Forest Response to Severe Drought: Do restoration thinning treatments in coast redwood-Douglas fir forests increase resiliency to drought?

Coast redwood-Douglas-fir forest hold important economic, ecological, and cultural values which will likely be threatened by changing climate and increased drought stress. Restoration thinning has been used by forest managers with the goals of decreasing stand competition and accelerating maturation to old-growth conditions. However, uncertainty still remains on whether restoration treatments provide forests with increased resiliency to disturbances such as severe drought. The aim of this research is to investigate the effectiveness of different restoration treatments in improving second-growth forest resiliency to drought stress in coast redwood-Douglas-fir forests of Redwood National Park.
