In April and May each year, the Park Maintenance Division, Bloomington Fire Department and U.S. Fish and Wildlife Service conduct prescribed burns together to restore the native prairies, wetlands and park landscapes within the City of Bloomington.
Prescribed burns do a lot of good. They:
Remove built-up thatch material and weed seeds.
Invigorate new growth and seeding of desirable native plants, trees and wildflowers.
Help to control invasive tree and shrub species that threaten species native to the ecosystem.
Minimize the spread of pest insects and disease.
Improve habitat for threatened and endangered species.
Reduce hazardous fuels, protecting human communities from extreme fires.
The Park Maintenance Division has developed a three- to five-year burn rotation plan that encompasses park areas in Bloomington that meet the requirements and restrictions established by the Minnesota DNR, state legislation and City ordinance.
To minimize risk to residents and property, prescribed burns are conducted only when:
Fuel in the burn area is dry.
Wind velocities are moderate, 5 - 15 MPH, in a direction that results in the least amount of smoke impact on the residential area.
Humidity is 35% - 80%.
Air temperature is 32° - 65° F.
Because of these variables, the exact timing may not be known until the day before or the day of the burn. Staff will go door to door in an attempt to notify residents directly adjacent to the burn area on the day of the burn.
The following have been identified as primary locations for 2022.
