Invasive grass poses serious threat to Alabama ecosystems
In a recent government meeting, officials discussed the growing concern over invasive plant species in Marion County, Alabama, particularly focusing on Kogan grass. This species, which has been spreading from Mobile Bay, poses significant challenges for local ecosystems and land management.

Participants highlighted that Kogan grass is a prolific seed producer, with its peak growth period occurring in early spring, specifically around February and March. The grass is known for its resilience, as it can remain dormant in the soil for extended periods. A troubling report from Lawrence County indicated that Kogan grass re-emerged seven years after being treated, underscoring its invasive nature.

The discussion also compared Kogan grass to other invasive species, such as Johnson grass. While Johnson grass can potentially be managed through grazing or mowing, Kogan grass requires herbicide for effective control. The participants noted that Kogan grass contains oils that can lead to extremely hot fires, posing a risk to surrounding vegetation, including trees.

Officials emphasized the importance of collaboration with landowners to manage these invasive species effectively. The meeting concluded with a commitment to continue efforts in educating the community about the threats posed by Kogan grass and other invasive plants, aiming to protect the local environment and improve land management practices.
