Available in PDF, EPUB and Kindle. Book excerpt: Representing the work of an interdisciplinary team of 20 specialists, this text consolidates, for the first time, the information available on forest vegetation management and integrates this practice with other silvicultural considerations. It provides a conceptual framework as well as a database for improving forest vegetation management decisions. In an accurate and complete mannner, it quantifies opportunities for enhancing forest productivity, illustrates the value of vegetation management treatments in protecting forest resources and investments, outlines the concept of economic thresholds, highlights progress in establishing such limits and consolidates the information on treatment efficacy, advantages and disadvantages and tradeoffs involved. Forest managers will find it useful to evaluate silvicultural prescriptions and investment decisions; forest planners and resource specialists can use it as a reference source for preparing environmental impact assessments; and regulatory officials can use it to train and upgrade the skills of professionals.

Available in PDF, EPUB and Kindle. Book excerpt: Presents proceedings of a vegetation management conference focusing on alternative methods of vegetation control, ecosystem effects associated with vegetation management practices, and ecosystem management and its implications for forest vegetation management. Topics of presentations include plant competition, the Fallingsnow Ecosystem Project, conifer release treatments, effect of herbicides, forest regeneration, responses of specific tree species to management treatments, understory vegetation responses, hardwood species control, effects of tree spacing, use of biological indicators, effects on small mammals, residual effects of forestry herbicides on plant diversity, herbicide phytotoxicity, decision support systems, microbial control strategies, microclimatic changes following treatments, vegetation dynamics, use of prescribed burning, and the use of sheep in vegetation management. Includes author index.

This book was released on 2012-10-17 with total page 98 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the late 1970s, the outlook for conifer seedlings in new plantations in the Western United States was dismal-too many were dying or growing below the potential of the site. This situation was untenable, and a large study aimed at increasing the survival and growth of planted conifer seedlings was implemented. This was the National Administrative Study on Vegetation Management of which the California portion is reported here. This "study" was really a program on plantation release with 32 individual studies that resulted in more than 60 publications over a 25-year timeframe. The authors emphasized plant community development and biological influences to help explain why some direct release methods were effective and some were not. Survival and growth of several species of conifer seedlings were correlated to the density, foliar cover, and height of various combinations of over 235 species of hardwoods, shrubs, forbs, and graminoids after application of five principal release techniques (herbicides, manual release, mulches, grazing, and mechanical [large machines]). Herbicide use was the most effective treatment followed by manual release and mulches. Domestic grazing, as currently practiced, was not effective, and release with large machines was worthwhile only if followed by an herbicide. Genetic enhancement of conifer seedlings showed promise as a vegetation management tool at first, but lost its efficacy later. Indirect vegetation management by using shade and organic material to reduce the growth and density of competing vegetation has potential, but needs more study. Nineteen principles and 10 conclusions resulted from this research program, but more work in the form of 11 challenges is recommended.

This book was released on 2015-02-14 with total page 96 pages. Available in PDF, EPUB and Kindle. Book excerpt: Inadequate reforestation and poor conifer seedling survival and growth led to a national research and application program on vegetation management in young conifer plantations. Findings from the California part of this program, and more specifically on plantation release, are presented here. Results are from 32 study sites throughout northern and central California and reported in more than 60 publications over a 25-year timeframe. The study sites represent a wide variety of site qualities, soils, slopes, aspects, and vegetation types. Most of the planted conifer seedlings were ponderosa pine (Pinus ponderosa Dougl. ex Laws. var. ponderosa) and Douglas-fir (Pseudotsuga menziesii [Mirb.] Franco var. menziesii).

Available in PDF, EPUB and Kindle. Book excerpt: Public debate has stimulated interest in finding greater compatibility among forest management regimes. The debate has often portrayed management choices as tradeoffs between biophysical and socioeconomic components of ecosystems. Here we focus on specific management strategies and emphasize broad goals such as biodiversity, wood production and habitat conservation while maintaining other values from forestlands desired by the public. We examine the following proposition: Commodity production (timber, nontimber forest products) and the other forest values (biodiversity, fish and wildlife habitat) can be simultaneously produced from the same area in a socially acceptable manner. Based on recent research in the Pacific Northwest, we show there are alternatives for managing forest ecosystems that avoid the divisive arena of 'either-or' choices. Much of the work discussed in this book addresses two aspects of the compatibility issue. First, how are various forest management practices related to an array of associated goods and services? Second, how do different approaches to forest management affect relatively large and complex ecosystems?
