|Biosphere Reserve Information|
The Hubbard Brook Biosphere Reserve and Experimental Forest is located in the White Mountain National Forest near Woodstock (New Hampshire). The biosphere reserve is mainly dedicated to the long-term study of forest and associated aquatic ecosystems.
The biosphere reserve is entirely forested, mainly with deciduous northern hardwoods. Logging operations ending around 1915-1917 removed large portions of the conifers and better quality, accessible hardwoods. The present second-growth forest is even-aged and composed of about 80 to 90% hardwoods and 10 to 20% conifers. Trees on the lower and middle slopes include sugar maple (Acer saccharum), beech (Fagus grandifolia), and yellow birch (Betula alleghaniensis), and some white ash (Fraxinus americana). Red spruce (Picea rubens), balsam fir (Abies balsamea), and white birch (Betula papyrifera var. cordifolia) are abundant at higher elevations and on rock outcrops.
In 1988, the area was designated as a Long-Term Ecological Research (LTER) site by the National Science Foundation. On-going cooperative efforts among diverse educational institutions, private institutions, government agencies, foundations and corporations have resulted in one of the most extensive and longest continuous databases on the hydrology, biology, geology and chemistry of natural ecosystems.
