This book was released on 2015 with total page 26 pages. Available in PDF, EPUB and Kindle. Book excerpt: Each year, the U.S. Forest Service prescribes burns within the George Washington and Jefferson National Forest(GWJNF). Burns are prescribed in the growing (late April-October) and dormant season (November- mid-April). The goal of the burns is to reinstate the natural fire regime, returning forests to their original species composition. Currently in GWJNF, Appalachian pine-oak forests are experiencing an increase in fire-intolerant species, while Quercus species and Gaylussacia brachycera, an endangered shrub species, are declining. In the summer of 2014, a vegetation survey was conducted on Buck Mountain, West Virginia to determine if there was a significant difference between dormant and growing season burns compared to a no-burn control. A total of 60 plots (15 per treatment) was established within a site burned once (in the dormant season), a site burned twice (dormant burn followed by a growing season burn), a site burned twice (both dormant), and a site protected from fire (control). We hypothesized that burns would have differing effects on woody vegetation, depending on fire treatment and shade tolerance. We predicted that Quercus species and G. brachycera would increase after a growing season burn. We found that Quercus ilicifolia regeneration, as well as G. brachycera were more abundant at burn sites, regardless of season. Our results suggest that seasonality of burns did not affect oak and G. brachycera regeneration at Buck Mountain. Future vegetation monitoring is needed to determine if time intervals between burns affects regeneration of desired species rather than the season of burn.
Download or read book Seed Bank Response to Prescribed Fire in the Central Appalachians written by and published by . This book was released on 2010 with total page 16 pages. Available in PDF, EPUB and Kindle. Book excerpt: Pre- and post-treatment seed-bank characteristics of woody species were compared after two prescribed fires in a mesic mixed-oak forest in the central Appalachians. Nineteen woody species were identified from soil samples. Mean species richness declined but evenness did not after prescribed burning. The seed bank was dominated by black birch, yellow-poplar, blackberry, grapevine and Hercules club before burning. Following burning, the median density of seed bank propagules declined by 45 percent. Black birch, yellow-poplar, and grapevine declined by 69, 56, and 40 percent, respectively. The results illustrate the importance of the seed bank as a robust source of non-oak regeneration in mixed-oak forests and of the potential effect of fire altering it.

Cunningham and published by . This book was released on 1978 with total page 106 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ctenosciaena gracilicirrhus é uma espécie de peixe marinho demersal, da família Sciaenidae. Os exemplares estudados foram coletados pelo N/Oc. "Prof. W. Besnard", durante quatro cruzeiros oceanográficos, realizados durante o ano de 1975, sobre a plataforma continental brasileira entre as latitudes de 22°10'S e 30°S, uma em cada estação do ano. Em decorrência da elevada abundância numérica da espécie na ictiofauna de fundo da costa centro-sul do Brasil, estudaram-se a bionomia e biologia, sendo que no total foram capturados 11.995 exemplares, utilizando-se rede de arrasto de fundo. Entre 22°27'S e 29°35'S não havia sido assinalada a ocorrência de C. gracilicirrhus. A amplitude de variação de comprimento total dos indivíduos oscilou entre 30 e 200 mm, sendo que as modas que se destacaram foram as das classes de 80 e 150 mm, para o período global. O recrutamento ocorreu no inverno-primavera-verão com um máximo na primavera. O processo da primeira maturação sexual inciou-se quando as fêmeas apresentavam um comprimento médio total de 113,5 mm e os machos de 107,0 mm, estando no primeiro ano de vida. E o processo de maturação sexual se completava quando as fêmeas alcançavam 165,0 mm de comprimento médio total e os machos com 170,0 mm.

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.

