Management Briefs are what we at NW RISCC call our fact sheets, and what other RISCC networks call "Management Challenges" or "Research to Practice" documents. Call them what you want, these documents pull together relevant information from multiple sources to provide a broader, more applied perspective on issues at the intersection at climate change and invasive species.
In September 2023, invasive quagga mussel larvae were detected in the Columbia River Basin, the last major North American river basin without an established population. The presence of these and other invasive mussel species such as zebra and golden mussels poses a direct threat to sensitive ecosystems, local economies, and cultural resources. Warming waters and other climate factors may facilitate the expansion of suitable habitats for these species. In turn, the impacts of established invasive mussels could worsen the climate challenges already being faced in the Northwest.
The European green crab has received significant attention for its known and potential economic, cultural, and ecological impacts in the Northwest and beyond. This Management Brief compiles information on the ways warming temperatures can influence this ongoing invasion and highlights the role climate adaptation can play in management.
In June 2022, the emerald ash borer (Agrilus planipennis; “EAB”) was discovered in Forest Grove, OR, marking its first appearance west of the Rocky Mountains. Forest managers fear for the future of Oregon ash (Fraxinus latifolia) and at least 8 other tree species found only in western North America. Climate change may broaden the threat of EAB invasion and will require climate-smart, proactive management to sustain healthy forests.
