Modeling Critical Forest Habitat in the Southern Coal Fields of West Virginia

الملخص EN

Throughout the Central Appalachians of the United States resource extraction primarily from coal mining has contributed to the majority of the forest conversion to barren and reclaimed pasture and grass.

The loss of forests in this ecoregion is significantly impacting biodiversity at a regional scale.

Since not all forest stands provide equal levels of ecological functions, it is critical to identify and map existing forested resources by the benefits that accrue from their unique spatial patterns, watershed drainage, and landscape positions.

We utilized spatial analysis and remote sensing techniques to define critical forest characteristics.

The characteristics were defined by applying a forest fragmentation model utilizing morphological image analysis, defining headwater catchments at a 1 : 24,000 scale, and deriving ecological land units (ELUs) from elevation data.

Once critical forest values were calculated, it was possible to identify clusters of critical stands using spatial statistics.

This spatially explicit method for modeling forest habitat could be implemented as a tool for assessing the impact of resource extraction and aid in the conservation of critical forest habitat throughout a landscape.
