Spatial analysis of large mammals to assess harvest vulnerability in relation to anthropogenic factors

August 2012 - December 2014


Participating Agencies

  • Pennsylvania Game Commission

Successful management of large mammals is dependent upon availability of population to harvest in defined management units or season structures. Availability of the population to harvest is also dependent upon landowner distribution and hunter characteristics within management units that species occupy. The inherent changes in movements and populations size of black bear and elk coupled with landscape change and anthropogenic influences on populations requires a detailed assessment of range use and resource selection of both species in Pennsylvania. Many years of radiocollaring and monitoring has provided the necessary detailed locations needed to understand the change in distribution and use of public/private lands throughout the range of both species.
