National Center for Research on Aquatic Invasive Species GLERL hosts NOAA's National Center for Research on Aquatic Invasive Species (NCRAIS) at its Ann Arbor facility. The center will allow NOAA to more effectively organize and coordinate its aquatic invasive species research efforts while ensuring that NOAA resources are focused on nationwide priorities.

![]() Program Background The Great Lakes basin is the aquatic gateway to the heartland of America and a national hot spot for aquatic invasive species (AIS) introductions that can reach other sections of the U.S. Records of aquatic species invasions in the Great Lakes start in the early 1800s. By 2005 at least 182 AIS have been reported in the Great Lakes, with more than 40% discovered since 1960. The rate of discovery since 1960 has not been linear, but for illustrative purposes, can be said to average about one new invader every 28 weeks. Nonindigenous species are now a significant component of most trophic levels in the Great Lakes. GLERL's research on invasive species targets two key issues: 1) The prevention of new invasive species introductions and 2) The understanding of the biological and ecological impacts of nonindigenous species in the Great Lakes.
