Building capacity and integrating training, education and experience: the Fire Learning Network's Prescribed Burn Training Exchanges
Prescribed fire is an important tool for forest and rangeland management, but there are barriers to its use, including a lack of qualified personnel with the necessary ecological knowledge and operational expertise. In order to implement prescribed fire across landscapes containing a variety of …

Factors Affecting the Regrowth of <i>Ilex glabra</i> in a Routinely Burned Longleaf Forest
… the effects of historical management by use of prescribed fire on <em>Ilex glabra</em> stems/m<sup>2</sup> and factors affecting the regrowth of <em>I. glabra</em> after a prescribed burn to gain beneficial knowledge for management purposes. Environmental factors and morphological parameters of …

EFFECTIVENESS OF PRESCRIBED FIRE ON MEETING FUEL LOAD AND WILDLIFE HABITAT MANAGEMENT OBJECTIVES IN EAST TEXAS NATIONAL FORESTS
… the efficacy of current Forest Service prescribed burn regimes were analyzed for 24 study sites in East Texas National Forests. Study sites were located within Sam Houston, Davy Crockett, and Angelina/Sabine National Forests. Efficacy was determined by comparing defined management …

Occurrence and Characteristics of Nonfruiting Myxobacteria Isolated from Pine Forest Soils
… from pine forest soil Three years after a prescribed burn, the population of nonfruiting myxobacteria was decreased in the burn site. The organisms isolated were distinct from any of the known species of nonfruiting myxobacteria, and apparently are new species.

Within-fire patchiness associated with prescribed burning in the northern Jarrah forests of Western Australia
… on the patchiness (spatial configuration of unburnt and burnt patches which occur at a range of spatial scales) within the perimeter of a single prescribed burn. Of particular concern is the idea that prescribed burning operations, carried out under very restricted weather and environmental …

The Effects of Prescribed Burning on Soil Water Infiltration Rates and Other Select Soil Physical and Chemical Properties in East Texas
<p> This study focused on whether prescribed burning affects soil physical and chemical properties, especially water infiltration, in Western Gulf Coast forests. Soil water infiltration rates were measured 1) pre-burn (before the fire), 2) post-burn (one month after the fire), and 3) at vegetation …

Economics of Managing Loblolly Pine Plantations for Increased Wildlife Biodiversity
… densities, thinning frequency and intensities, prescribed burn intervals, and site indices. Economic analyses used to evaluate management regimes over a range of nonindustrial private landowner (NIPF) alternative rates of return (ARRs) and site indexes were net present worth, land expectation …

Foliar Herbivory on Understory Oaks as a Function of Forest Type and Prescribed Burning
… leaf area to insect herbivores in recently burned or unburned Ozark forest and savanna habitat. In addition, I qualitatively related leaf loss to plant water status, leaf nitrogen (N) concentrations, light, and general environmental conditions. The study took place within the Drury …

Effects of prescribed burning, mechanical and chemical treatments to curtail rhododendron dominance and reduce wildfire fuel loads
… Due primarily to moisture conditions, a single prescribed burn was relatively ineffective in reducing fuel loading and causing R. maximum mortality. Mechanical cutting caused a drastic shift in the size-class distribution of R. maximum but resulted in heavy sprouting and increased fuel loading. …

Spatial distribution of charcoal after a prescribed fire on Middle Mountain, VA
… 2010, The Nature Conservancy conducted a ~150ha prescribed burn in pine- and oak-dominated forests on the eastern slope of Middle Mountain in western Virginia. Data were from three randomly located transects totaling 2751m from the base of the slope extending to the highest elevations. At 50m …

Effects of Prescribed Burning on Black-Capped Vireo Habitat, Territory Establishment, and Production
Prescribed burning has been used since 1979 on the Kerr Wildlife Management Area (Area), Kerr County, Texas, to control regrowth of Ashe juniper (Juniperus ashei). A result of this range management practice has been the redevelopment of a scrub-oak woodland containing vast numbers of live oak …

The Effects of Prescribed Burning by the National Park Service on Pine -Oak Forests Within Great Smoky Mountains National Park
… Mountains National Park (GSMNP) has implemented prescribed burning of pine-oak forests in an attempt to restore and maintain this fire-dependent forest type, which is converting to a mesic broadleaf forest after a long period of fire suppression. One goal of the burning is to create suitable …

A Quantitative Analysis of the Vegetation of Post Oak Savannas in Taney County, Missouri
… or overgrazing. After a first-time prescribed burn of the woodland in the Spring of 1999, individuals smaller than 5 cm DBH suffered 66% mortality, while those over 5 cm DBH suffered only 1.2% mortality. Small, understory trees suffered the highest mortality, while the fire-resistant …

The influence of current year fire on leaf litter decomposition rates and microbial enzyme activity in forests undergoing ecological restoration
… the canopy to remove mesophytic species and prescribed burn regimens to return the plant community to a fire tolerant and dependent one. However it is unclear what effects restoration (or mesophication) has on the decomposition of leaf litter, nutrient cycling, and microbial activity. This …

Evaluating dNBR and CBI for Fire Severity Estimation in Fennoscandian Boreal Surface Fires
… remains challenging due to relatively small burn areas and canopy cover obscuring surface-level fire impacts. This thesis aims to investigate the accuracy of the differenced Normalized Burn Ratio (dNBR), a widely used satellite-derived spectral index, and the Composite Burn Index (CBI), a …

Performance of northern red oak (Quercus rubra) underplantings under five management regimes and across existing environmental gradients
… regimes included 1) control sites, 2) a single prescribed burn, 3) repeat prescribed burns 5) diameter-limit cuts and 4) the seedcut of a shelterwood harvest. Physiographic provinces included the Ridge and Valley and Appalachian Plateau. The direct relationships between seedling performance and …

The autecology of Widdringtonia Cedarbergensis in relation to its conservation management
… Intervals of 15 to 20 years between prescribed burns are recommended on the grounds that cedar stands will be afforded sufficient time to recover from the mortality of the previous fire, especially with respect to seed production. At the same time, this interval should be short enough …
