This report identifies an approach to quantifying desired conditions for two existing forest communities at Valley Forge National Historical Park (NHP); a Dry Oak Forest community and a Successional Tuliptree Forest community. The framework of the National Vegetation Classification System (NVCS) was used to write the descriptions for the desired conditions and compare target communities to globally described associations.

This document details the vegetation classification and mapping which was completed for Saugus Iron Works National Historic Site, It includes a current digital geospatial vegetation database for the park. Six vegetation associations occurred within the park, and these were identified and described in detail. The associations were Northeastern Modified Successional Forest, Reed Canarygrass Eastern Marsh, Reed-grass Tidal Marsh, Cattail Brackish Tidal Marsh, Skunk-cabbage - Orange Jewelweed Seep, and Central Atlantic Freshwater Subtidal River Bed.
