Invasive Cogongrass Reduced on Southwest Mississippi WMAsWednesday, August 24, 2016
The Mississippi Department of Wildlife, Fisheries, and Parks
(MDWFP) continues to battle cogongrass on wildlife management areas
(WMAs). Cogongrass, an exotic plant species from Asia, has
aggressively expanded its range across Mississippi. Unfortunately,
it is present on most WMAs in South Mississippi.
Cogongrass infestations typically occur in road and utility
right of ways, managed openings, sandbars, and other areas of soil
disturbance. It can spread quickly from an initial patch to acres
in size if left untreated. Cogongrass provides minimal to no value
to wildlife. It quickly outcompetes and displaces native vegetation
that provides food and cover for wildlife.
Each spring, MDWFP personnel locate new cogongrass infestations
on WMAs. Spring is an excellent time to identify cogongrass due to
its white fluffy flowers and seed head. Herbicide applications are
used throughout the growing season to control the invasive species.
Repetitive deep disking can also be effective at controlling
patches in areas accessible by tractor, and where soil erosion is
not a concern. Equipment should be cleaned thoroughly before
transported to other locations to help reduce the spread of
