Cogongrass is a growing threat as it continues its rapid spread across the Southeast, reducing forest and pasture productivity, destroying wildlife habitat, impacting rights of ways and presenting an extreme fire hazard.

The purpose of this conference is to convey the latest understanding in restoring lands, managing, controlling and eradicating cogongrass, and to explore existing and needed networks for coordinating strategies for successful cogongrass management.
