Tree ecophysiology in dryland riparian ecosystems | Desert Botanical Garden


Riparian forests are among the most threatened in North America as a consequence of altered hydrological conditions, invasive species and climate change. The Dryland Plant Ecophysiology Lab seeks to identify tree ecophysiological traits that underlie adaptation to heat waves, drought, herbivory and other stressors. Along with collaborators at Northern Arizona University, the research is providing critical information for practitioners to restore and conserve dryland riparian forests under current and future environmental conditions.
