Cogongrass was first
found in the Francis Marion National Forest in November
2006. This very aggressive Asian grass has the potential to
eliminate plant and animal diversity throughout the Forest.
Cogongrass forms extremely dense stands and it may secrete chemicals
that are toxic to other species. No other plants can
compete with cogongrass. It has very low value for wildlife
because of its rough edges and high silica content. Stands of
cogongrass are
nearly impenetrable. Cogongrass is fire-tolerant, and disrupts
both natural and prescribed fire regimes. The US Forest Service
and many other organizations are committed to eradicating cogongrass in
the
Francis Marion National Forest. Please help by reporting any
sighting of this noxious weed to Dr. Jean Everett at everettj@cofc.edu or
843-953-7843. Sightings should also be reported to the Department of Plant Industry at Clemson
and to your local Cooperative
Extension Office. Even if the plant is on private land,
please report
it so that we can contact the landowner and offer assistance in
eradication. Click