Download or read book Third Year Effects of Shelterwood Cutting Wildlife Thinning and Prescribed Burning on Oak Regeneration Understory Vegetation Development and Acorn Production in Tennessee written by and published by . This book was released on 2005 with total page 61 pages. Available in PDF, EPUB and Kindle. Book excerpt: In 2000, a study was implemented at Chuck Swan State Forest and Wildlife Management Area to compare the effectiveness of prescribed burning, shelterwood cutting, wildlife thinning, and wildlife thinning with prescribed fire for improving wildlife habitat and enhancing oak regeneration. Treatments were implemented in four similar mixed hardwood stands with a northwest aspect. In 2003, a follow-up study was conducted to: 1) document third-year effects of prescribed fire alone, wildlife thinning, wildlife thinning with prescribed fire, and shelterwood cutting on the density and size of oak regeneration and woody competitors, 2) quantify effects of prescribed fire alone, wildlife thinning, wildlife thinning with prescribed fire, and shelterwood cutting on understory composition and the development of understory structure, 3) investigate effects of deer browsing on plant response from prescribed fire alone, wildlife thinning, wildlife thinning with prescribed fire, and shelterwood cutting, and 4) document white oak acorn production within the control and shelterwood cutting and wildlife thinning treatments. In 2003, the response of yellow poplar, sassafras, black cherry, blackgum, and sumac to the treatments was stronger than the response of oak, as evidenced by significant increases in the abundance of these competitors over oak, and no significant differences between treatments in the abundance of red and white oaks. Treatments did not significantly affect composition of herbaceous species, and this was likely due to the low overall abundance of herbaceous cover and high variability in the composition of herbaceous species within and between the replicate stands. Understory structure up to 101 cm (39.8 in) was significantly increased by the shelterwood, wildlife thinning, and wildlife thinning with prescribed fire treatments. However, this structure was mainly comprised of woody species. Effects of deer browsing on understory vegetation were not detected. Species richness and percent herbaceous cover did not differ between fenced and unfenced treatments. Mean values for white oak acorn production and crown size were highest in the wildlife thinning treatments. Differences in the means were not significant in 2003, but it appears that a trend is emerging. Future monitoring of deer browsing effects and white oak acorn production is warranted, and future work involving additional applications of prescribed fire and mechanical and chemical treatment of undesirable components of the woody understory would be useful with respect to oak regeneration and development of herbaceous species.

Download or read book Wildland Fuel Fundamentals and Applications written by Robert E. Keane and published by Springer. This book was released on 2014-11-04 with total page 195 pages. Available in PDF, EPUB and Kindle. Book excerpt: A new era in wildland fuel sciences is now evolving in such a way that fire scientists and managers need a comprehensive understanding of fuels ecology and science to fully understand fire effects and behavior on diverse ecosystem and landscape characteristics. This is a reference book on wildland fuel science; a book that describes fuels and their application in land management. There has never been a comprehensive book on wildland fuels; most wildland fuel information was put into wildland fire science and management books as separate chapters and sections. This book is the first to highlight wildland fuels and treat them as a natural resource rather than a fire behavior input. Moreover, there has never been a comprehensive description of fuels and their ecology, measurement, and description under one reference; most wildland fuel information is scattered across diverse and unrelated venues from combustion science to fire ecology to carbon dynamics. The literature and data for wildland fuel science has never been synthesized into one reference; most studies were done for diverse and unique objectives. This book is the first to link the disparate fields of ecology, wildland fire, and carbon to describe fuel science. This just deals with the science and ecology of wildland fuels, not fuels management. However, since expensive fuel treatments are being planned in fire dominated landscapes across the world to minimize fire damage to people, property and ecosystems, it is incredibly important that people understand wildland fuels to develop more effective fuel management activities.

Download or read book Ecology and Control of Introduced Plants written by Judith H. Myers and published by Cambridge University Press. This book was released on 2003-05-15 with total page 332 pages. Available in PDF, EPUB and Kindle. Book excerpt: The global spread of plant species by humans is both a fascinating large scale experiment and, in many cases, a major perturbation to native plant communities. Many of the most destructive weeds today have been intentionally introduced to new environments where they have had unexpected and detrimental impacts. This 2003 book considers the problem of invasive introduced plants from historical, ecological and sociological perspectives. We consider such questions as 'What makes a community invasible?', 'What makes a plant an invader?' and 'Can we restore plant communities after invasion?' Written with advanced students and land managers in mind, this book contains practical explanations, case studies and an introduction to basic techniques for evaluating the impacts of invasive plants. An underlying theme is that experimental and quantitative evaluation of potential problems is necessary, and solutions must consider the evolutionary and ecological constraints acting on species interactions in newly invaded communities.
