This book was released on 2018-03-29 with total page 32 pages. Available in PDF, EPUB and Kindle. Book excerpt: Prescribed burning is an important tool throughout Southern forests, grasslands, and croplands. The need to control fire became evident to allow forests to regenerate. This manual is intended to help resource managers to plan and execute prescribed burns in Southern forests and grasslands. A new appreciation and interest has developed in recent years for using prescribed fire in grasslands, especially hardwood forests, and on steep mountain slopes. Proper planning and execution of prescribed fires are necessary to reduce detrimental effects, such as the impacts on air and downstream water quality.

This book was released on 2015 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Terrestrial ecosystems in the southeastern United States have evolved with fire as a common disturbance and as a result many natural communities require the presence of fire to persist over time. Human development precludes natural fires from occurring within these communities; however, prescribed fire is considered to be a critical tool in the effort to restore fire-dependent ecosystems after decades of fire exclusion. Direct effects of fire on individual floral and faunal species as well as benefits to biodiversity at the landscape (gamma diversity) level have largely been supported in previous research. However, information on the effects of natural and prescribed fire on plant diversity at the local level (alpha diversity) is limited, particularly for southeastern forests. The applicability of the Intermediate Disturbance Hypothesis (IDH), which suggests that the highest levels of biodiversity are found at intermediate levels of disturbance, is also untested for North Florida upland plant communities. This study compared the effects of fire on local scale mean plant species diversity by examining burned and unburned portions of three fire-dependent communities to determine if there is an effect of prescribed fire on in alpha biodiversity. Alpha biodiversity was not significantly different (p=0.433) between burned and unburned fire-dependent plant communities in northern Florida, suggesting that prescribed fire does not affect plant species diversity in these communities and/or the IDH for plant communities is not supported at the time scale tested. However, the application of prescribed fire did result in changes in abundance of species, particularly with species such as Dicanthelium acuminatum, Quercus myrtifolia, and Vaccinium myrsinites, that respond positively to fire, which may have implications for associated faunal diversity.

This book was released on 2006 with total page 36 pages. Available in PDF, EPUB and Kindle. Book excerpt: Agriculture, fire suppression, and urbanization have drastically altered natural forest processes and conditions since humankind settled in the Southeastern United States. Today, many of South Carolina's forests are dense and overstocked, with high fuel loads. These conditions increase the susceptibility of forests to southern pine beetle attack and wildfire. These threats are further complicated by rapid urbanization and forest fragmentation, processes that are increasing South Carolina's wildland-urban interface at a rapid rate. Prescribed fire is an effective, economical, and widely used tool for reducing fuel loads and encouraging desired vegetative communities in forest landscapes. However, research into the effects of prescribed fire often generates more questions than answers. This paper considers fire effects on soil erosion, nutrients, and vegetation from a historical perspective. We examined historical fire regimes, land use changes, and fire research. The majority of literature indicates that soil erosion does not occur unless a severe climatic event follows prescribed fire. There is also evidence of a fertilization effect in the soil following prescribed fire, although this is typically of short duration and accompanied by some nutrient loss in the forest floor. Effects of prescribed fire on the productivity, composition, and regeneration of vegetation are more complex and ambiguous. Effects are primarily determined by antecedent local conditions and fire severity and intensity. Knowledge of past land use and fire's biological and historical roles in land use change can support effective decision making. This knowledge will provide guidance for sustainable management of forest resources and reduction of hazardous forest fuel conditions.

This book was released on 2008 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Fire is an important factor affecting plant diversity and vegetation dynamics in subtropical grasslands in southern Brazil. Although fire is a useful management tool in many ecosystems, in Brazil its use is forbidden and very polemic. Therefore, the aim of this thesis is to evaluate the effects of fire on plant strategies and vegetation dynamics. The study was carried out in southern Brazil (Rio Grande do Sul State). Experimental fires and mowing were performed and vegetation regeneration was analyzed according to different functional groups and plant strategies. In addition, population biology of chosen species was studied in order to investigate effects of fire on plant populations. Finally, studies about the bud bank were conducted to evaluate vegetation potential to regenerate after fire events. The results of this thesis are of crucial importance for the conservation of subtropical grasslands in southern Brazil.

