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.

Pilot Testing and Protocol Development of Apple Snail Suppression at Mandalay National Wildlife Refuge

The maculata apple snail (Pomacea maculata) has invaded many coastal and some inland areas in south Louisiana. Reports have indicated that the freshwater snails have significantly reduced the amount of submerged aquatic vegetation (SAV) and floating leaved vegetation (FLV) available for waterfowl and other wildlife.

Developing Techniques for Estimating Nutria (Myocastor coypus) Abundance

Nutrias (Myocastor coypus) are an aquatic rodent imported from South America to the United States in the 1920-40’s for the fur farms. Since their original importation they have become established in the wild in many regions of the United States.

Statistical Models for the Design and Analysis of Environmental DNA (eDNA) Surveys of Invasive and Imperiled Species

Detecting invasive species at low densities or prior to population establishment is critical for successful control and eradication. For example, Burmese pythons occupy thousands of square kilometers of mostly inaccessible habitats.
