A cross volume of 1 billion cubic feet of red alder exists on about 350,000 acres of British Columbia forest land that could produce much higher values if stocked with Douglas-fir or black cottonwood. However, the characteristically rapid juvenile growth of alder from seed, which permits full stocking at early ages, may prove valuable for management of alder on very short rotations, Data are presented on radial growth and important tree characteristics for open- and forest-grown trees. Regressions of crown width on dbh and a yield table based on these are included. It is shown that crown width and root spread are highly correlated. Several total cubic-foot tree volume equations are given, and it is noted that one of these, V/b=0.44H, also can be used to estimate growth and yield per acre. Merchantable volume factors and reductions for decay, waste, and breakage are summarized. Distributions of section volumes and diameters inside bark are described by regression equations. Data on bark thickness and percentage are summarized.
