At the beginning of February, the Harris County Flood Control District conducted a prescribed burn on 440 acres of prairie and wetlands in northwest Harris County near the Katy Prairie. The burn was carefully planned and supervised by certified fire professionals to ensure it stayed safe and contained.
Why This Work Is Important
Prescribed burns help keep prairie and wetland areas healthy. Over time, invasive plants can take over and crowd out native grasses and wildflowers. A controlled burn removes these plants, giving native species room to grow.
Grasses and wildflowers in these areas are adapted to survive fire. Many have deep roots that stay alive underground, allowing them to grow back stronger after a burn.
The Benefits of a Prescribed Burn
- Reducing invasive plants
Certain invasive species are not adapted to fire. A controlled burn can reduce their presence, allowing native plants more room to grow. - Strengthening native grasses
Many prairie grasses have deep root systems. While the top growth may burn, the roots remain protected below the soil. After a burn, these grasses often return thicker and stronger. - Encouraging wildflowers
Wildflowers respond to increased sunlight and improved soil conditions after a burn. With less plant buildup blocking the ground, seeds have a better chance to germinate. Over time, this can lead to more vibrant seasonal blooms. - Improving wildlife habitat
Healthy prairie provides food and shelter for birds, butterflies, bees, and small mammals. When native plants thrive, wildlife benefits. A diverse habitat supports a balanced ecosystem. - Managing built-up vegetation
As plants grow and die back each year, dry material collects on the ground. A prescribed burn removes this buildup in a controlled way, supporting the long-term health and structure of the prairie landscape.
Prescribed burns are one of several tools the Flood Control District uses to maintain ecologically sensitive prairie and wetland areas across Harris County. Just as bayous and channels require regular maintenance, natural landscapes also need careful management to continue functioning as intended.
The Flood Control District is continuing to make historic progress in flood risk reduction projects and maintenance efforts thanks to voter support and dedicated staff. Stay informed by following us on social media.
