Fuel Dynamics In Southern Pine Beetle-Killed Stands And Their Implication To Fire Behavior, Jennifer Evans
Fuel Dynamics In Southern Pine Beetle-Killed Stands And Their Implication To Fire Behavior, Jennifer Evans
All Theses
The increase in both southern pine beetle (SPB) (Dendroctonus frontalis Zimm) outbreak and wildfire occurrence in recent decades has resulted in a growing concern regarding possible interactions. Few studies have quantified fuel characteristics of SPB-killed stands, and none has studied the dynamics of this fuel complex over time. Moreover, how changes in these fuels affect fire behavior remains unknown. To address this lack of empirical data, field measurements and modeling were combined to study fuel dynamics and potential fire behavior within control and post-outbreak loblolly pine-dominated forest stands across a chronosequence ranging from 0 to 8 years since outbreak. Fuels …

Heavy fuel loads were created by multiple southern pine beetle (Dendroctonus frontalis Ehrh.) outbreaks throughout the southern Piedmont between 1999 and 2002. Prescribed burning and mechanical mastication are proposed to reduce fuel loading in beetle-killed pine (Pinus L. spp.) stands in the upper South Carolina Piedmont, but their ecological impacts are unknown. Prescribed burning reduced fuelbed continuity by consuming litter (Oi) and fine (1- and 10-hr timelag size classes) woody fuels immediately after the treatment. Duff (Oe + Oa) layer thickness also decreased and mineral soil was exposed in some areas. Mastication resulted in a thick, continuous layer of shredded …
