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.

Book Twenty Five Years of Managing Vegetation in Confier Plantations in Northern and Central California

Download or read book Twenty Five Years of Managing Vegetation in Confier Plantations in Northern and Central California written by McDonald and published by CreateSpace. 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).

Book Growth and Allocation of Woody Biomass in Forest Trees Based on Environmental Conditions

Download or read book Growth and Allocation of Woody Biomass in Forest Trees Based on Environmental Conditions written by Luigi Todaro and published by MDPI. This book was released on 2021-04-23 with total page 214 pages. Available in PDF, EPUB and Kindle. Book excerpt: Forest ecosystems are important because of the key role in reducing atmospheric greenhouse gas concentrations by storing a large amount of carbon in biomass and soils. The relative amount of above-ground biomass allocated among different tree tissues is a functional indicator of forests’ health reflecting the material flow, the wood quality and the plant survival strategy. The way in which plants steer their photosynthetic product across their compartments is not fixed but likely vary over time, across growth economies and among species and, lastly, is influenced by plant size and climate, Obtaining a qualitative/quantitative understanding of the influence that these factors have in both growth and biomass allocation is of fundamental importance either in understanding plant ecology and evolution and into developing environmental policies and useful forest management practices to cope with future climate change.

Book Ecological Silvicultural Systems

Download or read book Ecological Silvicultural Systems written by Brian J. Palik and published by John Wiley & Sons. This book was released on 2024-01-23 with total page 342 pages. Available in PDF, EPUB and Kindle. Book excerpt: ECOLOGICAL SILVICULTURAL SYSTEMS Unleash the natural power and adaptability of forests with this cutting-edge guide For generations, silvicultural systems have focused largely on models whose primary objective is the production of timber, leading to drastically simplified forests with reduced ecological richness, diversity, and complexity. Ecological silviculture, by contrast, focuses on producing and maintaining forests with “all their parts”—, that is, with the diversity and flexibility to respond and adapt to global changes. Ecological silviculture seeks to emulate natural development models and sustain healthy forests serving multiple values and goals. Ecological Silvicultural Systems provides a comprehensive introduction to these approaches and their benefits tailored to diverse types of forests, designed for forest management professionals. It provides a series of exemplary models for ecological silviculture and surveys the resulting forest ecosystems. The result is a text that meets the needs of professionals in forestry and natural resource management with an eye towards sustaining healthy forest ecosystems, adapting them to climate change, protecting them from invasive species, and responding to changing market forces. Ecological Silvicultural Systems readers will also find: Detailed treatment of forest ecosystems in North America, Europe, South America, and Australia A broad field of contributors with decades of combined expertise on multiple continents Discussion of pine woodlands; temperate hardwood forests, boreal forests, temperate rainforests, and more Ecological Silvicultural Systems is a useful reference for professional foresters, wildlife habitat managers, restoration ecologists, and undergraduate and graduate students in any of these fields.

Book Proceedings National Silvicultural Workshop

Download or read book Proceedings National Silvicultural Workshop written by and published by . This book was released on 2001 with total page 96 pages. Available in PDF, EPUB and Kindle. Book excerpt: Silviculture, as an integrative discipline, must combine management skills with scientific and technical knowledge in the management of forests and woodlands. While traditionally, silviculturists worked in fine resolution landscapes, today's practitioner must look at encompassing both larger geographic areas (adjacent stands, watersheds, regions, subregions) and wider objectives (trees as well as wildlife, commodities, recreation, sustainability, biological diversity, air quality, and ecosystem resilience). The 12 papers in this proceedings explore the past, present, and desired future of silviculture's role and practice. Examination of disturbance ecology in ecosystem management includes natural and induced disturbances, and management options. Discussion of desired future conditions includes the importance of understanding the connection between ecological values and social values, as well as historic reference conditions as they relate to creating forest plans. A section on inventory, monitoring, and adaptive management looks at multiresource and multiscale data assessments and temporal continuity; included are design alternatives and a discussion of how to adapt silvicultural prescriptions. Case studies throughout the proceedings help the reader understand the practical applications, the successes, and the need for further work.
