TOPEKA – Kansas Department of Health and Environment (KDHE) reminds Kansans that March and April are when large areas of the state’s rangelands are burned by prescribed fire, especially within the Flint Hills.
Prescribed fire is a tool used by landowners and managers to help preserve the tallgrass prairie ecosystem, control invasive species, reduce woody encroachment from species such as Eastern Red Cedar and provide better forage for cattle. Prescribed burning also reduces the risk of wildfires and is effective in managing rangeland resources. Smoke from the burns can influence the air quality of downwind areas. The use of smoke management techniques is vital to reduce the air quality and health impacts.
KDHE will activate the Kansas smoke modeling tool in early March, prior to widespread burning in the Flint Hills. The computer models use fire data and current weather conditions to predict the potential contribution of smoke and air quality impacts to downwind areas. There are approximately 2.2 million acres burned on average in the Flint Hills of Kansas and Oklahoma each year.
“We are entering the 14th year that we have been able to provide this important tool for the prescribed fire community,” Jayson Prentice, meteorologist at the KDHE Bureau of Air, said. “We continue to encourage ranchers and land managers to utilize smoke modeling resources, such as the smoke modeling tool to mitigate potential air quality impacts.”
Prescribed burns release large amounts of particulate matter and other pollutants that can form ground-level ozone. Particulate matter and ozone can cause health problems, even in healthy individuals. Common health problems include: burning eyes, runny nose, coughing and illnesses such as bronchitis. People with respiratory conditions, cardiovascular diseases, children and the elderly are more vulnerable to experience symptoms.
Steps to protect your health on days when smoke is present in your community include:
- Healthy people limiting or avoiding strenuous outdoor
- Vulnerable people should remain
- Keep indoor air clean by closing doors and windows and running air conditioners with air
- Stay hydrated by drinking plenty of
- Contact your doctor if you have symptoms such as chest pain, chest tightness, shortness of breath or severe
