Colonial National Historical Park Natural Resource Condition Assessment

Colonial National Historical Park Natural Resource Condition Assessment

The National Park Service is carrying out assessments of the natural resource condition (NRCA) for nearly 300 of the National Parks throughout the country deemed to have significant natural resources. This project, to assess condition of Colonial National Historical Park in Virginia, is a synthesis project aimed at collating and synthesizing all available data to assess current status and trend for each metric, combining these into an overall framework. The focus of this study has been to develop a habitat based framework to assess natural resource condition.
