Net primary production and phenology on a Southern Appalachian watershed. [pdf]Paper  abstract   bibtex   
The major objective of the study was to measure above-ground net primary production (NPP) seasonally and relate it to phenological activity in a hardwood forest at Coweeta. NPP was estimated as the increase in biomass, estimated from regression equations on diameter. Diameter increases were measured by vernier tree bands. Phenological observations were made on bud break, leaf emergence, flowering, mature fruit, leaf senescence, and leaf fall. The species studied intensively were Acer rubrum, Quercus prinus, Carya glabra, Cornus florida, and Liriodendron tulipifera.
