The U.S. Department of Agricultureâs (USDA) Forest Service (FS) invasive species program is to reduce, minimize, or eliminate the potential for introduction, establishment, spread, and impact of invasive species across all landscapes and ownerships. Invasive species have been characterized as a âcatastrophic wildfire in slow motion.â Thousands of non-native invasive plants, insects, fish, mollusks, crustaceans, pathogens, mammals, birds, reptiles, and amphibians have infested hundreds of millions of acres of land and water across the Nation, causing massive disruptions in ecosystem function, reducing biodiversity, and degrading ecosystem health in our Nationâs forests, prairies, mountains, wetlands, rivers, and oceans. Invasive organisms affect the health of not only the Nationâs forests and rangelands but also of wildlife, livestock, fish, and humans. A washing station has been set up to allow visitors at the National Bison Range Wildlife Refuge in Montana to clean the underside and wheel-wells of their vehicles to prevent the spread of non-native weeds and grasses on November 17, 2007.
