Large Wind Disturbance in the Boundary Waters Canoe Area Wilderness

Category : Boundary Waters Canoe Area (Minn.)
Languages : en
Pages : 64
Book Description
The Boundary Waters Canoe Area Wilderness (BWCAW) was struck by a major windstorm on July 4, 1999. Estimated volume in blowdown areas was up to 29 percent less than in non-blowdown areas. Mean down woody fuel loadings were twice as high in blowdown areas than in non-blowdown areas. Overstory species diversity declined in blowdown areas, but understory diversity, measured by species richness, increased. Windstorms, like wildfire, are part of the historic disturbance regime in the Boundary Waters-Quetico region.

Book Description
Ecology is the study of the interrelationships between organisms and their environment, including the biotic and abiotic components. There are at least six kinds of ecology: ecosystem, physiological, behavioural, population, and community. Specific topics include: Acid Deposition, Acid Rain Revisited, Biodiversity, Biocomplexity, Carbon Sequestration in Soils, Coral Reefs, Ecosystem Services, Environmental Justice, Fire Ecology, Floods, Global Climate Change, Hypoxia, and Invasion. This new book presents new research on ecology from around the world.
Forest Dynamics and Disturbance Regimes

Book Description
Temperate-zone forests are being shaped continuously by wind, fire and grazing. This book considers these disturbances and consequent issues such as recovery from disturbance, the changing composition of tree species within the forest and the formation of mosaics of different forest types across the landscape.

Category : Boundary Waters Canoe Area (Minn.)
Languages : en
Pages : 320
Book Description
Since its establishment as a federally protected wilderness in 1964, the Boundary Waters has become one of our nation's most valuable--and most frequently visited--natural treasures. When Amy and Dave Freeman learned of toxic mining proposed within the area's watershed, they decided to take action--by spending a year in the wilderness, and sharing their experience through video, photos, and blogs with an audience of hundreds of thousands of concerned citizens. This book tells thedeeper story of their adventure in northern Minnesota: of loons whistling under a moonrise, of ice booming as it forms and cracks, of a moose and her calf swimming across a misty lake. With the magic--and urgent--message that has rallied an international audience to the campaign to save the Boundary Waters, A Year in the Wilderness is a rousing cry of witness activism, and a stunning tribute to this singularly beautiful region.

Natural Disturbances and Historic Range of Variation
Author: Cathryn H. GreenbergPublisher: Springer
ISBN: 3319215272
Category : Nature
Languages : en
Pages : 406
Book Description
This book discusses the historic range of variation (HRV) in the types, frequencies, severities and scales of natural disturbances, and explores how they create heterogeneous structure within upland hardwood forests of the Central Hardwood Region (CHR). The book was written in response to a 2012 forest planning rule which requires that national forests to be managed to sustain ‘ecological integrity’ and within the ‘natural range of variation’ of natural disturbances and vegetation structure. Synthesizing information on HRV of natural disturbance types, and their impacts on forest structure, has been identified as a top need.
