Controlling the spread of invasive plants: a national effort one-day symposiu...( al parks and are a major threat to our ...)

al parks and are a major threat to our nations wildlife refuges and national forests. In response, The National Park Service, National Wildlife Refuge System and the U.S. Forest Service have developed plans to prevent, detect and rapidly respond to invasions of non-native plants. These plans include the establishment of Exotic Plant Management Teams (EPMT) by the National Park Service. Modeled after the approach used in wildland fire fighting, these teams provide highly trained, mobile strike forces of plant management specialists who assist in the control of exotic plants. The success of these efforts and the challenges that remain will be discussed in three presentations during this symposium (AGRO 87, AGRO 88, AGRO 90, Tuesday, Aug. 30, 1:05 p.m.; 1:25 p.m.; and 2:05 p.m.)

Even the giant Gila monster wasnt this nasty Introduced from Eurasia in about 1917, the giant hogweed is not only an environmental hazard, but poses a public health threat as well. Exposure to its clear, watery sap can cause severe skin irritation, swelling and blisters that can last for several months. Contact with the eyes can lead to temporary or, in some cases, permanent blindness. A survey and eradication program is underway in western Pennsylvania and the USDA Animal & Plant Health Inspection Service is encouraging a coordinated effort to eliminate the plant, which can reach heights of 15 to 20 feet, throughout the Northeast. (AGRO 91, Tuesday, Aug. 30, 2:25 p.m.)

Sometimes they come back, but not if we can help it A local success story, the Anacostia Watershed Society a non-profit environmental organization dedicated to restoring and protecting the Anacostia River has developed a program to eliminate a dozen non-native plants from the watershed. Using a combination of mechanical controls and a minimal amount of chemicals, the Society hopes to rescue the native ecosystem from these invasive pla
