Frequently Asked Questions

  • This preserve is open year round. 

    The month of May is one of the best times of the year to visit this preserve as migratory songbirds are either resting, en route to other destinations, or settling on breeding territories for the summer.

    In mid-September, take a walk down the trail leading to Little Trout Lake and enjoy the spectacular beauty of an autumn day. 

  • The Carl A. Gerstacker Preserve is a wonderful place to hike, snowshoe, cross country ski, watch for birds and other wildlife, take photos and enjoy the sights and sounds of nature. Swimming, [NR1] kayaks and canoes are permitted on Lake Huron. (Vessels must be carried from the parking area.) The preserve also allows geocaching and hunting.

    The Nature Conservancy allows bow hunting for white-tail deer on this preserve to reduce threats too many deer pose to our conservation targets and to ensure that the preserve does not become a “refuge” for deer during the hunting season. In order to be eligible to hunt at this preserve, hunters are required to receive a permit from TNC, follow TNC hunting program rules and comply with all local, state and federal laws and ordinances governing hunting activities, including obtaining all required government licenses or permits.

    The excel sheet from conservation said that swimming is allowed at the preserve. I feel like legal should weigh in on that …. We likely need some language about this being at your own risk/there is no lifeguard on duty, etc.

    OPDMDs

    ​​OPDMD’s are prohibited anywhere on the Carl A. Gerstacker Preserve, as trails are unsafe for OPDMD’s to drive and contain sensitive natural features. The two-track roads could accommodate OPDMD’s, but The Nature Conservancy is not in a position to determine who may or may not access the private lands needed to reach our preserve, and we are not able to monitor their safe and responsible use.​

    We encourage you to hike open trails and enjoy bird and wildlife watching and other permitted activities. Please do not trespass (or park) on private property adjacent to Conservancy preserves. Property lines are clearly marked with yellow signs featuring the Conservancy’s logo. To protect the plants and wildlife that call the preserve home, TNC prohibits the following:

    ·      Biking and mountain biking

    ·      Camping, campfires and cooking

    ·      Caving

    ·      Fishing (except by permit on designated preserves)

    ·      Horseback riding

    ·      Hang gliding or paragliding

    ·      Drones – aka Personal aircraft, Unmanned Aircraft Systems (UAS) and Unmanned Aerial Vehicles (UAV) — Self-propelled or other aircraft are prohibited from taking off, landing or being operated on any TNC preserve except for official TNC purposes, approved research, or in an emergency landing situation. We prohibit the private use of drones on our preserves for the following reasons:

    o   Privacy and enjoyment of other preserve visitors – In order to avoid capturing images of people who are not related to TNC, and from whom a necessary photo release has not been obtained.

    o   Wildlife disturbance – To make sure drones will not disturb resident wildlife, especially areas with many birds or ground based nests.

    o   Preserve management – Unauthorized drones operating in areas where active land management is taking place, such as prescribed burning, could lead to potentially dangerous interactions.

    o   Respecting neighboring property – Preserve boundaries are not always apparent from the ground. We wish to be good neighbors and minimize the risk of drones accidentally crossing over from our preserves to non-TNC property

Preserve Dedication The preserve was officially renamed in 1996 after Carl E. Gerstacker, a founding member of the TNC’s Michigan board of trustees.

Our Work

The preserve was created in 1993 through the generosity of Marilyn Twining and her family who, over a period of years, sold the major parcels of land to TNC in order to protect them as the Little Trout Lake Preserve and the Dudley Bay Preserve.

In honor of a combined grant from The Dow Chemical Company Foundation, the Herbert H. & Grace A. Dow Foundation and the Rollin M. Gerstacker Foundation, the preserve was renamed in 1996 after Carl E. Gerstacker. Gerstacker was the former chairman of the board and director of The Dow Chemical Company as well as a founding member of the TNC’s Michigan board of trustees.
