Plant, animal, or microbe species that is non-native (or alien) to the ecosystem under consideration and whose introduction causes or is likely to cause economic or environmental harm, or harm to human health.
Snakeheads, aggressive airbreathing freshwater fishes that are not native to North America, are considered injurious to certain native North American fish and other aquatic wildlife.
This program provides management-oriented research and delivers information needed to prevent, detect, control, and eradicate invasive species, and to restore impaired ecosystems.
Links to research projects that will improve the ability to detect, monitor, and predict the effects of invasive species, including exotic animals, on native ecosystems of the Pacific Southwest (California, Nevada, Utah, and Arizona).
List and brief abstracts on research projects on invasive species, the ecology of introduced species, and developing management strategies at Patuxent Wildlife Research Center.
Describes investigative techniques focused on genetic characteristics of individuals and populations, and explains how this information helps improve existing natural populations and potentially impede invasive populations.
