DOWNLOAD EBOOKHPO42-, H2PO4-, FeHPO4 (aq), MgHPO4 (aq), CaHPO4 (aq), MnHPO4 (aq), FeH2PO4+, CaH2PO4+, and CaPO4- were major compounds of P in the soil solution in the Pine Rockland. Prescribed fire significantly increased extractable concentrations of these P compounds after14 days, except for FeH2PO4+. Within a relatively low P availability, solubility of P in the soil solution was controlled by vivianite and MnHPO4, and undersaturated with Ca/Mg-P minerals. Changes of ionic activities in the soil solution following the fire shifted equilibrium of P between vivianite and MnHPO4.

DOWNLOAD EBOOKHistorical and prescribed fire regimes for different regions in the continental U.S. were compared and literature on season of prescribed burning synthesized. In regions and vegetation types where considerable differences in fuel consumption exist among burning seasons, the effects of prescribed fire season appears to be driven more by fire-intensity differences among seasons than by phenology or growth stage of organisms at the time of fire. Where fuel consumption differs little among burning seasons, the effect of phenology or growth stage of organisms is often more apparent, because it is not overwhelmed by fire-intensity differences. Species in ecosystems that evolved with fire appear to be resilient to one or few out-of-season prescribed burns. Illus.

DOWNLOAD EBOOKA biodiversity hotspot, Florida is home to many ecosystems and species that evolved in the presence of frequent fire. In this book, Reed Noss discusses the essential role of fire in generating biodiversity and offers best practices for using fire to keep the region's ecosystems healthy and resilient. Reviewing several lines of evidence, Noss shows that fire has been important to the southeastern Coastal Plain for tens of millions of years. He explains how the region's natural fire regimes are connected to its climate, high rate of lightning strikes, physical chemistry, and vegetation. But urbanization and active fire suppression have reduced the frequency and extent of fires. Noss suggests the practice of controlled burning can and should be improved to protect fire-dependent species and natural communities from decline and extinction. Noss argues that fire managers should attempt to simulate natural fire regimes when conducting controlled burns. Based on what the species of the Southeast likely experienced during their evolutionary histories, he makes recommendations about pyrodiversity, how often and in what seasons to burn, the optimal heterogeneity of burns, mechanical treatments such as cutting and roller-chopping, and the proper use of fuel breaks. In doing so, Noss is the first to apply the new discipline of evolutionary fire ecology to a specific region. This book is a fascinating history of fire ecology in Florida, an enlightening look at why fire matters to the region, and a necessary resource for conservationists and fire managers in the state and elsewhere.

DOWNLOAD EBOOKPine rocklands are fire-prone ecosystems with limited spatial extent, and have experienced reduced area in the previous decades through habitat conversion and urbanization. The purpose of this dissertation research was to evaluate the historical range of variability of fire activity and spatial patterns of fires in a pine rockland ecosystem in the National Key Deer Refuge (NKDR) on Big Pine Key in the Lower Florida Keys. To investigate the temporal and spatial patterns in fire activity, I (1) evaluated the temporal patterns for fires in my study area in the NKDR, (2) analyzed differences in standard fire history metrics since the advent of land management in the 1950s, (3) mapped the spatial extents of fires that scarred > 25% of the recording trees, (4) investigated how regression relationships fire activity and microtopographic parameters changed with aggregated scale, and (5) calculated global and local indications of spatial autocorrelation in the geographic fire-scar data. The 2011 fire was no more severe than other historic fires in the dataset, and was within a range of expectations for severe fires in the area. The relationships between fire activity and microtopography peaked at approximately 50 m (residual topography p

DOWNLOAD EBOOKWildland fires are an integral component of the ecosystems of tropical pine rocklands and subtropical pine flatwoods. Fuels such as leaf litter and understory vegetation accumulated rapidly and in less than a decade can reach dangerous levels that can drastically increase fire intensity in both prescribed fires and wildfires. Land use changes in the regions occupied by these forests have resulted in the exclusion of fire from many areas that formerly burned frequently. Land development has resulted in a mix of land uses, some of which make fire management difficult. These changes have created challenges for both prescribed fire application and the mitigation of wildfire risks.
