Invasive Species

More than 6,500 nonindigenous species are now established in the United States, posing risks to native species, valued ecosystems, and human and wildlife health. These invaders extract a huge cost. The current annual environmental, economic, and health-related costs of invasive species exceed those of all other natural disasters combined.
CERC is actively conducting research and monitoring on established Asian carp populations, exotic plant species along horse trails in the Missouri Ozarks, and invasive grass species on the coastal plains of Texas.
