In order to better understand the role that forest ecosystems play in the
global carbon budget, it is necessary to understand the dynamics of biomass
accumulation and change arising from anthropogenic and natural disturbances.
Presented here are the results of study across a broad spatial (1050ha) and
temporal (>70 years) scale for the Bartlett Experimental Forest, a northern
temperate hardwood forest, located in the White Mountain National Forest, New
Hampshire,USA
Permanent plot forest inventory data converted to biomass were analyzed
using a mixed linear model to determine the influence of local environmental
variables on aboveground biomass accumulation through time for managed and
unmanaged stands. Stand age was the primary determinate of standing
biomass, followed by stand-origin (all-age, even-age), habitat, and forest cover
type. Managed and unmanaged stands achieved similar levels of standing
biomass over time (>210 Mt/ha), and biomass continues to increase and is
higher than regionally reported.
