Comparison of thinning and prescribed fire restoration treatments to Sierran mixed-conifer historic conditions
Thinning and prescribed fire are widely used to restore fire-suppressed forests, yet there are few studies of their effectiveness in Sierran mixed-conifer forest. We compared stand conditions in replicated plots before and after a combination of thinning and burning treatments against a reconstruction of the same forest in 1865. The historical forest had 67 stems/ha (trees ‡5 cm DBH), equal per...
متن کاملEarly impacts of forest restoration treatments on the ectomycorrhizal fungal community and fine root biomass in a mixed conifer forest
1. The obligate symbiosis formed between ectomycorrhizal fungi (EMF) and roots of tree species in the Pinaceae influences nutrient uptake and surrounding soil structure. Understanding how EMF respond to prescribed fire and thinning will assist forest managers in selecting fuel-reducing restoration treatments that maintain critical soil processes and site productivity. 2. The response of EMF spe...
متن کاملForest-floor treatments in Arizona ponderosa pine restoration ecosystems: No short-term effects on plant communities
––Leaf litter accumulation during fire exclusion and increases in tree density in postsettlement southwestern Pinus ponderosa forests may limit the establishment of understory vegetation. We performed an experiment in P. ponderosa forests of northern Arizona to ascertain plant community responses to forest-floor scarification and Oi removal on thirty-six 100-m2 plots overlaid on an existing eco...
متن کاملIntroduction to the Special Issue on Sierran Mixed-Conifer Research
LIKE MUCH OF THE WESTERN UNITED STATES, California’s forest has been severely altered by a century of fire suppression. The Sierra Nevada’s largest forest type, mixed conifer, which is primary habitat for more vertebrate species than any other Californian forest community, historically burned every 12–17 years. In 1894, John Muir wrote “The inviting openness of the Sierra woods is one of their ...
متن کاملSpatial variability in microclimate in a mixed-conifer forest before and after thinning and burning treatments
In the western United States, mechanical thinning and prescribed fire are common forest management practices aimed at reducing potential wildfire severity and restoring historic forest structure, yet their effects on forest microclimate conditions are not well understood. We collected microclimate data between 1998 and 2003 in amixed-conifer forest in California’s Sierra Nevada. Air and soil te...
