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 the condition of Gateway National Recreation Area in New York and New Jersey, is aimed at collating and synthesizing all available data to assess current status and trend for each metric, combining these into an overall framework for each park. The focus of this study has been to develop a habitat based framework to assess natural resource condition.
