Download or read book Ecology and Recovery of Eastern Old Growth Forests written by Andrew M. Barton and published by Island Press. This book was released on 2018-11-08 with total page 362 pages. Available in PDF, EPUB and Kindle. Book excerpt: The landscapes of North America, including eastern forests, have been shaped by humans for millennia, through fire, agriculture, hunting, and other means. But the arrival of Europeans on America’s eastern shores several centuries ago ushered in the rapid conversion of forests and woodlands to other land uses. By the twentieth century, it appeared that old-growth forests in the eastern United States were gone, replaced by cities, farms, transportation networks, and second-growth forests. Since that time, however, numerous remnants of eastern old growth have been discovered, meticulously mapped, and studied. Many of these ancient stands retain surprisingly robust complexity and vigor, and forest ecologists are eager to develop strategies for their restoration and for nurturing additional stands of old growth that will foster biological diversity, reduce impacts of climate change, and serve as benchmarks for how natural systems operate. Forest ecologists William Keeton and Andrew Barton bring together a volume that breaks new ground in our understanding of ecological systems and their importance for forest resilience in an age of rapid environmental change. This edited volume covers a broad geographic canvas, from eastern Canada and the Upper Great Lakes states to the deep South. It looks at a wide diversity of ecosystems, including spruce-fir, northern deciduous, southern Appalachian deciduous, southern swamp hardwoods, and longleaf pine. Chapters authored by leading old-growth experts examine topics of contemporary forest ecology including forest structure and dynamics, below-ground soil processes, biological diversity, differences between historical and modern forests, carbon and climate change mitigation, management of old growth, and more. This thoughtful treatise broadly communicates important new discoveries to scientists, land managers, and students and breathes fresh life into the hope for sensible, effective management of old-growth stands in eastern forests.
Download or read book Diversity and Dynamics in Forest Ecosystems written by Munesh Kumar and published by Apple Academic Press. This book was released on 2021-11 with total page 382 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Providing a wealth of in-depth knowledge of forest ecosystems, this new volume explores a collection of important topics on forest community dynamics. It looks at the diversity of forest ecosystems and explores such aspects as forest products in enhancing local livelihoods and community participation, forage production, forest conservation and sustainable management, regeneration patterns, seed handling, and more. Chapters in Diversity and Dynamics in Forest Ecosystems present new research on forest products, livelihood generation mechanisms of forest-dependent communities, utilization patterns of untapped resources from forests, and the structure of different ecosystems from the tropical to the temperate landscape. This book also features different drivers of community dynamics, such as the role of seed handling in forests, the influence of altitudinal variations, and protected and community-conserved forests on the forest diversity. Chapters also consider the role of nontimber forest products and their significance in livelihood diversification for tribal communities and forage crop genetic resources, and forest resource extraction by forest fringe dwellers. Also explored are aspects of soil organic carbon in agroforestry systems and integrated approaches of sustainable agroforestry development in diverse forest ecosystems. This edition also examines the vegetation structure and regeneration aspects of timberline zone, including diversity of herbaceous flora along the altitudinal gradient. The abundance of in-depth knowledge of the diversity and dynamics of forest ecosystems in this volume will be valuable in conservation and management of forests, which play an important role in the world environment. Forests are presently facing multiple disturbances, and this volume will help forestry professionals and others formulate further strategies to mitigate global climate change and other challenges"--
Download or read book Long Term Forest Dynamics of the Temperate Zone written by Paul A. Delcourt and published by Springer. This book was released on 1987-08-13 with total page 464 pages. Available in PDF, EPUB and Kindle. Book excerpt: The synthesis presented in this volume is a direct outgrowth of our ten-year FORMAP Project (Forest Mapping Across Eastern North America from 20,000 yr B.P. to the Present). Many previous research efforts in paleoecology have used plant-fossil evidence as proxy information for primarily geologic or climatic reconstructions or as a bio stratigraphic basis for correlation of regional events. In contrast, in this book, we deal with ecological questions that require a holistic perspective that integrates the interactions of biota with their dynamically changing environments over time scales up to tens of thousands of years. In the FORMAP Project, our major research objective has been to use late-Quaternary plant-ecological data sets to evaluate long-term patterns and processes in forest de velopment. In order to accomplish this objective, we have prepared subcontinent-scale calibrations that quantitatively relate the production and dispersal of arboreal pollen to dominance in the vegetation for the major tree types of eastern North America. Quantification of pollen-vegetation relationships provides a basis for developing quan titative plant-ecological data sets that allow further ecological analysis of both individual taxa and forest communities through time. Application of these calibrations to fossil pollen records for interpreting forest history thus represents a fundamental step beyond traditional summaries based upon pollen percentages.

