natural resource concern within the Inadequate Habitat for Fish and Wildlife Resource Concern are listed to the right of each map. More detailed maps are available by clicking the link below each map.
Habitat Degradation (View Individual Data Layers)

    NRCS Definition:
    Quantity, quality, or connectivity of food, cover, space, shelter,        and/or water is  inadequate to meet requirements of identified
