Other claims from this paper (9)

Intervention effect Total tree and bole wood biomass in thinned plots converged toward unthinned plots.
Intervention effect At site one, 70% stocking exceeded unthinned biomass after 16 years.
Association Heavily thinned stands may take longer to converge in biomass.
Association Foliage and bark biomass fell as thinning intensity rose.
Intervention effect Thinning significantly affected the biomass proportions in branches and bark.
Intervention effect Except for heavy thinning, thinning did not significantly affect bole allocation proportion.
Intervention effect Heavy thinning appeared to increase foliage fraction, without statistical significance.
Association Better sites allocated more biomass to bole wood.
Association Better sites allocated less biomass to foliage.
