Download or read book Invasive Species in Forests and Rangelands of the United States written by Therese M. Poland and published by Springer Nature. This book was released on 2021-02-01 with total page 455 pages. Available in PDF, EPUB and Kindle. Book excerpt: This open access book describes the serious threat of invasive species to native ecosystems. Invasive species have caused and will continue to cause enormous ecological and economic damage with ever increasing world trade. This multi-disciplinary book, written by over 100 national experts, presents the latest research on a wide range of natural science and social science fields that explore the ecology, impacts, and practical tools for management of invasive species. It covers species of all taxonomic groups from insects and pathogens, to plants, vertebrates, and aquatic organisms that impact a diversity of habitats in forests, rangelands and grasslands of the United States. It is well-illustrated, provides summaries of the most important invasive species and issues impacting all regions of the country, and includes a comprehensive primary reference list for each topic. This scientific synthesis provides the cultural, economic, scientific and social context for addressing environmental challenges posed by invasive species and will be a valuable resource for scholars, policy makers, natural resource managers and practitioners.
Download or read book Rule based Mapping of Fire adapted Vegetation and Fire Regimes for the Monongahela National Forest written by Melissa A. Thomas-Van Gundy and published by . This book was released on 2007 with total page 28 pages. Available in PDF, EPUB and Kindle. Book excerpt: S2The use of prescribed fire is expected to increase as efforts to restore fire-dependent ecosystems gain momentum nationally. The documentation of historical fire regimes is essential for setting restoration objectives that include prescribed burning. To aid the Monongahela National Forest in this endeavor, a rule-based approach was employed in GIS to map fire-adapted vegetation and fire regimes. Spatial analyses and maps were generated using ArcMap 9.1 using the proclamation boundary of the Monongahela National Forest as our study area. Based on current knowledge of fire-vegetation-site relationships, we reviewed available data sets for relevancy in estimating fire regimes. Four themes were selected: land type association, potential natural vegetation (primary and secondary), and current forest type. All themes were converted to 20 m2 grids. Selected features of each theme were scaled from 1 through 5 according to their relationship to fire, with 1 representing conditions most conducive to fire and 5 the least. Each theme was weighted to reflect its inferred effect on system fire adaptation. The resulting fire adaptation scores were then categorized into standard fire regime groups. Fire regime group V (200+ yrs fire frequency) was the most common, assigned to more than 510,000 ha, primarily in the Allegheny Mountains Section. Fire regime group I (low & mixed severity, 0- 35 yrs) and III (low & mixed severity, 35 -200 yrs) were assigned to nearly 198,000 ha, primarily in the Ridge and Valley Section and one subsection within the Allegheny Mountains Section. The resultant maps are intended to identify fire-adapted systems for land management purposes. These systems likely will require active silviculture using fire and/or fire surrogates for their maintenance or restoration. The transparent rule-based procedure can be easily modified and, as such, possesses the flexibility for application to other ecosystems with similar spatial databases. S3.

Download or read book Southern Forest Science written by and published by . This book was released on 2004 with total page 402 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Southern forests provide innumerable benefits. Forest scientists, managers, owners, and users have in common the desire to improve the condition of these forests and the ecosystems they support. A first step is to understand the contributions science has made and continues to make to the care and management of forests. This book represents a celebration of past accomplishments, summarizes the current state of knowledge, and creates a vision for the future of southern forestry research and management. Chapters are organized into seven sections: "Looking Back," "Productivity," "Forest Health," "Water and Soils," "Socioeconomic," "Biodiversity," and "Climate Change." Each section is preceded by a brief introductory chapter. Authors were encouraged to focus on the most important aspects of their topics; citations are included to guide readers to further information."
Download or read book Responses of Forest Ecosystems to Nitrogen Deposition written by Frank S Gilliam and published by Mdpi AG. This book was released on 2021-10-29 with total page 172 pages. Available in PDF, EPUB and Kindle. Book excerpt: Despite effective global-scale legislation to restrict the emissions of nitrogen (N) into the atmosphere, atmospheric deposition of N remains high in many forested regions. In addition, many N-impacted forests still retain the imprint of N saturation, such as altered species composition and leaching of essential base cations. Accordingly, we need a further understanding of the complexities of N cycling in forest ecosystems and the effects of excess N on forest biodiversity and biogeochemical cycling. This volume explores these complexities, including effects on plants, plant assemblages, and forest biogeochemistry, by synthesizing research from Asia, Europe, and North America. Because of the widespread nature of current declines in N deposition, this book ends with a look to the future as N-impacted forests experience a return to lower levels of atmospheric deposition of N.
Download or read book Peterson Field Guide To Moths Of Northeastern North America written by David Beadle and published by HarperCollins. This book was released on 2012-04-17 with total page 635 pages. Available in PDF, EPUB and Kindle. Book excerpt: There are thousands of moth species in the northeast of North America, and while it might seem that they are all drab grays and browns, there is actually a startling variety. They come in a rainbow of colors, from brilliant oranges and pinks to soft greens and violets. There are moths with colorful leopard-like spots, and ones that look more like B-movie aliens; some that are as large as your hand, and others the size of a grain of rice. With helpful tips on how to attract and identify moths, range maps and season graphs showing when and where to find each species, and clear photographs that use the unique Peterson arrow system for easy identification, this guide provides everything an amateur or experienced moth-watcher needs. Sponsored by the National Wildlife Federation and the Roger Tory Peterson Institute.
Download or read book The Fernow Watershed Acidification Study written by Mary Beth Adams and published by BoD – Books on Demand. This book was released on 2006-04-28 with total page 298 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Fernow Watershed Acidification Study is a long-term, paired watershed acidification study. This book describes the responses to chronic N and S amendments by deciduous hardwood forests, one of the few studies to focus on hardwood forest ecosystems. Intensive monitoring of soil solution and stream chemistry, along with measurements of soil chemistry, and vegetation growth and chemistry, provide insights into the acidification process in forested watersheds.
