Effects of nonindigenous invasive species on water quality and quantity

Publications Posted on: August 11, 2010
Physical and biological disruptions of aquatic systems caused by invasive species alter water quantity and water quality. Recent evidence suggests that water is a vector for the spread of Sudden Oak Death disease and Port-Orfordcedar root disease. Since the 1990s, the public has become increasingly aware of the presence of invasive species in the Nation’s waters.

The role of the Forest Service in aquatic invasive species research

Publications Posted on: August 11, 2010
Aquatic ecosystems include the most imperiled taxa in the United States, and invasive species are the second leading contributor to this imperilment. The U.S. Department of Agriculture (USDA), Forest Service is legally mandated to sustainably manage aquatic habitats and native species on National Forest System (NFS) lands.

Terrestrial animals as invasive species and as species at risk from invasions

Publications Posted on: August 11, 2010
Including terrestrial animal species in the invasive species strategy plan is an important step in invasive species management. Invasions by nonindigenous species threaten nearly 50 percent of imperiled native species in the United States and are the Nation's second leading cause of species endangerment.

Invasive forest pathogens: Summary of issues, critical needs, and future goals for Forest Service Research and Development

Publications Posted on: August 11, 2010
Invasive pathogens have caused immeasurable ecological and economic damage to forest ecosystems. Damage will undoubtedly increase over time due to increased introductions and evolution of invasive pathogens in concert with complex environmental disturbances, such as climate change. Forest Service Research and Development must fulfill critical roles and responsibilities to address issues related to invasive forest pathogens.
