Initial changes in forest structure and understory plant communities following fuel reduction activities in a Sierra Nevada mixed conifer forest
The widespread attention that has been devoted to wildfires by the public, as well as by state and federal governments, over the last several years in the United States has created a demand for fuel reduction activities aimed at alleviating wildfire hazard. While the appropriateness of these fuel reduction activities has been discussed in detail in previous studies, only a few studies have expe...
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...
متن کاملSpatial and temporal variability of canopy cover and understory light in a Cerrado of Southern Brazil.
Canopy cover has significant effects on the understory environment, including upon light availability for seedling growth. The aim of the present study was to verify spatial heterogeneity and seasonal changes in the canopy cover of a dense Cerrado area, and their relationship to understory photosynthetic active radiation availability. Leaf area index (LAI) values in the rainy season varied from...
متن کاملCanopy Openness, Understory Light Environments, and Oak Regeneration
Understory light environments were evaluated in four mixed-oak forests in southern Ohio using hemispherical photography. Within each forest, plots were divided into nine treatment combinations based on three pretreatment fire categories and three Integrated Moisture Index (IMI) categories. For each of 108 photographs we determined the percentage of open sky, direct beam, and diffuse radiation; ...
متن کاملSpatial Structure Changes in Mohtasham Urban Area of Kashan
Today, Mohtasham urban area in Kashan does not benefit from a suitable condition and has lost its importance over the last decades. The vast majority of the local inhabitants of this historical area have left their homes and have been replaced by weak and underprivileged dwellers of the urban community.
