This report presents statewide risk maps and priority management recommendations for 43 invasive plant species selected to be of special importance for the Sierra Nevada region of California. Maps include current distribution, suitable range in 2010, and projected suitable range for 2050. Recommendations include priority eradication, containment, and surveillance opportunities for each Weed Management Area in the region.
These results support effective conservation planning, addressing a top ecological stressor as part of climate change adaptation strategies. The results can help natural resource managers make a strong case for funding, and provide a foundation for enhancing regional collaboration.
