Natural Resource Condition Assessment: Saint Croix National Scenic Riverway.

摘要

This Natural Resource Condition Assessment was undertaken to evaluate current conditions for a subset of natural resources and resource indicators in SACN. Using a framework developed by the Science Advisory Board of the United States Environmental Protection Agency (USEPA 2002), natural resources were evaluated in six categories: landscape condition, biotic condition, chemical and physical characteristics, ecological processes, hydrology and geomorphology, and natural disturbance regimes. A total of 52 resources and indicators were evaluated (Table i) by reviewing existing data from peer-reviewed literature and federal and state agencies. Data were analyzed where possible to provide summaries or new statistical or spatial representations.
