Environmental thresholds for drought- and heat-related tree mortality

CORDIS · observation · Publication date unknown

o uncover environmental thresholds and key environmental drivers of drought- and heat-related tree mortality at the species-level for various forest biomes. Use of state-of-the-art remote sensing and deep learning methods allows me to capture where, when and what kind of trees (species, structure) have died for tens of millions of trees to increase our understanding of spatial and temporal tree mortality patterns. My approach uses laser scanning data to provide detailed tree 3D characterization and calculation of tree position within tree community (competition) and the landscape (water availability, microclimate). Then, combining these variables with information on tree xylem vulnerability, pest insects, soil temperature and climate, we can ultimately reveal species-specific environmental thresholds and key drivers of drought- and heat-related tree mortality. This research will open new horizons, bringing ecophysiology, remote sensing, forest ecology and entomology together, and developing methods to quantify drivers of tree mortality in much greater depth than has been possible to
