Wildlife Invaders: Managing Invasive Species in Oregon

With Catherine de Rivera, PhD, Professor of Environmental Science and Management at Portland State University

From cane toad to snakehead to the vine that ate The South, invasive species can capture the imagination and can cause all sorts of problems. Here in Oregon, we have our own menagerie of invaders impacting the state: Paterson’s curse, Sudden oak death, green crabs, gypsy moths, and feral swine, to name a few. But the issue of invasive species is nuanced and management is not always straightforward and embraced.


In this talk, ecologist Catherine de Rivera, will share stories about and the science behind some of our problematic invasive species.  She will also dive into key issues and complications Oregon faces in invasive species management, but also the effective solutions we know, some of which include you.


Catherine de Rivera, PhD, a professor at Portland State University, researches the spread and impacts of invading marine species, such as the European green crab, and how best to manage them. She is especially interested in the role of predator-prey relationships involving non-native species. She teaches courses in the ecology and management of biological invasions, science communication, and environmental problem solving. She is the current vice-chair of the Oregon Invasive Species Council. Invasive species are on the negative side of connecting habitats; on the flip side, she is also interested in the benefits of connecting habitats more locally for wildlife. In this vein, she researches benefits of and approaches to species movement across Oregon’s landscape, serves as a steering committee member of the intertwine-wide Regional Habitat Connectivity Working Group, and works on the Oregon Connectivity and Mapping Project.
