Pennsylvania Spatial Data Access

Abstract:

The aim of landscape ecosystem classification and mapping is to distinguish appropritely sized ecosystems - useful and functional land units that differ significantly from one another in abiotic characteristics as well as their related biotic components.  This subdivision of a large area into distinctive landscape ecosystems provides a much needed framework for integrated resource management planning; for biological conservation; and for comparison of differences in composition, occurrence, interactions, and productivity of plants and animals among ecosystems on the Allegheny National Forest (ANF).

Purpose:

The purpose of this data is to support project-level planning, decision making, implementation and monitoring for Forest Service managers, GIS Specialists and others.
