Davey Resource Group Enhances Wetland Biodiversity In Michigan Through Invasive Vegetation Treatments

Michigan Department Of Natural Resources

In 2023, DRG was contracted by the Michigan DNR to restore Curtis Creek Fen, a 12-acre biodiverse wetland area. DRG targeted wetland invasives and woody species to enhance biodiversity, using spot treatments and cautious methods to avoid disturbing wildlife.

Maintaining Diverse Habitats

Curtis Creek Fen, a 12-acre area managed by the Michigan Department of Natural Resources (MI DNR), is renowned for its rich biodiversity and high-quality wet meadow ecosystem. Fens, known as biodiversity hotspots, often harbor rare plant and animal species.

Invasive Control Performed With Care

In 2023, Davey Resource Group, Inc. (DRG) was commissioned to restore the native fen habitat by targeting wetland invasive and selective woody species. Project goals aimed at enhancing biodiversity and wildlife habitat by reducing woody and invasive cover by 85–90%. To achieve these objectives, DRG employed spot treatment with low-pressure backpack sprayers and handwicking devices for cattail control while carefully avoiding damage to native vegetation. Woody invasives were removed using brushcutters, and stumps were treated with herbicide. During the project, DRG staff encountered multiple eastern massasauga rattlesnakes, Michigan’s only threatened venomous species. These encounters underscored the need for caution to minimize disturbance to wildlife habitat while implementing treatment methods.