Book excerpt: The theory of ecological convergence underlies the biogeographers' maps of world biome-types. It also determines the degree to which ecological principles, derived from research on particular populations, communities or ecosystems, are generally valid, and hence also to what extent resource management principles are general. To quote Di Castri and Mooney (1973): "In effect, in order to assess the transfer of technology, it is essential to know to what extent information acquired from studying one particular ecosystem is applicable to another ecosystem of the same type but situated in a different location. " The five relatively small, isolated, mediterranean-climate zones of the earth, each with its distinct fauna and flora, have provided the ideal testing grounds for this theory. A heritage of precisely focused ecosystems research has resulted, beginning with the international comparative analyses conducted by Specht (l969a, b) but with antecedents in earlier studies in South Australia (Specht and Rayson 1957, Specht 1973). Cody and Mooney (1978) reviewed the information available at the time for the four zones excepting Australia and concluded that the arrays of strategy-types to be found among the different biotas were so similar that they could be explained only in terms of the convergence hypothesis; nevertheless, evident differences in community organization and dynamics, especially phenol ogy, required closer study of resource availability and resource-use patterns to better explain relations between form and function overall, and to assess the degree of convergence at higher levels of organization than the population.

This book was released on 2018-05-15 with total page 359 pages. Available in PDF, EPUB and Kindle. Book excerpt: A 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.

Available in PDF, EPUB and Kindle. Book excerpt: Historical 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.

Available in PDF, EPUB and Kindle. Book excerpt: Grasslands can support high levels of biodiversity and provide numerous ecosystem services, but they have been widely degraded, often via loss of natural disturbance regimes. North American grasslands were once created and maintained by fire. In some cases, fire has been more important than climate in determining the distribution and extent of grasslands. Conservation of the biodiversity harbored by grasslands relies, in part, on ecological restoration of these habitats and the fire regimes that historically maintained them. In this dissertation, I examined the effects of prescribed fire on grassland plant species and plant communities of the southern Great Plains in the short-term (up to two years after fire) and longer-term (twelve years after fire). Cool-season prescribed burns (those conducted in January – March) were not sufficient to shift overall plant community composition (e.g., increase richness of native plant species or reduce cover of the invasive grass Bothriochloa ischaemum) in 10 sites distributed from central Texas to southern Oklahoma (Chapter 2). However, these fires did have measurable effects on eight individual forb species in the same sites (Chapter 3). In general, the eight forb species studied individually responded to the winter fire individualistically, but all three annual species increased their floral displays (flowers/m2) in the burned plots in the short term. Forb species that increased their floral display in burned areas did so via increased plant biomass (grams of dry aboveground biomass) or plant density (plants/m2). We found little evidence that these forb species shifted their resource allocation towards reproduction. In a separate study (Chapter 4), a prescribed fire conducted in July was sufficient to shift plant community composition in the short term, mostly by reducing the cover of the invasive grass B. ischaemum and increasing native species richness; the latter effect was likely the result of reducing B. ischaemum. In the same study, only the increases in native grass cover and richness were still detectable twelve years after the fire. Perhaps due to two additional cool-season fires across the entire site, B. ischaemum cover remained low twelve years after the fire in burned plots but unexpectedly had also decreased in unburned plots. The results from all three chapters supported our expectation that summer fires would be more effective than cool-season fires in changing the plant community composition, including controlling the invasive grass B. ischaemum. Interestingly, forb species were highly individualistic, from differences in their abundances among sites in the multi-site study (Chapter 3) to differences in their responses to fire (Chapter 4). These findings support conducting prescribed fires in summer months to control invasive grasses and to increase native plant species richness, and consequently conserve the biodiversity supported by grasslands in this region
