Invasive Species

Research, monitoring, and technology development for containment or eradication of non-indigenous species that have potential to cause significant ecologic or economic damage and those that impact human health. Scientists test and develop methods to better detect invasive species, determine the likelihood of their spread and impact, report distribution to track their spread, methods to contain and control harmful invasive species, as well as means to restore ecosystems after control efforts. Recent emphasis has been on using advanced technologies such as remote sensing and genetics methods to develop species-specific detection and control tools for terrestrial and aquatic species, with recent focus on Asian carp, sea lamprey, and snakes. Includes studies on ecologic impacts, invasion biology, and basic life history to help determine risk and develop control strategies.
