This book was released on 2006 with total page 224 pages. Available in PDF, EPUB and Kindle. Book excerpt: Anthropogenic land use alterations such as livestock grazing and fire suppression have greatly altered sagebrush grasslands of the Great Basin, facilitating invasion of exotic annuals, increases in woody species, and losses of native species. Much of the current research surrounding wildland and prescribed fire in sagebrush dominated ecosystems has focused on a persistent belief that fire in sagebrush systems results in a loss of native flora and a trend toward dominance by exotic annuals. Fire was historically the dominant disturbance throughout the sagebrush steppe and the plant species that comprised these communities possess a variety of adaptations facilitating survival to the fire regime. In order to restore ecosystems, land managers will need to reintroduce natural ecosystem processes, including natural disturbance processes. To describe the response of these plant communities to fire, I examined the plant community response, seedbank response, and reproductive and density responses of three native bunchgrasses (Pseudoroegneria spicata, Achnatherum therberianum, and Elymus elymoides) as well as one native forb (Calochortus macrocarpus) following spring and fall prescribed fires at Lava Beds National Monument. Fires were applied to three Artemisia tridentata ssp. vaseyana (Mountain Big Sagebrush) plant communities with different land use and fire histories. These communities were different in composition ranging from a dominance of exotic annuals to dominance by native grasses, shrubs, and trees. Little is known about how prescribed fire affects the soil seed bank in sagebrush-dominated ecosystems. To address this, we quantified the emergence of Bromus tectorum (cheatgrass) seedlings as well as emergence of seedlings of functional groups (native forbs, bunchgrasses, and shrubs) in a seedbank germination study. At the invasive dominated site (Gillems Camp), we found 91% fewer B. tectorum seedlings germinated in spring burned sites than in controls immediately following spring prescribed burns. However, soils collected one-year following fire had 40% more B. tectorum germinants (8017 germinants/m [superscript 2]) than unburned controls (5132 germinants/m [superscript 2]). Following fall burns at this site there was a similar response, with a 56% immediate reduction in B. tectorum (as compared to unburned control) and a 59% increase in B. tectorum and 58% increase in exotic forb germinants one year following fires. There was an increase in native forb germination following spring burns (94%) and fall burns (45%) at a site dominated by native plants (Fleener Chimneys). Native bunchgrass seed germination declined following spring fire in sites dominated by sagebrush and native understory vegetation (79%), and in sites where Juniperus occidentalis (western juniper) and other woody species dominated (Merrill Caves) (71%). In invasive-dominated sites (Gillems Camp), there was a decrease in B. tectorum cover following both spring (81% decrease) and fall fires (82% decrease), and little native vegetation composition change. Shrub cover, made up predominantly of Chrysothamnus nauseosus, decreased following spring (95% decrease) and fall (93% decrease) fires. At the sagebrush, native understory site (Fleener Chimneys), there was a reduction in native bunchgrass cover (64% decrease), and an increase in native forbs (168% increase) following spring burns, with no changes following fall fires. At the juniper- woody dominated site (Merrill Caves), fire treatments resulted in a decrease in woody plant cover, with no immediate postfire differences seen in the herbaceous plant community. Density of bunchgrass species (Pseudoroegneria spicata, Achnatherum therberianum, Elymus elymoides) did not change following either spring or fall prescribed fire treatments. Fire enhanced flowering was not seen in C. macrocarpus following spring or fall burns at the native or juniper dominated sites. There was increased reproductive effort in native bunchgrass species following fires in all communities studied. Following spring fires at invasive dominated sites, there was a 245% increase in reproductive culms of P. spicata. Following fall fires in native dominated sites, we saw a 974% increase in reproductive culms of P. spicata and a 184% increase in reproductive culms of A. therberianum. Following fall fires at juniper-dominated sites, we saw in an increase in reproductive culms of P. spicata (678% increase), A. thurberianum (356% increase), and Elymus elymoides (209% increase). These results suggest that implementing prescribed fire in order to restore the natural disturbance regime in these fire-adapted ecosystems is beneficial to restoration and preservation of the native biota.

Book excerpt: Prescribed fire is a common land management tool in the southeastern United States. Historical fires occurred primarily in the growing season, but modern day prescribed fire is commonly restricted to the dormant season. Plant community responses to various fire regimes are relatively unknown, and managers require information on how fire regimes impact plant communities. To address these limitations, I studied the impacts of March and June fire on plant communities. Results indicated various woody midstory species respond differently to fire season and community response is driven by species composition. In another study, I examined impacts of February, May-June, and September-October backing and heading fires on midstory and understory vegetation. Results indicated May-June fires maximized midstory mortality and growing-season fires maximized herbaceous understory coverage while dormant-season fire promoted resprouting woody species. Managers can use this information to tailor fire prescriptions to specific properties to better meet management objectives.
