U.S. Army Corps of Engineers Invasive Species Efforts [Updated January 4, 2021]   [open pdf - 484KB]

From the Document: "An 'invasive species' is a nonnative species that does or is likely to cause economic or environmental harm or harm to human health. Invasive species impact terrestrial and aquatic--including marine and freshwater--systems. As society has become more connected, opportunities for the spread of invasive species have increased (e.g., navigation activities can transport species and introduce them to multiple different watersheds and waterbodies).After introduction, invasive species may become established and spread;it can be costly and difficult (or impossible, in some cases) to control or eradicate them. Many federal and nonfederal agencies managing land and water undertake efforts to prevent the introduction and spread of invasive species or, upon detection of an invasive species, devote resources to control and eradication efforts. [...] The U.S. Army Corps of Engineers (USACE), part of the Department of Defense, develops and maintains civil works projects in the United States principally to improve navigable channels, reduce flood and storm damage, and restore aquatic ecosystems. USACE is the steward of approximately 12 million acres of public lands and waters at hundreds of water resources projects nationwide. Invasive species can impact USACE projects by outcompeting native species, clogging water pipes, and affecting water quality and recreation. [...] This In Focus presents information on USACE invasive species funding and selected authorities, programs, and projects, as well as related legislative action in the 116th Congress."
