Inventory & Monitoring Program

Knowing the flora and fauna of Hancock County not only tells us the natural treasures to watch for outdoors, but also helps educate about the changing environment and how best to manage our natural resources from forests to fields or wetlands to wild lands. Various land management procedures and monitoring is conducted throughout the year. These plans are based on scientific knowledge gathered in an on-going Inventory and Monitoring program conducted within the parks and Hancock County by HPD staff and volunteers.

 How can you help? This hands-on in-the-field approach to monitoring environmental changes and assisting with habitat restoration gives participants a wide range of physical and mental activities to participate in. Please dress for the weather, as most of these activities take place outdoors. If registration is required, please call the HPD Main Office at 419-425-PARK/7275. There may be age requirements for some of these activities, Adult Education, requiring min. 18 years old. If you have any questions about the activities please contact Natural Resource Coordinator Sarah Betts at
