Establishing new species in cogongrass-infested areas is difficult because cogongrass secretes allelophathic chemicals, has an extensive system of rhizomes, and creates a dense canopy. This work has established the potential utility of replacing invasive plants with other species. However, most restorationists would prefer the use of native species. We have therefore begun studies to evaluate whether similar practices will encourage the establishment and growth of native species. We expect that native plants will be more difficult and costly to work with, therefore research continues to develop more cost-effective methods.
Coordination is essential in dealing with the problem of invasive plants.
Conservation organizations and state agencies must develop a regional strategy to discourage the spread of cogongrass while restorationists and others begin the work of suppressing this nuisance species. IFAS now has an Invasive Plant Task Force that is developing an action plan to determine the most effective role that our organization can play in dealing with cogongrass and other noxious non-native plant species. The Departments of Environmental Protection and Agricultural and Consumer Services are presently developing the framework for an interdepartmental agency responsible for coordinating the management of invasive plants in Florida. IFAS will play a key role in this partnership by providing assistance with research and outreach efforts. These initiatives will help Florida to deal more effectively with invasive plant problems in the future, thereby protecting public land ecosystems.
