Southwestern ponderosa forest structure and resource conditions: changes since Euro-American settlement
Covington WW and Moore MM. 1994. Southwestern ponderosa forest structure and resource conditions: changes since Euro-American settlement. Journal of Forestry. 92(1):39-47
The ponderosa pine (Pinus ponderosa) forests of the American Southwest have changed composition and size due to heavy grazing, logging, and fire exclusion in conjunction with climatic oscillation and elevated atmospheric carbion dioxide. There are more younger and smaller trees; fewer older and larger trees; an accumulation of heavy forst floor fuel loads; reduced herbaceous production; and associated shifts in ecosystem structure, fire hazard, and wildlife habitat.
