Prescribed burns help Oak Savanna at Sherburne Refuge

Submitted Article
Sherburne National Wildlife Refuge is planning a series of prescribed burns to be conducted during the spring season to help maintain the natural habitats for wildlife and reduce the chance of wildfires outside the refuge.  The refuge averages around 4,000 acres of prescribed burning each year.  Last year Sherburne Refuge only conducted 16 prescribed burns for 748 acres due to the cold and wet spring season.  
Prescribed burns, fires that are carefully planned, are beneficial to native prairie and oak savanna plant communities at the refuge. The burns are conducted under a special set of guidelines for weather and safety called a "prescription."   These prescriptions are planned to accomplish specific objectives for vegetation and wildlife management.  Before a burn begins, temperature, relative humidity, fuel conditions, and wind speed and direction are measured.  Refuge staff takes into account smoke drift, nearby buildings, livestock, and other safety factors when deciding whether to burn.  According to Seth Grimm, Fire Management Officer, the burn is conducted only if conditions meet the approved "prescription."  “We want the public to know that safety is our utmost concern.  By reducing fuels through prescribed burning, we not only benefit wildlife, but also minimize the threat that wildfires on or around the refuge may have to the surrounding public,” says Grimm. 
Through habitat management programs, such as prescribed burning, Sherburne National Wild-life Refuge is restoring the natural ecosystem.  The oak savanna ecosystem, with its plants and wildlife, is adapted to fire and depends on periodic burning for continued existence.
Prescribed burns at Sherburne Refuge are planned to be conducted in April and May, or in the fall, when weather and safety conditions are right to meet the objectives of the burns.  Sherburne National Wildlife Refuge is located north of Zimmerman on County Road 9.
