Book Description
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.

Third International Conference on Forest Vegetation Management
Author: Dean Gordon Thompson
Publisher:
ISBN:
Category : Nature
Languages : en
Pages : 546
Book Description
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.

Vegetation Management for Reforestation
Twenty-Five Years of Managing Vegetation in Conifer Plantations in Northern and Central California: Results, Application, Principles, and Challenges

Pages : 98
Book Description
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.