Available in PDF, EPUB and Kindle. Book excerpt: This handbook in two volumes synthesises our knowledge about the ecology of Central Europe’s plant cover with its 7000-yr history of human impact, covering Germany, Poland, the Netherlands, Belgium, Luxembourg, Switzerland, Austria, Czech Republic and Slovakia. Based on a thorough literature review with 5500 cited references and nearly 1000 figures and tables, the two books review in 26 chapters all major natural and man-made vegetation types with their climatic and edaphic influences, the structure and dynamics of their communities, the ecophysiology of important plant species, and key aspects of ecosystem functioning. Volume I deals with the forests and scrub vegetation and analyses the ecology of Central Europe’s tree flora, whilst Volume II is dedicated to the non-forest vegetation covering mires, grasslands, heaths, alpine habitats and urban vegetation. The consequences of over-use, pollution and recent climate change over the last century are explored and conservation issues addressed.

Available in PDF, EPUB and Kindle. Book excerpt: The objective of this study was to provide managers with national-level data on current conditions of vegetation and fuels developed from ecologically based methods to address these questions: How do current vegetation and fuels differ from those that existed historically? Where on the landscape do vegetation and fuels differ from historical levels? In particular, where are high fuel accumulations? When considered at a coarse scale, which areas estimated to have high fuel accumulations represent the highest priorities for treatment?

Traditional pressures of development and invasive species have been joined by a newly-recognized threat: human-caused climate change. It is essential that we thoroughly understand current plant community dynamics in order to have a hope of conserving them. This book represents an important, well-timed advance in knowledge of the vegetation of this diverse state and is an essential resource for professionals, students, and the general public alike."—Brent Mishler, Director of the University & Jepson Herbaria and Professor of Integrative Biology, University of California, Berkeley
Download or read book Costa Rican Ecosystems written by Maarten Kappelle and published by University of Chicago Press. This book was released on 2016-04-15 with total page 798 pages. Available in PDF, EPUB and Kindle. Book excerpt: In 1502, Christopher Columbus named Costa Rica, and while gold and silver never materialized to justify the moniker of rich coast in purely economic terms, scientists and ecotravelers alike have long appreciated its incredible wealth. Wealth in Costa Rica is best measured by its biodiversityhome to a dizzying number of plants and animals, many endemic, it s a country that has long encouraged and welcomed researchers from the world over, and is exemplary in the creation and commitment to indigenous conservation and management programs. Costa Rica is considered to have the best preserved natural resources in Latin America. Approximately nine percent (about 1,000,000 acres) of Costa Rica has been protected in 15 national parks, and a comparable amount of land is protected as wildlife refuges, forest reserves or Indian reservations. This long-awaited synthesis of Costa Rican ecosystems is an authoritative presentation of the paleoecology, biogeography, structure, conservation, and sustainable use of Costa Rica s ecosystems. It systematically covers the entire range of Costa Rica s natural and managed, terrestrial, freshwater and marine ecosystems, including its island systems (Cocos Islands), the Atlantic and Pacific oceans and shores (coasts, coral reefs, mangrove forests), its lowlands (dry, season and wet forests), its highlands (the northern volcanoes and southern Talamanca s), and its estuaries, rivers, lakes, swamps and bogs. The volume s integrated, comprehensive format will be welcomed by tropical and temperate biologists alike, by biogeographers, plant and animal ecologists, marine biologists, conservation biologists, foresters, policy-makers and all scientists, natural history specialists and all with an interest in Costa Rica s ecosystems."
