Invasive Species

USGS WARC science focuses on better understanding invasive species' biology and ecology and their potential for negative ecological, economic, or health impacts. WARC implements innovative approaches to help monitor the spread of invasive or non-native species, develop new methods and technologies to better detect such species, and assess their impact to the native ecosystems they have invaded.

Integrating Science and Management for Optimal Prevention and Control of Invasive Nymphoides in Florida

Two invasive species of floating hearts, Nymphoides cristata and N. indica, are actively managed in Florida. A rare native species, N. humboldtiana, has been found in Florida and verified by molecular methods; this species is nearly indistinguishable from N. indica.

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.

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.
