Prescribed burning for vegetation management on the Blue Ridge Parkway
… practices. This study was designed to compare prescribed burning in the fall or the spring with hand cutting to reduce the overall height of vegetation. Ten scenic overlooks on the Blue Ridge Parkway were selected for treatment. The experiment is a randomized incomplete block design. Four …

Hydrologic Response to Prescribed Burning in the Flint Hills, Kansas
… study aimed at investigating the impacts of prescribed burning on crucial parameters of the hydrologic cycle in the Flint Hills region of Kansas. The study introduces the VELAS model, which employs a daily soil water balance component, providing a more comprehensive simulation of moisture …

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 …

Within-fire patchiness associated with prescribed burning in the northern Jarrah forests of Western Australia
… 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 conditions, can lead to structural and floristic homogenization of the area within a burn perimeter. …

Vegetation Responses to Prescribed Burning in a Mixed-conifer Woodland, Cuyamaca Rancho State Park, California
… study reports the results of light intensity prescribed burning on the vegetation of 3 jeffrey pine-black oak woodland sites in Cuyamaca Rancho State Park, California. The 1.2 ha, 85 ha, and 6 ha burn plots were measured for tree and shrub density and basal area 6 months, 1% years, and 2 years …

Management Tools for Prescribed Burning for Tallgrass Prairie Restoration at the Lewisville Lake Environmental Learning Area
… primary prairie grasses respond favorably to burning. Fuel loads and fuel models vary by scale and survey method. One- and 10-hour fuel moisture can be predicted using a statistical model; 100- and 1,000-hour fuel moisture cannot. Historic weather data suggests that burning can occur when it …

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. …

Comparative determination of tick burden and diversity in intensively managed wildlife estates under those with and without prescribed burning.
Prescribed burning in ex-situ conservancies ecosystems significantly reduces tick burden and diversity. In Zambia, the role of ticks in zoonotic disease transmission is not well described, partly, due to limited available information on tick burden and diversity in ex-situ conservancies. This study …

The Effects of Prescribed Burning on Nutrient Content of Selected Understory Species in an East Texas Loblolly-Shortleaf Pine Stand
… of this study were to determine whether prescribed burning affected nutrient levels in leaves and twigs of six species and whether there were differences in response between leaves and twigs. Backfire and headfire treatments were used to determine differences between burning techniques. …

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 …

Monitoring changes in plant community composition and landscape structure as a result of prescribed burning at Big Oaks National Wildlife Refuge
A vegetation monitoring program was initiated at Big Oaks National Wildlife Refuge (Big Oaks NWR) to help understand the effects of fire management on critical wildlife habitat. The objectives of this study were to produce a baseline description of plant community structure and composition and to …

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 …

The Effect of Prescribed Burning on Soil Microbial Communities, Nutrients, and Carbon Dioxide Fluxes Under and Between Sagebrush Canopies in the Semi-Arid Rangelands of Northern Nevada
… severity, and management practices pre-and-post burning. The cultivation of squirreltail (Elymus elymoides (Raf. Swezey), a desirable perennial plant species, can be used to curb the spread of cheatgrass. A prescribed burn was conducted at the University of Nevada Reno Experimental Station Gund …

Effects of prescribed fire timing on vigor of sericea lespedeza in the Kansas Flint Hills
We evaluated effects of annual, prescribed burning on vigor of the noxious weed, sericea lespedeza (Lespedeza cuneata; SL) in native tallgrass prairie over a 4-yr period. We hypothesized that annual prescribed burning conducted during the growing season would selectively pressure SL, whereas …

Managing disturbance in the longleaf pine ecosystem: effects of managed fire regime characteristics on fire hazard and community ecology at multiple spatial scales
… biological diversity. To compensate, aggressive prescribed fire programs are necessary. The fragmented nature of this ecosystem combined with the difficulty, complexity, and expense of applying regular prescribed fire in a densely populated landscape raises numerous management challenges. The …

Herptile Abundance and Diversity in Response to Seasonal Burning on a Central Texas Ashe Juniper-Live Oak Savanna
… the seasonal effects (summer versus winter) of prescribed burning on the herpetofaunal community of a central Texas Ashe juniper-live oak savanna. One trapping line, consisting of 1 drift fence, 2 pitfall traps and 2 funnel traps, was established on 12 treatment (6 on each burn treatment) and 6 …