Download or read book The Forest Inventory and Analysis Database written by Sharon W. Woudenberg and published by Createspace Independent Pub. This book was released on 2012-10-19 with total page 344 pages. Available in PDF, EPUB and Kindle. Book excerpt: This publication is based on previous documentation of the nationally standardized Forest Inventory and Analysis database (Hansen and others 1992; Woudenberg and Farrenkopf 1995; Miles and others 2001). Documentation of the structure of the Forest Inventory and Analysis database (FIADB) for Phase 2 data, as well as codes and definitions, is provided. Examples for producing population level estimates are also presented. This database provides a consistent framework for storing forest inventory data across all ownerships for the entire United States. Forest Inventory and Analysis (FIA) is a continuing endeavor mandated by Congress in the Forest and Rangeland Renewable Resources Planning Act of 1974 and the McSweeney-McNary Forest Research Act of 1928. FIA's primary objective is to determine the extent, condition, volume, growth, and depletion of timber on the Nation's forest land. Before 1999, all inventories were conducted on a periodic basis. The passage of the 1998 Farm Bill requires FIA to collect data annually on plots within each State. This kind of up-to-date information is essential to frame realistic forest policies and programs. USDA Forest Service regional research stations are responsible for conducting these inventories and publishing summary reports for individual States. In addition to published reports, the Forest Service provides data collected in each inventory to those interested in further analysis. This report describes a standard format in which data can be obtained. This standard format, referred to as the Forest Inventory and Analysis Database (FIADB) structure, was developed to provide users with as much data as possible in a consistent manner among States. A number of inventories conducted prior to the implementation of the annual inventory are available in the FIADB. However, various data attributes may be empty or the items may have been collected or computed differently. Annual inventories use a common plot design and common data collection procedures nationwide, resulting in greater consistency among FIA work units than earlier inventories. Data field definitions note inconsistencies caused by different sampling designs and processing methods.
Download or read book Ecology and Conservation of Forest Birds written by Grzegorz Mikusiński and published by Cambridge University Press. This book was released on 2018-03-29 with total page 568 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ecology and Conservation of Forest Birds is a unique review of current understanding of the relationships between forest birds and their changing environments. Large ecological changes are being driven by forest management, climate change, introduced pests and pathogens, abiotic disturbances, and overbrowsing. Many forest bird species have suffered population declines, with the situation being particularly severe for birds dependent on attributes such as dead wood, old trees and structurally complex forests. With a focus on the non-tropical parts of the Northern Hemisphere, the text addresses the fundamental evolutionary and ecological aspects of forest birds using original data analyses and synthesising reviews. The characteristics of bird assemblages and their habitats in different European forest types are explored, together with the macroecological patterns of bird diversity and conservation issues. The book provides a valuable reference for ecologists, ornithologists, conservation professionals, forest industry employees, and those interested in birds and nature.
Download or read book Fire and Climatic Change in Temperate Ecosystems of the Western Americas written by Thomas T. Veblen and published by Springer Science & Business Media. This book was released on 2006-05-10 with total page 456 pages. Available in PDF, EPUB and Kindle. Book excerpt: Both fire and climatic variability have monumental impacts on the dynamics of temperate ecosystems. These impacts can sometimes be extreme or devastating as seen in recent El Nino/La Nina cycles and in uncontrolled fire occurrences. This volume brings together research conducted in western North and South America, areas of a great deal of collaborative work on the influence of people and climate change on fire regimes. In order to give perspective to patterns of change over time, it emphasizes the integration of paleoecological studies with studies of modern ecosystems. Data from a range of spatial scales, from individual plants to communities and ecosystems to landscape and regional levels, are included. Contributions come from fire ecology, paleoecology, biogeography, paleoclimatology, landscape and ecosystem ecology, ecological modeling, forest management, plant community ecology and plant morphology. The book gives a synthetic overview of methods, data and simulation models for evaluating fire regime processes in forests, shrublands and woodlands and assembles case studies of fire, climate and land use histories. The unique approach of this book gives researchers the benefits of a north-south comparison as well as the integration of paleoecological histories, current ecosystem dynamics and modeling of future changes.
