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 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.

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

This book was released on 2012-10-22 with total page 88 pages. Available in PDF, EPUB and Kindle. Book excerpt: Prescribed burning is a tool for reducing fuels and restoring a disturbance process to landscapes that historically experienced fire. It is often assumed, or at least desired, that the effects of prescribed burns mimic those of natural fires. However, because of operational and liability constraints, a significant proportion of prescribed burning is, in many ecosystems, conducted at different times of the year than when the majority of the landscape burned historically. This has brought into question the extent to which prescribed fire mimics effects of the historical fire-disturbance regime, and whether there are any negative impacts of such out-of-season burning. Prescribed burning may be conducted at times of the year when fires were infrequent historically, leading to concerns about potential adverse effects on vegetation and wildlife. Historical and prescribed fire regimes for different regions in the continental United States 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, for many ecological variables, 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, presumably because it is not overwhelmed by fire-intensity differences. Most species in ecosystems that evolved with fire appear to be resilient to one or few out-of-season prescribed burn(s). However, a variable fire regime including prescribed burns at different times of the year may alleviate the potential for undesired changes and maximize biodiversity.

This book was released on 2012-12-05 with total page 474 pages. Available in PDF, EPUB and Kindle. Book excerpt: While restoration ecology has traditionally aimed to re-create some putative more ‘natural’ ecological state, forest landscape restoration (FLR) has emerged over the last decade as an approach aimed more at restoring natural functions, while focusing on meeting human needs. With a view to exploring the practical potential of this approach, this book draws together a team of experts from the natural and social sciences to discuss its success so far in addressing critical issues such as biodiversity, ecological function, and human livelihoods. Applying principles of landscape ecology, restoration ecology, planning theory and conflict management, the book presents a series of case studies which document the approach, and discusses how the approach can help with priority setting for the future. The book will provide a valuable reference to graduate students and researchers interested in ecological restoration, forest ecology and management, as well as to professionals in environmental restoration, natural resource management, conservation, and environmental policy.

Available in PDF, EPUB and Kindle. Book excerpt: Between roughly 25 and 31 degrees north latitude, a combination of flat topography, poor soils, and limited surface water produce deserts nearly everywhere on earth. In Florida, however, these conditions support a lavish biota, more diverse than that of any other state east of the Mississippi. In this first comprehensive guide to the state's natural resources in sixty years, thirty top scholars describe the character, relationships, and importance of Florida's ecosystems, the organisms that inhabit them, the forces that maintain them, and the agents that threaten them. From pine flatwoods to coral reef, Ecosystems of Florida provides a detailed, comprehensive, authoritative account of the peninsular state's complex, fragile environments.

Book excerpt: This book is open access under a CC BY-NC 2.5 license. This book provides an unprecedented synthesis of the current status of scientific and management knowledge regarding global rangelands and the major challenges that confront them. It has been organized around three major themes. The first summarizes the conceptual advances that have occurred in the rangeland profession. The second addresses the implications of these conceptual advances to management and policy. The third assesses several major challenges confronting global rangelands in the 21st century. This book will compliment applied range management textbooks by describing the conceptual foundation on which the rangeland profession is based. It has been written to be accessible to a broad audience, including ecosystem managers, educators, students and policy makers. The content is founded on the collective experience, knowledge and commitment of 80 authors who have worked in rangelands throughout the world. Their collective contributions indicate that a more comprehensive framework is necessary to address the complex challenges confronting global rangelands. Rangelands represent adaptive social-ecological systems, in which societal values, organizations and capacities are of equal importance to, and interact with, those of ecological processes. A more comprehensive framework for rangeland systems may enable management agencies, and educational, research and policy making organizations to more effectively assess complex problems and develop appropriate solutions.
