Delayed conifer mortality after fuel reduction treatments: interactive effects of fuel, fire intensity, and bark beetles.
Many low-elevation dry forests of the western United States contain more small trees and fewer large trees, more down woody debris, and less diverse and vigorous understory plant communities compared to conditions under historical fire regimes. These altered structural conditions may contribute to increased probability of unnaturally severe wildfires, susceptibility to uncharacteristic insect o...
متن کاملNenana Ridge Experimental Fuel Treatments
Chronology The A-Unit of the Nenana Ridge burn project (Fig.1) was ignited with a test burn at 13:40 on 6/17/09. Winds were light (2 mph, gusting to 6 mph) out of the southwest with a relative humidity of 47% (using Kestrel), and temperature of 69 deg F taken at the overlook. Blacklining began on W and E sides of the unit. Initially, only white smoke (indicating high fuel moistures) could be se...
متن کاملResiliency of an Interior Ponderosa Pine Forest to Bark Beetle Infestations Following Fuel-Reduction and Forest-Restoration Treatments
Mechanical thinning and the application of prescribed fire are commonly used to restore fire-adapted forest ecosystems in the Western United States. During a 10-year period, we monitored the effects of fuel-reduction and forest-restoration treatments on levels of tree mortality in an interior ponderosa pine, Pinus ponderosa Dougl. ex Laws., forest in California. Twelve experimental plots, rangi...

متن کاملShort-term Effects of Fuel Reduction Treatments on Soil Mycorrhizal Inoculum Potential in Beetle-killed Stands
Heavy fuel loads were created by southern pine beetle (Dendroctonus frontalis Ehrh.) outbreak throughout the southeastern Piedmont during the early 2000s. Prescribed burning and mechanical mulching (mastication) were used to reduce fuel loading, but many ecological impacts are unknown. Successful forest regeneration depends on ectomycorrhizal (ECM) or vesicular-arbuscular mycorrhizal (VAM) fung...
