FIRE BEHAVIOR ACROSS A VEGETATION GRADIENT AND PEAT COMBUSTION VULNERABILITY IN SOUTH FLORIDA

Unknown Date (has links)
Fire is a tool to reduce fuel and restore ecosystems but poses a risk of peat combustion that temporally restricts managers. Studies indicate that fires may be prescribed with a water table lower than the peat surface, but are based on locations with different peat properties or assumed heat inputs. The goal of this research is to quantify peat surface heating during a passing fire and the heat required to ignite peat under lowered water tables. This study used temperature probes at two heights to quantify peat surface heating during a prescribed fire and a manipulative experiment to quantify the effects of water table recession on peat properties important for predicting ignition. The soil surface experienced 87% of the flaming heat in sawgrass dominated areas. The heat required to ignite the peat surface was significantly correlated with the water table depth. This provides managers greater opportunity for prescribing fire. / Includes bibliography. / Thesis (M.S.)--Florida Atlantic University, 2021. / FAU Electronic Theses and Dissertations Collection

Impacts of Prescribed Fire and Grazing on Northern Great Plains Rangelands

Johnson, Haley Mae Ann January 2018 (has links)
Prescribed burning was utilized as a management tool on grasslands of the Northern Great Plains. We analyzed the use of fire to manipulate encroaching and unpalatable western snowberry (Symphoricarpos occidentalis), to promote browsing and improve nutritive quality. Fire was successful at altering the nutrient quality of western snowberry and selectivity of grazing livestock from plant specific to patch specific. Additionally, we evaluated the difference between burn season and frequency on plant community dynamics of an ungrazed tallgrass prairie invaded by Kentucky bluegrass (Poa pratensis). Fire promoted native forb and grass species, stressing that native species are well adapted to the historical disturbance. Our research emphasizes the need for restored fire regimes in the Northern Great Plains to benefit numerous aspects of prairie ecosystem function, stability, services, and productivity. / U.S. Forest Service / Central Grasslands Research and Extension Center

Pilot Validation of VSMOKE with Implications for Smoke Management Regulations

Bernier, Robert Michael 06 June 2011 (has links)
Prescribed burning (Rx) has become increasingly subjected to various regulations. Among these regulations are ordinances that restrict downwind impacts of smoke from prescribed fires. Regulations can severely limit burn managers and private landowners from using Rx as a forest management tool. This research can help us move away from these simplistic regulations, and help promote a regulatory environment in which scientific tools and knowledge are used to prohibit only activities for which the evidence suggests there will be adverse consequences. This research was divided into three parts that consisted of: (1) a pilot validation of the smoke emission model VSMOKE-GIS; (2) review of southeastern states' smoke management guidelines (SMG); and (3) a geographic analysis of Virginian's current SMG. VSMOKE-GIS showed good accuracy in predicting the PM2.5 concentration and location of the smoke plume downwind. Criteria were identified when managing Rx smoke and the strengths, weaknesses, and implications were discussed of the Rx programs. The geographic analysis demonstrated quantitatively how much area may be impacted with minimal apparent benefit. This research should provide a clearer spatial picture of the smoke management barriers associated with Rx on private woodlands in Virginia. These results should be a useful tool in developing a regulatory environment that encourages Rx when the conditions are optimal. We conclude with future recommendations for Virginia. / Master of Science
