Focus Areas which encompass concentrations have been identified using both a weighted raster analysis and a hot spot GIS analysis of state and federal ranked element occurrences. These Ecological Focus Areas have been delineated using the following data.
These polygons, created by PA Natural Heritage Program biologists with input from DCNR, PA Game Commission and PA Fish and Boat Commission provided boundaries for many known populations of Rare, Threatened or Endangered species as well as delineated potential habitat areas and supporting landscapes.
Rare, Threatened, Endangered, Candidate, and Tentatively Undetermined plant and animal species were used to assess areas for their concentration of biodiversity values. For more information: http://www.naturalheritage.state.pa.us/
Pennsylvania Audubon Important Bird Areas
The PA Ornithological Technical Committee has identified over 80 IBA sites encompassing over two million acres of Pennsylvania's public and private land. These areas include migratory staging areas, winter roost sites and prime breeding areas for songbirds, wading birds, and other species. These Areas were used to further expand boundaries for Focus Areas and to ensure that some of the most ecologically critical bird habitat in the PA State Forest system was included in further analysis. For more information and maps of these IBAs, please visit: http://iba.audubon.org/iba/viewState.do?state=US-PA
The Important Mammal Areas were created by the PA Mammal Technical Committee to promote the conservation of mammals by identifying sites or regions that include habitats critical to their survival, and to educate the public about mammals and their needs.
Allegheny WoodratHabitat Data
The PA Game Commission has also provided additional data to DCNR which indicate appropriate geology and habitat for Allegheny woodrats across PA as well as data representing known metapopulations for this species. This information has been collected and analyzed by Game Commission biologists and was used in this anlalysis to better delineate Focus Areas which included known Allegheny Woodrat populations on State Forest lands.
“…places in Pennsylvania that represent clusters of Species of Greatest Conservation need, most critically imperiled plant species, and associated habitats where collaborative conservation action should be targeted.”
Resiliency and Connectivity Analysis (TNC; considered): Identifies large forest patches with exceptional resilience and connectivity in a regional context. BOF lands ranked highly in this analysis.
Active River Area Model & Northeast Aquatic Habitat Classification System (TNC; considered): Identifies forested headwaters as well as high value riparian corridors and floodplains.
