Fig. 6. Whole-tree loss of hydraulic conductance (left panels) and relative transpiration (right panels) at the full canopy stage versus relative extractable water (REW) for both
either a natural hardwood forest (open circles) or a pine plantation (filled circles) growing either in the coastal or the Piedmont region of North Carolina, USA. The inserts
magnify the loss in tree conductance and relative transpiration between 0.02 and 0.3 REW
