Description: We incorporated soil/plant biophysical properties into a simple model to predict seasonal trajectories of hydraulic redistribution (HR). We measured soil water content, water potential root conductivity, and climate across multiple years in two old-growth coniferous forests. The HR variability within sites (0 to 0.5 mm/d) was linked to spatial patterns of roots, soil moisture, and climate. The HR seasonally accounted for up to 9 percent of daily water use, peaking at 0.16 mm/d (ponderosa pine) or 0.30 mm/d(Douglas-fir), then declining as modeled pathway conductance dropped with increasing root cavitation. Patterns of HR were attributed to variability in water potential gradients and conductivity within the root system.

Keywords: Douglas-fir (Pseudotsuga menziesii), hydraulic lift, hydraulic redistribution, ponderosa pine (Pinus ponderosa), root conductivity, soil water content, water potential
