DescriptionWe studied seasonal courses of soil water utilization in a 450-year-old Pseudotsuga menziesii/Tsuga heterophylla forest. Mean root area in the upper 60 cm of soil was significantly greater in the vicinity of T. heterophylla trees. However, seasonal water extraction on a root area basis was significantly greater near P. menziesii trees at all depths between 20 and 60 cm, leading to significantly lower water storage in the upper 60 cm of soil near P. menziesii trees at the end of the summer dry season. The results provide information on functional traits relevant for understanding the ecological distributions of the two species and have implications for spatial variability of processes such as soil respiration and nutrient cycling.
