![]() ![]() ![]() ![]() KDHE reached out to a diverse group of stakeholders to observe these meetings and provide access to information about this issue. The Committee began the process of developing a Flint Hills Smoke Management Plan (SMP) through a series of meetings in 2010. This has led to an increased interest in the air quality, not only in Kansas, but throughout the United States during the time frame in which the majority of prescribed burning activities occur.Ĭoncerns about the impacts of burning in the Flint Hills region on air quality prompted the Kansas Department of Health and Environment (KDHE) to organize the Kansas Flint Hills Smoke Management Advisory Committee. In past years during the burning season, Kansas Ambient Air Monitoring Network monitors have recorded elevated concentrations of both inhalable particles that are generally 10 micrometers and smaller in diameter (PM-10) and ozone as well as other pollutants downwind of the Flint Hills region. With the majority of prescribed burning activities occurring during this time period, a large amount of particulate matter and ozone precursors are released into the air during a relatively short time period. Burning of the tallgrass prairie generally occurs in early to mid-April. For the benefits of fire as a rangeland management tool to be realized, burning must be initiated at the proper time. Range management practices used throughout the region dictate that fire be used as a tool to prevent intrusion of weeds and woody plants into the stand of prairie grass present, as well as a means to improve the productivity of the rangeland for ranching practices. The Flint Hills were at one time a communal bison hunting ground for the Pawnee, Osage, Wichita, and Kansa, who knew that the area was good grazing ground for bison. The Flint Hills region of Kansas is the largest tract of unplowed tallgrass prairie in North America and one of the few large areas of native prairie remaining in the United States. ![]()
