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. <ulink url="https://doi.org/10.1890/141889.1">https://doi.org/10.1890/141889.1</ulink> Kattge, J. et al, 2020.

The HBES is a collaborative effort at the Hubbard Brook Experimental Forest, which is operated and maintained by the USDA Forest Service, Northern Research Station.
