a Leaf area/sapwood area (in per square meter per centimeter) and b specific conductivity (k s) and c leaf-specific conductivity (LSC) by vertical position in the tree for mature and young Douglas-fir trees (each point shows mean ± s.e. for n = 5–6 samples). The March harvest was before current year’s growth had started, and the September harvest was near the end of current year’s growth. The two young stands were adjacent to one another
