Invasive Species Program
Home
More than 6,500 nonindigenous species are now established in the United States, posing risks to native plants, animals, microorganisms, valued ecosystems, and human and wildlife health. In fact, the current annual environmental, economic, and health-related costs of invasive species exceed those of all other natural disasters combined.
Nonindigenous Aquatic Species (NAS) Database
The NAS database is a central repository for spatially referenced biogeographic accounts of introduced aquatic species. The program provides scientific reports, online/realtime queries, spatial data sets, distribution maps, and general in

Invasive Zebra Mussels Found in Pet Stores in 21 States
A citizen’s report of an invasive zebra mussel found in an aquarium moss package found in a pet store prompted a U.S. Geological Survey expert on invasive aquatic species to trigger nationwide alerts that have led to the discovery of the destructive shellfish in pet stores in at least 21 states from Alaska to Florida.

Satellite-tagged osprey nearly sets longevity record and productivity response to initial captures
We equipped adult Ospreys (Pandion haliaetus) from 24 nests in Oregon/Washington with satellite-tracked battery-powered radios, known as platform transmitter terminals (PTTs), in 1996–1999. These Ospreys from the lower Columbia River (river miles 76–286), and the Willamette Valley in western Oregon were part of a larger study of Osprey fall...
Henny, Charles J.; Martell, Mark S. Veligers of the invasive Asian clam Corbicula fluminea in the Columbia River Basin: Broadscale distribution, abundance, and ecological associations
The invasive Asian clam Corbicula fluminea was introduced to North America in the 1930s and now inhabits most regions of the conterminous United States; however, the distribution and ecology of C. fluminea in the Columbia River Basin is poorly understood. During 2013 and 2014, 5 Columbia-Snake River reservoirs were sampled monthly from May through...
Hassett, Whitney; Bollens, Stephen M.; Counihan, Timothy D.; Rollwagen-Bollens, Gretchen; Zimmerman, Julie; Emerson, Joshua E. Early detection monitoring for larval dreissenid mussels: How much plankton sampling is enough?
The development of quagga and zebra mussel (dreissenids) monitoring programs in the Pacific Northwest provides a unique opportunity to evaluate a regional invasive species detection effort early in its development. Recent studies suggest that the ecological and economic costs of a dreissenid infestation in the Pacific Northwest of the USA would be...
