Summary
Description
This manual has been generated in response to the needs of the National Wildlife Refuge System in USFWS Region to protect habitat of overwintering waterfowl. Its purpose is to aid in developing a basic program to monitor water quality and vegetational changes on refuges. The objective of the monitoring program might be thought of as the establishment of a safety net, catching trends in water quality in time for managers to take action and prevent habitat damage.
