- Association Sapwood area correlated strongly with balsam fir foliage mass.
- Method / resource Breast-height sapwood predicted balsam fir foliage mass with R = 0.978.
- Method / resource Breast-height sapwood predicted balsam fir projected leaf area with R = 0.952.
- Method / resource Breast-height sapwood predicted red spruce foliage mass with R = 0.914.
- Method / resource Breast-height sapwood predicted red spruce projected leaf area with R = 0.934.
- Method / resource Regressions improved when sapwood area was measured at the base of the live crown.
- Association The balsam fir sapwood–foliage relationship was similar across three contrasting sites.
- Method / resource Foliage area can be predicted from increment cores with high certainty across stand conditions and tree vigor.
