Hubbard Brook Experimental Forest: Tree component masses sampled west of watershed 6 by Whittaker et al in 1965

In the summer of 1965, Whittaker et al. sampled 93 trees west of
watershed 6 at the Hubbard Brook Experimental Forest. Allometric
equations modeling the biomass of various components in relation to
diameter and height were published in 1974 in Ecological
Monographs , and form the basis for most subsequent biomass
estimates at Hubbard Brook and in many other northeastern locations.
The data posted here are oven-dry biomass data by component by tree. These Hubbard Brook allometry data have been included in the following
two larger allometry databases: Falster, D.S. et al, 2015. BAAD: a Biomass And Allometry Database for
woody plants. Ecology 96, 1445.
