Abstract:
HFR002:
Three forested tracts, comprising a total of 1,200 ha, are sampled
every 10-30 years. Stand boundaries are located by ground survey
(1936) or aerial photography (1946 and later). Each stand is sampled
(sampling technique varies), noting tree species, DBH class, height
class, canopy class, form, and condition. This data is best suited for
studying large-scale changes in the forest.
The
... Harvard Forest LTER site (HFR) is primarily Eastern deciduous
forest. Research topics include: long-term climate change; disturbance
history and vegetation dynamics; comparison of community, population,
and plant architechtural responses to human and natural disturbances;
forest-atmosphere trace gas fluxes; organic matter accumulation,
decomposition and mineralization; element cycling, fine root dynamics
and forest microbiology.
