  • When Climate Change and Invasive Species Intersect: Identifying Fire-Promoting Invasive Plants and Their Potential to Impact Hawai`i’s Natural & Cultural Resources

    • Mar 22, 2022

    • Pacific Islands Climate Adaption Science Center.

    • Across the Pacific, wildfire poses a major threat to biological and cultural resources, and the threat is only predicted to become larger with climate change. In this talk, graduate students Kevin Faccenda and Kelsey Brock discuss a new tool and methodology for predicting the fire risk of invasive species before they enter a region so that management efforts can be focused on the highest risk incipient species.

      This tool uses data collected from the primary literature as well as a machine learning model trained on expert survey data to predict fire risk. Their team examined this risk in a spatial context by modeling the distribution of multiple invasive plants and climatic conditions that promote wildfire across the main Hawaiian Islands. Models were created based on current-day climate conditions as well potential conditions at the end of the century to under climate change.
