资源简介：
Forest inventory surveys were initiated in 1965,
repeated in 1977, and repeated at 5 year intervals after
that. This is the initial data set and was collected in
summer of 1965. The inventory consists of a total inventory
of all trees >= 1.5 cm diameter-at-breast-height (dbh) on
the whole of the watershed (13.23 ha), as measured in each of
the 208 25 m x 25 m plots. Shrubs, seedlings and small
saplings were also surveyed.
These data were gathered as part of the Hubbard Brook
Ecosystem Study (HBES). 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.
