Forest Management Practices
The Filter Strip
To prevent erosion runoff, a strip of vegetation is maintained between the harvested area or access road and any adjacent water course, such as a stream or lake. The width of the area, or strip, varies according to the steepness of the slope.
"Minnesota's forest industry knows its future depends on an ongoing healthy and growing forest. I have found the industry not only to be cooperative but often independently taking research initiatives and other efforts to help ensure our forests' future."
Gerald A. Rose, Director DNR, Division of Forestry
Forest Management Practices Ensure Forests' Future
Forest management involves more than harvesting trees. It also involves sensitivity to other natural resources. Industry members exercise great care in following the 97 recommended practices to protect water quality, which were developed in cooperation with the U.S. Forest Service, the University of Minnesota, and the Department of Natural Resources. Known as "Water Quality Best Management Practices" (BMPs), these guidelines help ensure that timber harvesting has minimum impact on water quality.
These practices include:
- Establishing "filter strips" and "shade strips" near streams and lakes to control runoff and protect fish.
- Minimizing erosion and sedimentation caused by construction and maintenance of forest access roads.
- Seeding, filling in ruts and installing water bars and erosion barriers.
- Preventing the spilling of fuels and lubricants.
