Fire effects on small mammals and vegetation of the Northern Chihuahuan Desert
The role of fire in the Northern Chihuahuan Desen has been of great interest and also heavily debated for 40 years. However, few replicated studies have documented the changes brought about by fire. .My study documented the short term effects of fire on a creosotebush (Larrea tridentata) dominated …

The 2006 Warm Fire: effects on habitat and prey species of the northern goshawk
Reductions in the frequency of fire in Southwestern ponderosa pine and mixed-conifer forests since initiation of forest management early in 20th century changed the composition and structure of the forest habitats of the northern goshawks (Accipiter gentilis), a food-limited species of conservation …

Enhanced Nonlinear Truss Model for Capturing Combined Earthquake and Fire Effects in RC Structures
Post-earthquake fires can negatively affect the safety and collapse probability of Reinforced Concrete (RC) structures. At present, there has been no systematic effort to assess the performance of RC structures for combined earthquake and fire effects. Developing appropriate guidelines for this …

Prescribed Fire Effects on Tree Grades and Wounds on the Monongahela National Forest, WV
… to withstand potential heating from wildland fire. Trees exhibiting similarities for these properties and others may be classified into two broad functional groups: pyrophytes and pyrophobes. To our knowledge, few research studies have been conducted to determine how prescribed fires may …

Prescribed Fire Effects on Woodland Structure, Light Levels and Understory Plant Communities in Missouri Oak-Hickory Woodlands
Prescribed fire is a tool used to manage oak-hickory woodlands for wildlife habitat. This study examined how prescribed fire affected woodland structure and how this structure alters transmittance of light within Drury-Mincy Conservation Area, (Taney County, Missouri). Sampling occurred in twenty …

Building a better burn: Fuel characterization and fire effects in silvicultural systems in the southern United States
Landscape-scale fire suppression and poor timber harvesting practices with little regard for post-harvest conditions have contributed to a decline in xerophytic pine (Pinus spp.) and oak (Quercus spp.) forests in the eastern United States and in the Appalachian Mountain region. The success of …

Fire Effects on Soil and Water Quality in the Sierra Nevada Mountains and Great Basin Ecosystems: Emphasis on Nitrogen
The effects of fire on soil and water chemistry have been an area of intense study in recent years. Prescribed fires are increasing as a fire management tool in the Sierra Nevada Mountains in order to remove ladder fuels and mitigate the threat of catastrophic wildfire. The first two studies in …

Vegetation Ecology and Fire Effects on Community Structure, Composition, and Diversity in a Barrens Remnant and a Flatwoods in Southern Illinois
Fire effects on composition and diversity at both sites were greatest in the ground-layer vegetation as there were significant increases in species diversity and cover and dramatic changes among dominant species. Most increase in species diversity appears to be from soil seed banks. At GCB the …

Long-Term Study of Prescribed Fire Effects on Stand Dynamics and Oak Regeneration Potentials in Degraded Upland Oak-Hickory Stands in Northwestern Arkansas
… Absence of regular, frequent disturbances (e.g., fire and harvesting) in these systems for an extended time period prior to the decline, had allowed mesophication (more closed-canopy, increases in more shade-tolerant, fire-sensitive species, and the resulting cool, damp conditions with less …

Soil Microbial Community Dynamics In Florida Scrub Ecosystem
Pyrogenic ecosystems are maintained by fires which vary in frequency, seasonality, and intensity. Florida oak-saw palmetto scrub ecosystem is characterized by fires occurring at intervals of 10-20 years. Diverse factors as private land acquisition and development has created a patchy distribution …

Turning up the heat: fire ecology and climate adaptive silviculture in longleaf pine forests
Frequent fire is required to maintain the characteristic structure, function, and high biodiversity of longleaf pine woodlands. Longleaf pine regeneration is exposed to this frequent fire, yet persists as both patches and single tree regeneration. While research has shown that this regeneration …

Evaluating dNBR and CBI for Fire Severity Estimation in Fennoscandian Boreal Surface Fires
Fire severity—the magnitude of ecological change induced by fire—plays a critical role in shaping post-fire recovery dynamics, carbon cycling, and forest management decisions. In Fennoscandian boreal forests, however, accurate severity estimation using remote sensing remains challenging due to …

An assessment of the representation of fire severity and coarse woody debris dynamics in an ecosystem management model
Fire is the most significant natural disturbance agent in the MSdm biogeoclimatic subzone and has a determinant role in the dynamics of lodgepole pine (Pinus contorta ssp. latifolia Engelm.ex S.Wats.) dominated forests. Fire severity is a controversial term that usually refers to a qualitative …

Fire and non-native grass invasion across a heterogeneous landscape in the Central Hardwoods
… the potential to change natural and prescribed fire regimes by altering fuels, which in turn may promote further invasion. I examined if invasion by Microstegium vimineum, a non-native annual grass resulted in a positive invasion-fire feedback in eastern deciduous forests managed with prescribed …

Assessment of Passive Fire Protection on Steel-Girder Bridges
… US are severely damaged or suffer collapse from fires at significant rates, even when compared to other hazards such as earthquakes. Fire-induced bridge collapses are perpetuated by the general lack of installed fire protection systems. Therefore, new materials and applications are needed to …

Floristic dynamics of Appalachian pine-oak forests over a prescribed fire chronosequence
Vegetation dynamics after prescribed fire were modeled on three mountains in the George Washington National Forest representing a chronosequence of conditions since burning: pre-burn, and 1, 2 and 12 years post-treatment. Vegetation structure was more affected by environmental and spatial (burn …

Impacts of Fire on Bats in the Central Appalachians
Fire occurrence was widespread in the central Appalachians pre-European settlement due to Native American ignition and occasional lightning strikes, and continued through European settlement. During this time, low to mixed severity burns supported a suite of ecological communities that were fire …
