When Climate Change and Invasive Species Intersect:
Wednesday, July 1, 2020 from 12:00 – 1:30 PM HST
Virtually on GoTo Meeting Webinar
12:00 – 12:30: Quantifying the impacts of land-cover change and climate variability on freshwater resources in the state of Hawai‘i
Alan Mair, USGS Pacific Islands Water Science Center
12:30 – 1:00: How do invasive plants affect evapotranspiration and cloud water interception in Hawai‘i?
Tom Giambelluca, UH Water Resources Research Center
1:00 – 1:30: Question & Answer
How does water availability on our landscape interplay with invasive species and climate variability?
To answer this question, the July Pacific RISCC webinar featured presentations by Alan Mair from the Pacific Islands Water Science Center and Tom Giambelluca from the UH Mānoa Water Resources Research Center. Alan Mair talked about the combined hydrological impacts of non-native forest species and climate variability on groundwater recharge and how it will affect freshwater availability. While, Tom Giambelluca took us on a technical journal through his research in measuring and monitoring evapotranspiration and transpiration of invaded landscapes to understand how invasion impacts the water cycle.
