Invasive Cogongrass (Imperata cylindrica) | Conservation Education


Date: Mar 7, 2021

Cogongrass (Imperata cylindrica) is labeled as one of the 10 WORST weeds in the world, and it's ravaging the Southeastern states such as Alabama and Florida. This invasive grass can entirely smother ecosystems like the beloved longleaf pine, can cost landowners massive amounts of money, and can even threaten human lives! Cogon grass is no joke! In this video we go on a journey to see how bad it can get, and what we can do to stop it.

How To Identify Cogongrass

Cogongrass (Imperata cylindrica) is an aggressive invader of natural and disturbed areas throughout the Southeast. It disrupts ecosystem functions, reduces wildlife habitat, decreases tree seedling growth and establishment success, and alters fire regimes and intensity. Recognizing the presence of cogongrass is necessary before beginning any management activities. While other species may look similar, cogongrass has a unique combination of characteristics that make field identification possible. If you think you have cogongrass on your land, please contact your local Alabama Forestry Commission office. For more information on cogongrass ecology and control, visit

Cogongrass, one of the worst invasive plants in the world, was first found in South Carolina in 1989. In 2004, several locations were found; Since then, the plant has been found in nine counties. These areas are being treated to control the grass and eliminate its spread to other areas. We need people on the ground helping to locate any spots of cogongrass that might exist. We cannot afford to let this plant become established in our state. We have a chance to control the grass if we find the spots while they are small. This year, there will be a coordinated effort to survey for cogongrass- Efforts will be statewide. We need hundreds of volunteers to help with this effort. The Survey is going to be held from May 07-09, 2009. You can learn more about cogongrass thru these video presentaions and also by logging onto
