Current Projects

Freshwater systems are vulnerable to the effects of multiple stressors and the combined influences of species invasions, climate change, and management actions are important to understand.

In collaboration with partners at the University of Washington (UW), CEG developed a simulation model to characterize aquatic invasion dynamics. We built a spatially explicit, individual-based model to simulate interactions between Smallmouth bass (Micropterus dolomieu) and Rusty crayfish (Faxonius rusticus) in a major tributary to the Columbia River. UW and CEG are simulating the effectiveness of management strategies in slowing or containing the spread of both invasions to support Chinook salmon and Steelhead populations.
