Book Regenerating Coastal Forests in Oregon

Download or read book Regenerating Coastal Forests in Oregon written by and published by . This book was released on 1996 with total page 130 pages. Available in PDF, EPUB and Kindle. Book excerpt: This annotated bibliography was compiled to provide a comprehensive list of sources on the ecological factors that affect forest regeneration. Abstracts from 494 publications are indexed by author, species, and subject, and are arranged into 4 major sections. Topics include the effects of biotic factors, abiotic factors, and stand and site history on vegetation, effects of vegetation on aerial and soil resources, effects of vegetation on stand development, vegetation management, plant succession, and response of vegetation to silvicultural activities and disturbances. The citations are predominately for coastal Douglas-fir occurring west of the Cascade Range in Oregon and Washington; however, applicable citations for associated conifers, hardwoods, shrubs, and herbs and for Alaska, California, and British Columbia are also included. Citations on forest genetics, seeds, seedling physiology, and insects are not included in the bibliography.

Book Twenty Five Years of Managing Vegetation in Conifer Plantations in Northern and Central California Results Application Principles and Challenges

Download or read book Twenty Five Years of Managing Vegetation in Conifer Plantations in Northern and Central California Results Application Principles and Challenges written by Philip McDonald and published by CreateSpace. 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.
