Short summary

We investigated the role of water availability in shaping forest carbon cycling and conifer morphological traits in the Cascade Mountains, Oregon, a region that is expected to become warmer and drier in the coming century. Forest leaf area, productivity, and biomass were strongly related to mean annual water availability. Across the hydroclimatic gradient, trees exhibited interspecific variation in traits that balanced maintaining hydraulic function against the need to compete for light.
