The GLKN Inventory and Monitoring Program, comprised of nine national park units,is one of 32 National Park Service I&M Networks across the country. As a program of the National Park Service, Great Lakes I&M scientists conduct long-term monitoring of critical park resources, or “Vital Signs,” at nine national park units in Michigan, Indiana, Minnesota, and Wisconsin. The Network analyzes and summaries these monitoring data and provides it to the parks so that they can make more scientifically-informed management decisions.

The GLKN consists of nine park units that cover one million acres, extending from the boreal forests of northern Minnesota to the sand dunes of southern Lake Michigan. The parks reflect diverse landscapes and human dimensions ranging from remote wilderness to metropolitan areas.

This web site provides information about the Network's inventory and monitoring work at these parks. Visit the parks in this Network to discover the particular resources found at these special places.

This report recognizes and celebrates the 10-year anniversary of field work monitoring the "vital signs" in our network parks. It also recognizes long-term monitoring being conducted by staff in each of the parks, some of which has been going on since long before the Inventory and Monitoring program came into being. Finally, this report is also our network's contribution to the National Park Service Centennial.
