Threat of Invasives to Native Species and Ecosystems

Science Center Objects

Invasive species are a growing threat to native species and ecosystem processes in fresh waters. The Introducing non-native fish into an area may have no effect, little current effect, or the potential to seriously impact the native species, possibly resulting in their extinction. We conduct research to address the causes of invasions and their impacts. We also provide technical support for resources managers seeking effective solutions for invasive species. Our focus has been on nonnative salmonids, especially brook trout (Salvenlinus fontinalis) in the western United States, but also on invasive salmon and trout in South America and carp in southeastern Oregon.