Download or read book Fire Country written by Victor Steffensen and published by Hardie Grant Publishing. This book was released on 2020-02-18 with total page 260 pages. Available in PDF, EPUB and Kindle. Book excerpt: Delving deep into the Australian landscape and the environmental challenges we face, Fire Country is a powerful account from Indigenous land management expert Victor Steffensen on how the revival of cultural burning practices, and improved 'reading' of country, could help to restore our land. From a young age, Victor has had a passion for traditional cultural and ecological knowledge. This was further developed after meeting two Elders, who were to become his mentors and teach him the importance of cultural burning. Developed over many generations, this knowledge shows clearly that Australia actually needs fire. Moreover, fire is an important part of a holistic approach to the environment, and when burning is done in a carefully considered manner, this ensures proper land care and healing. Victor's story is unassuming and honest, while demonstrating the incredibly sophisticated and complex cultural knowledge that has been passed down to him, which he wants to share with others. As global warming sees more parts of our planet burning, this book emphasises the value of Indigenous knowledge systems. There is much evidence that, if adopted, it could greatly benefit the land here in Australia and around the world.
Download or read book The Ecological Importance of Mixed Severity Fires written by Dominick A. DellaSala and published by Elsevier. This book was released on 2015-06-08 with total page 450 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Ecological Importance of High-Severity Fires, presents information on the current paradigm shift in the way people think about wildfire and ecosystems. While much of the current forest management in fire-adapted ecosystems, especially forests, is focused on fire prevention and suppression, little has been reported on the ecological role of fire, and nothing has been presented on the importance of high-severity fire with regards to the maintenance of native biodiversity and fire-dependent ecosystems and species. This text fills that void, providing a comprehensive reference for documenting and synthesizing fire's ecological role. Offers the first reference written on mixed- and high-severity fires and their relevance for biodiversity Contains a broad synthesis of the ecology of mixed- and high-severity fires covering such topics as vegetation, birds, mammals, insects, aquatics, and management actions Explores the conservation vs. public controversy issues around megafires in a rapidly warming world
Download or read book Firestick Ecology Fairdinkum Science in Plain English written by Vic Jurskis and published by Connor Court Publishing Pty Limited. This book was released on 2015-08-01 with total page 370 pages. Available in PDF, EPUB and Kindle. Book excerpt: Aborigines came to Australia and burnt out most of the trees and bushes. The megafauna starved whilst eucalypts, herbs, grasses and mesofauna flourished. The ancient culture survived an ice age, global warming and hugely rising seas, forging economies in woodlands and deserts. Europeans doused the firestick, woodlands turned to scrub, mesofauna perished, megafires and tree-eaters irrupted. Foresters rekindled the firestick and greens stole it. Megafires and declines are back with a vengeance whilst ecologists dream-up reasons not to burn. Ecological history shows that we must apply the firestick frequently, willingly and skillfully to restore a healthy, safe environment and economy.

Available in PDF, EPUB and Kindle. Book excerpt: Climate Change: The Facts 2017 contains 22 essays by internationally-renowned experts and commentators, including Dr Bjorn Lomborg, Dr Matt Ridley, Professor Peter Ridd, Dr Willie Soon, Dr Ian Plimer, Dr Roy Spencer, and literary giant Clive James. The volume is edited by Dr Jennifer Marohasy, Senior Fellow at the Institute of Public Affairs. Fourteen of the contributors currently hold or have held positions at a university or a scientific research organisation. Dr Jennifer Marohasy said, "Climate Change: The Facts 2017 presents the case for climate change policies to be based on scientific evidence and it reveals how many of the potential policy responses to climate change are often wildly disproportionate compared to their potential cost." "However, our understanding of how the climate operates is incomplete and it is critically important to challenge the view that the planet is facing a global warming catastrophe." "Climate Change: The Facts 2017 addresses a range of issues including the science of climate change, the homogenisation and manipulation of temperature data, the economic and social impact of climate change policy proposals, and the way climate change is presented by the media and portrayed in popular culture," said Dr Marohasy.
Download or read book Australian Plant Communities written by Raymond Louis Specht and published by Oxford University Press, USA. This book was released on 1999 with total page 510 pages. Available in PDF, EPUB and Kindle. Book excerpt: For 100 million years the Gondwanan vegetation of Australia has survived and developed in the face of vast changes in climate and soils. The pressure imposed on the vegetation by European settlers during the last 200 years is in clear contrast to the minimal impact of Aborigines. Environmental managers and planners predicting the short- and long-term effects of environmental changes on ecosystems need to understand the basic principles of plant community physiology. Australian Plant Communities: The Dynamics of Structure, Growth and Biodiversity is the first synthesis of the physiological processes that shape Australian vegetation at the level of the entire plant community. It examines the basic principles of community physiology by referring to the vegetation of Australia, with its great diversity of natural plant communities, many of which are still relatively undisturbed. The principles developed are applicable to landscapes throughout the world. By revealing the fundamental determinants of vegetation structure, the book enables the effects of climate change on biodiversity, of both vegetation and its associated fauna, to be predicted. Plant Communities in Australia, lavishly illustrated with figures and graphs, is written in a clear and concise style and refers to many studies of the processes operating in Australian vegetation. It is an excellent text for undergraduate and graduate courses in environmental science, resource management, and environmental planning and impact assessment. It is also an invaluable reference for practising environmental scientists, planners, and managers.
