Bird abundances have been determined from timed
censuses, territory maps and nest locations at the Hubbard
Brook Experimental Forest from 1969 to the present. This data
set includes counts of the number of adult birds (males and
females) per 10 ha at HBEF (1969 - present) and on three
additional plots within the White Mountain National Forest
(1986 - 2000).
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.
