Fire Ecology and Management of the Major Ecosystems of Southern Utah


Book Description

This document provides managers with a literature synthesis of the historical conditions, current conditions, fire regime condition classes (FRCC), and recommended treatments for the major ecosystems in southern Utah. Sections are by ecosystems and include: 1) coniferous forests (ponderosa pine, mixed conifer, and Engelmann spruce-subalpine fir), 2) aspen, 3) pinyon-juniper, 4) big and black sagebrush, and 5) desert shrubs (creosotebush, blackbrush, and interior chaparral). Southern Utah is at the ecological crossroads for much of the western United States. It contains steep environmental gradients and a broad range of fuels and fire regimes associated with vegetation types representative of the Rocky Mountains, the Great Basin, Northern Arizona and New Mexico, and the Mohave Desert. The Southern Utah Demonstration Area consists of contiguous state and federal lands within the administrative boundaries of the Bureau of Land Management (BLM), Fishlake and Dixie National Forests, National Park Sevice, and State of Utah, roughly encompassing the southern 15 percent of Utah (3.24 million ha). The vegetation types described are similar in species composition, stand structure, and ecologic function, including fire regime to vegetation types found on hundreds of millions of hectares in the 11 western states.




Ecosystem Management in the Boreal Forest


Book Description

Forest Ecosystem Management. A management approach that aims to maintain healthy and resilient forest ecosystems by focusing on a reduction of differences between natural and managed landscapes to ensure long-term maintenance of ecosystem functions and thereby retain the social and economic benefits they provide to society.That is the definition of forest ecosystem management proposed in this book, which provides a summary of key ecological concepts supporting this approach. The book includes a review of major disturbance regimes that shape the natural dynamics of the boreal forest and gives examples from different Canadian boreal regions. Several projects implementing the forest ecosystem management approach are presented to illustrate the challenges created by current forestry practices and the solutions that this new approach can provide. In short, knowledge and understanding of forest dynamics can serve as a guide for forest management. Planning interventions based on natural dynamics can facilitate reconciliation between forest harvesting needs and the interests of other forest users.




Towards Sustainable Management of the Boreal Forest


Book Description

Presenting a summary of the development in boreal forest management, this book provides a progressive vision for some of the world's northern forests. It includes a selection of chapters based on the research conducted by the Sustainable Forest Management Network across Canada. It includes a number of case histories.




Poplars and Willows


Book Description

Poplars and willows form an important component of forestry and agricultural systems, providing a wide range of wood and non-wood products. This book synthesizes research on poplars and willows, providing a practical worldwide overview and guide to their basic characteristics, cultivation and use, issues, problems and trends. Prominence is given to environmental benefits and the importance of poplar and willow cultivation in meeting the needs of people and communities, sustainable livelihoods, land use and development.




Boreal Forests and Global Change


Book Description

Boreal forests form Earth's largest terrestrial biome. They are rich in ecosystem and landscape diversity, though characterized by relatively few plant species, as compared to other forested regions. The long term viability and sustainability of boreal forests is influenced by many factors. They are subject to interruptions at intervals by large-scale natural disturbances, and increasingly by human activities. Boreal ecosystem development is typically a slow process; hence rapid changes in the global environment may invoke complex responses. Many industrial nations border, or lie within, boreal regions, deriving much of their economic wealth and culture from the forests. The response of boreal forests to changes in the global environment - whether caused by direct human activity or by indirect changes such as the anticipated changes in climate - are therefore of considerable international interest, both for their policy implications and their scientific challenges. This book which contains almost 50 peer-reviewed papers from a world-wide group of experts assembled under the auspices of IBFRA, the International Boreal Forest Research Association, covers topics which will stimulate further research and the development of constructive policies for improved management and conservation of global boreal forest resources.




Glacier: A Natural History Guide


Book Description

Author and naturalist David Rockwell explains the evolution of the park's geology from the erosion of Australian mountains more than a billion years ago to the glaciers that gave Glacier National Park its distinctive landscape. He explores the natural history of the plants and animals of the park's six distinct regions. You'll learn about the park's greatest predators, grizzly bears, mountain lions, and wolves, and about their complex relationship with their prey. The result is a fascinating and intimate portrait of one of the world's last truly wild places.




Black Cottonwood and Balsam Poplar Managers Handbook for British Columbia


Book Description

Information on black cottonwood and balsam poplar, useful to foresters and woodland managers. Other broadleaf species, such as aspen, red alder or paper birch, are referred to where there are implications for management of cottonwood and poplar. Ecological values are also discussed.
