Fall Rates of Prescribed Fire-Killed Ponderosa Pine

摘要

Fall rates of prescribed fire-killed ponderosa pine were evaluated relative totree and fire damage characteristics. High crown scorch and short survival time after fire injury were factors leading to a high probability of early tree fall. The role of chemical defense mechanisms is discussed. Results apply to prescribed-fire injured, second-growth ponderosa pine less than 16 inches diameter at breast height.
