There is growing concern that changing climate conditions will amplify the negative impacts of non-native invasive species and facilitate their expansion. Despite the potential ecological and economic impacts of invasive species expansions in the Northwest, there has been no comprehensive synthesis on climate change effects on invasive species – until now. NW CASC-funded researchers Jennifer Gervais (Oregon Wildlife Institute), Clint Muhlfeld (U.S. Geological Survey) and colleagues conducted an extensive literature analysis to determine the current state of knowledge about climate change effects on non-native invasive species in the Northwest.

Interactions between invasive species and climate change present new challenges for resource management. Prior to a new study by NE CASC fellow Evelyn Beaury and her collaborators, however, it was unclear what the common concerns, strategies, limitations, and research needs were for managing invasive species in a changing climate. In their nationwide survey of invasive species managers from government, non-profit, and private organizations, Beaury's team found that while the majority of managers are very concerned about the influence of climate change on invasive species management, the organizations they represent are typically far less engaged with this issue. This study illustrates that the complicating challenge of climate change may open a new avenue for elevating the efficiency and success of current invasive species management efforts if a collaborative approach is adopted in this area.
