This book was released on 2005 with total page 85 pages. Available in PDF, EPUB and Kindle. Book excerpt: An approach for synthesizing the results of ecological research pertinent to land management is the analysis of the historic range of variability (HRV) for key ecosystem variables that are affected by management activities. This report provides an HRV analysis for the upland vegetation of the Medicine Bow National Forest in southeastern Wyoming. The variables include live tree density, dead tree (snag) density, canopy cover, abundance of coarse woody debris, species diversity, fire return intervals, the abundance of various diseases, the proportion of the landscape in different land cover types, and the degree of patchiness in the landscape. The variables were examined at the stand and landscape scales, using information available in the literature and USFS databases. High-elevation landscapes were considered separately from low-elevation landscapes. Much of the report pertains to forests dominated by lodgepole pine, subalpine fir, and Engelmann spruce at high elevations, and by ponderosa pine and aspen at lower elevations. We defined the HRV reference period for the MBNF as approximately 1600 to 1860.

Book excerpt: The fusion of individualistic community ecology with the Hutchinsonian niche concept enabled a broad integration of ecological theory, spanning all the way from the niche characteristics of individual species, to the composition, structure, and dynamics of ecological communities. Landscape ecology has been variously described as the study of the structure, function, and management of large heterogeneous land areas. Any reading of the published landscape ecology literature shows near uniformity in the adoption of a categorical patch-mosaic paradigm. However, if biological communities are multivariate gradients of species composition, with each species responding individualistically to particular combinations of limiting factors, is a categorical patch-based representation appropriate? We evaluate the sufficiency of several patch-based representations of vegetation at the landscape level to explain the composition of the plant community. Classified vegetation maps all performed poorly in explaining the composition and structure of forest trees among plots. Different categorical vegetation maps provided largely independent explanations of species variability. Individual species models based on spectral, topographic, and climatic variables vastly out-performed those produced using the classified maps. By moving from a landscape ecological paradigm based on categorical patches to one based on quantitative species and environmental responses across continuous space, it will be possible to both produce much more effective predictions of species distributions and ecological processes and remove much of the disjunction between landscape ecology and mainstream community ecology theory.

Available in PDF, EPUB and Kindle. Book excerpt: At the time of European discovery, the ancient North Americanforests stretched across nearly half the continent. And while todaylittle remains of this past glory, efforts are underway to bringback some of the diverse ecosystems of that era. America's AncientForests: From the Ice Age to the Age of Discovery providesscientists and professionals with essential information for forestrestoration and conservation projects, while presenting acompelling and far-reaching account of how the North Americanlandscape has evolved over the past 18,000 years. The book weaves historical accounts and scientific knowledge into adynamic narrative about the ancient forests and the events thatshaped them. Divided into two major parts, it covers first theglaciers and forests of the Ice Age and the influences of nativepeoples, and then provides an in-depth look at these majesticforests through the eyes of the first European explorers. Changesin climate and elevation, the movement of trees northward, theassembly of modern forests, and qualities that all ancient forestsshared are also thoroughly examined. A special feature of this book is its self-contained introductionto the early history of Native American peoples and theirenvironment. The author draws on his roots in the Osage nation aswell as painstaking research through the historical record,offering a complete discussion of how the cultural practices ofhunting, agriculture, and fire helped form the ancient forests.
