Abstract:
The Appalachian Restoration Campaign (ARC) is dedicated to the restoration and protection of Central Appalachian
wildlands by developing an interconnected system of reserves in which human activity is compatible with ecological
recovery and health. The core of this project is the Central Appalachian Assessment (CAA), focusing on a regional
study area that encompasses portions of six states throughout the Central Appalachians.
Part I of this Assessment
includes an examination of the current landscape within the study area and its suitability for supporting the eastern
cougar (Puma concolor couguar). Suitable cougar habitat still exists within the Central Appalachians, yet prior
studies have not examined the location or availability of habitat. The cougar stands out as an umbrella species for
habitat management due to its extensive home range. If we protect the habitat that falls under this protective
“umbrella”, we could effectively provide for the habitat needs of a number of other species throughout the region.
Using GIS software, this analysis identifies suitable cougar habitat based on the landscape characteristics of prey
density, road density, human population density, and land use. The data for each layer was reclassified and ranked
from 1 to 10 according to its suitability as cougar habitat. The highest suitability rating (10) was given to the
categories of lowest road density, lowest human population density, highest deer density, and forest habitat.
The
reclassified data layers were added using ArcView to create a final composite map, with a total score calculated for
each cell of 5.5 mi2
(14.2 km2
). The composite scores for the CAA study area range from 8 to 40, with 40 being
those cells most suitable as cougar habitat.
The greatest density of high suitability cells within the CAA study area
(total score 37 - 40) is located within the central to northwest section of West Virginia. There are also smaller areas
of dense cells with a high suitability rating (total score 34-40) located in northeastern West Virginia and in northwest
Pennsylvania.
In addition, a large portion of cells which received a high suitability rating (total score 32-40) are
located along the Appalachian mountain chain and within the northern Allegheny plateau. Additional research is
necessary to further identify specific areas of suitable habitat on a smaller scale and to examine these areas in terms
of property ownership and current protection status.
