Webinar information

Assisted migration of Coastal Douglas-fir (Pseudotsuga menziesii, PSME) is increasingly used to introduce populations adapted to future heat and drought conditions into historically cooler regions. However, successful seed transfer must also account for current environmental constraints, particularly low temperature extremes that affect trees during the vulnerable establishment phase. In addition, drought is projected to intensify across the western United States, interacting with temperature stress, making it critical to evaluate tolerance to multiple stressors when selecting seed sources.

This webinar highlights new research which characterizes temperature and drought related traits across the native U.S. range of PSME to evaluate population suitability for assisted migration. Physiological, phenological, and morphological traits were measured in 23 populations (18 wild-collected and 5 orchard sources) in nursery trials and common garden field trials in Washington. Cold hardiness was quantified using controlled freeze tests and electrolyte leakage, budburst phenology was monitored weekly, and high-temperature thermotolerance was assessed to determine population-specific phenology and critical temperatures. Multivariate analyses linking these traits with provenance climate variables are used to identify climatic drivers of stress tolerance and potential trade-offs among traits.
