- Title:
-
Hopewell Furnace National Historic Site Vegetation Mapping Project - Spatial Vegetation Data
- Abstract:
-
This shapefile is an alliance-level vegetation map of Hopewell Furnace National Historic Site developed by the Pennsylvania Science Office of the The Nature Conservancy for the National Park Service. The map is based on field work performed in the summers of 2002 and 2003 and aerial photography obtained in 2002.
