Bass Lake Prescribed Burn

News Release Date: April 12, 2021

The National Park Service (NPS) plans to conduct a prescribed fire in up to four burn units this spring, as soon as April 22, at Sleeping Bear Dunes National Lakeshore (National Lakeshore). Prescribed fire is a management tool used to maintain healthy ecosystems, replenish fire dependent ecosystems, reduce available fuels in the event of wildfire, and assist with the management of invasive species. The 2021 treatment units cover just under 2,500 acres within the National Lakeshore’s Platte River District in Benzie County, between Esch and Peterson Roads and north of M-22. For safety, the White Pine Backcountry Campground and some of the small roads and trails in the park will be closed to visitors during the active burning period. This is the second broadcast (wide area) prescribed fire to be held at the National Lakeshore, following one successfully held in 2019 in the same area of the park. 

 

The area of Platte Plains to be burned contains unique, fire-dependent plant communities known as dry northern forest and wooded swale. Dry northern forest is typically dominated by a mix of hardwoods and jack pine or red pine. Wooded swales are low areas between post-glacial ridges that support forested wetlands and a variety of wildflowers and other herbaceous plants. Both are important to the diversity of the Sleeping Bear Dunes ecosystem.

 

To ensure safe execution of the prescribed fire, and effective conservation of the dry northern forest and wooded swales, the burn will be conducted only under a specific set of weather and fuel conditions, or “prescription.” The actual burn date(s) will depend upon NPS fire staff monitoring weather forecasts and fuel moisture to determine if and when prescription conditions are met. In addition to safety, smoke dispersal is a primary concern, and wind direction and speed will be monitored prior to ignition to minimize smoke drifting into developed areas and roadways from the remote fire location. Trained and experienced federal fire personnel will conduct the prescribed fire.  

Prior to European settlement approximately 180 years ago, majestic dry northern forests were common in the northern Lower Peninsula of Michigan. Logging and suppression of naturally-occurring wildfires led to the decline of this forest type in the Great Lakes region. Red and jack pine usually rely on fire to regenerate and many of the species found within wooded swales need openings in the canopy for access to sunlight. Without fire as a disturbance, the slow encroachment of hardwood species and shrubs eventually outcompetes the pines, altering community composition and canopy structure. Conserving these remnants of high quality dry northern forests and wooded swales through prescribed burns will allow National Lakeshore visitors to continue to experience an ecosystem that represents a bygone, wild component of Michigan’s natural history. In addition, burning under controlled conditions will reduce fuel loads and reduce the risk of uncontrolled wildfire in the future.

The Great Lakes Restoration Initiative (GLRI) provides funding for these prescribed fires as part of its purpose in protecting and restoring the largest system of fresh surface water in the world – the Great Lakes. The Platte Plains prescribed fire supports GLRI’s goals of protecting imperiled native plant and animal habitats and controlling invasive plant species around the Great Lakes.

 

Updates regarding burning activities will be posted as “alerts” on the park website.
