Investigation of 52 trees suggests that foliage mass (kg dry weight) of individual Douglas-fir, noble fir, and ponderosa pine trees can be estimated from regressions on sapwood cross-sectional area (cm²) at dbh (1.3m). Equations are respectively y = 0.072 X -1.34, y = 0.51 X -4.63, and y = 0.043 X +7.13. Correlation coefficients (r) were 0.98 or greater. Similar relations may exist for other species having clearly defined sapwood. Forest Sci. 20:205-206.
