Post-fire forest regeneration and restoration under climate change: insight from natural and managed settings

Register.

This webinar examines how post-fire weather and climate can influence tree recruitment by surveying regenerating vegetation 4-8 years after 14 different wildfires that burned between 2004 and 2012, a period  that captured a wide range of post-fire weather conditions. A consistent but weak effect of post-fire drought reduced regeneration of conifers, especially shade-tolerant species, supporting model-based projections that shrub and hardwood species will increase in dominance as drought becomes more common. However, post-fire recruitment patterns were also strongly related to long-term climate and adult tree species abundance, suggesting that “biological legacies” may constrain post-disturbance recovery outcomes and may limit the ability of forests to naturally track changes in climate.
