Topeka, Kan. – The Kansas Department of Health and Environment (KDHE) has issued a health advisory for air quality in response to prescribed burns set for Friday, March 20.
These burns are happening in the Flint Hills and nearby areas due to favorable weather conditions. KDHE warns that the smoke from these burns, combined with leftover smoke from Thursday, will increase air pollution levels across central and eastern Kansas. The advisory is expected to last until early Saturday afternoon.
Officials expect the Air Quality Index (AQI) to fall between Moderate and Unhealthy for Sensitive Groups. Areas near active burns may even register as Unhealthy. For real-time updates on air quality, check out this resource.
Why Are These Burns Necessary?
Prescribed burning is an annual practice in the Flint Hills. It helps maintain the tallgrass prairie, combats unwanted plants like Eastern Red Cedar and Sumac, and improves pasture for cattle. Moreover, it decreases the risk of wildfires and aids in managing rangeland effectively.
However, it’s crucial to note that these burns can release significant amounts of particulate matter (PM) and ozone-forming substances. Such pollutants can lead to health issues, even for healthy individuals. Symptoms may include burning eyes, coughing, or worsened respiratory problems for those with pre-existing conditions.
Protecting Yourself During Smoke Events
Here are some tips to stay safe when smoke is in the air:
- Limit outdoor activities, especially strenuous ones.
- Stay indoors if you’re particularly vulnerable, like children or those with health issues.
- Keep indoor air clean by closing windows and using air filters in air conditioners.
- Stay hydrated by drinking plenty of water.
- If you experience severe symptoms like chest pain or shortness of breath, consult a doctor.
Ongoing Efforts
KDHE, alongside other partners, is working on the Flint Hills Smoke Management Plan to reduce the impacts of smoke on air quality. This plan includes ways to control and disperse smoke effectively.

In recent years, air quality advisories during burn seasons have become more common, as climate change influences weather patterns. In fact, the American Lung Association reports that wildfires and prescribed burns can affect air quality far beyond the immediate area, leading to health concerns across multiple states.
This renewed focus on air quality highlights a growing awareness of the balance between agricultural practices and public health.
