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 is investigating the dynamics between multi-species invasions and climate change. The team is using 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 forecasting the growth and spread of the bass and crayfish populations under different climate scenarios. We are also simulating the effectiveness of management strategies in slowing or containing the spread of both invasions to support Chinook salmon and Steelhead populations.
