Coarse woody debris (CWD) biomass was measured and mapped in burned, clearcut, and intact lodgepole pine forests in two areas of the Rocky Mountains of Wyoming: the Medicine Bow National Forest (MBNF) and Yellowstone National Park (YNP). In addition, the amount of CWD consumed or converted to charcoal by fire was estimated in a recently burned stand in YNP. A spatially explicit simulation model...
During the early 1900s, nearly 37 million hectares of land in Southern United States were under longleaf pine ( Pinus palustris ) relative to current area 1.6 hectares. This study compares economics southern pines (longleaf, loblolly taeda ), and slash elliottii )) facilitate decision making family forest landowners design suitable financial incentives for increasing region. We simulated six gr...
The impact of weed control and fertili7Mion on incnajed tree growth is positive and significant but the effects on wood pmper6es are not well known. lncrernent axes mn, coUac@d from lobldly pine (pinus faeda L) trees growing on an existing site-preparation experiment in the lower Piedmont of Georgia at age 15. The levels of site praparation were: ldearcut only; P-chainsaw, 3-shear and chop; 4-s...
Land use and fire exclusion have influenced ecosystems worldwide, resulting in alternative ecosystem states. Here, I provide two examples from the southeastern United States of fire-dependent open pine pine-oak forest loss examine dynamics replacement forests, given continued long-term declines foundation longleaf (Pinus palustris) shortleaf echinata) pines recent increases commercial loblolly ...
Crown and canopy structurecorrelate with growth efficiency and also determine stem size and taper as described by the uniform stress principle of stem formation. A regression model was derived from this principle that expresses basal area increment in terms of the amount and vertical distribution of leaf area and change in these variables during a growth period. This model was fit t o data coll...
