Though mountain lions once roamed the hills and forests of Pennsylvania, persecution at the hands of humans drove them locally extinct. If we support open space conservation and preserve corridors connecting potential habitat, we could reverse this situation and bring mountain lions back home to Pennsylvania.
Although mountain lions may be physically capable of living in an area, human activities and attitudes could keep them from reestablishing a population there.
Fragmentation, sport hunting practices, and intolerant communities can wipe out mountain lions from any area.

Before European settlement, mountain lions roamed throughout Pennsylvania and beyond. Perceived conflict with livestock, heavy hunting pressure, conversion of wildlands to agriculture and other forms of habitat loss drove the mountain lions of Pennsylvania to local extinction.
There hasn't been much, if any, research specifically addressing potential habitat for mountain lions in the state, but there has been work looking at the importance of potential dispersal corridors across the U.S. A study by Michelle LaRue (2007) estimates that there are 128,608 square kilometers of highly suitable habitat across the Midwest. Additional habitat certainly exists throughout the South and East Coast as well. A viable population in Pennsylvania would help provide potential dispersing individuals to help repopulate neighboring states where mountain lions once thrived.
Establishing mountain lion-friendly legislation and management practices will likely need to play a role in allowing this top carnivore to return to the great state of Pennsylvania. Check out our Action Tab to see what you can do to help!
