- Observation In the upper crown, one-year foliage increased acropetally from 52 to 75%.
- Observation Upper-crown two-year foliage decreased slightly from 28 to 22%.
- Observation Upper-crown three-year-and-older foliage decreased markedly from 20 to 3%.
- Observation One- and two-year leaves averaged 73% of total crown leaf biomass across thinning regimes.
- Intervention effect Stand density had little effect on foliage proportion by crown position or age.
- Observation Foliage biomass ranged from 4.9 to 11.3 tonnes/ha over the observed stand densities.
- Observation Annual foliage production ranged from 2.4 to 4.3 tonnes/ha.
