Book Synopsis Seed Dissemination in Small Clearcuttings in North-central California by : Philip M. McDonald
Download or read book Seed Dissemination in Small Clearcuttings in North-central California written by Philip M. McDonald and published by . This book was released on 1980 with total page 796 pages. Available in PDF, EPUB and Kindle. Book excerpt: In a 1964-1967 study on the Challenge Experimental Forest, seedfall was evaluated in 2-, 5-, and 10-acre circular clearcuttings. During the 4 years, 10 seed crops, ranging from light to bumper, were produced by ponderosa pine. white fir, Douglas-fir, and incense cedar. Seedfall ranged from 76 to 40,691 sound seed per acre (188 to 100,547/ha) for a single species in a given year. From 89 to 100 percent of each species' seed fell within an area 1 1/2 times the height of the average dominant tree. Overall, seed distribution was highly variable.

Book Synopsis A Silvicultural Assessment of 10 Lodgepole Pine Stands After Partial Cutting to Reduce Susceptibility to Mountain Pine Beetle by : Roger J. Whitehead
Download or read book A Silvicultural Assessment of 10 Lodgepole Pine Stands After Partial Cutting to Reduce Susceptibility to Mountain Pine Beetle written by Roger J. Whitehead and published by . This book was released on 2007 with total page 56 pages. Available in PDF, EPUB and Kindle. Book excerpt: Over the past 15 years, selective cutting prescriptions have been applied by forest operations in southeastern British Columbia as part of a strategy to reduce landscape-level susceptibility to damage from mountain pine beetle outbreaks. The prescriptions have been applied in stands where maintenance of some mature forest cover is needed to meet management objectives for viewscapes, recreation and habitat or to hold some pine volume during periods of rising beetle activity until it is required or available for harvest. In this study, we examined 10 of these sites 5 to 14 years after harvest, and determined current stand composition and structure from direct sampling and pre- and post-treatment stand characteristics from stand reconstruction. We then related these characteristics to original treatment specifications; the volume removed during harvest and remaining on site after treatment; subsequent losses to wind, snow or bark beetle damage; current stocking status; radial growth rates of residual overstorey trees; and the nature of fuel complexes created and effects of treatment on potential fire behaviour.
Book Synopsis Assessment of the Economic (pulping and Pulp Quality) Effects of Increased Lodgepole Pine in SPF Chip Mixtures by : Barbara Dalpke
Download or read book Assessment of the Economic (pulping and Pulp Quality) Effects of Increased Lodgepole Pine in SPF Chip Mixtures written by Barbara Dalpke and published by . This book was released on 2007 with total page 100 pages. Available in PDF, EPUB and Kindle. Book excerpt: This study is part of a series of research papers that explore the biological, social, and economic aspects of British Columbia's mountain pine beetle epidemic. It examines British Columbia's market kraft and mechanical pulps, which are produced from interior spruce, pine and fir (SPF) and are significant for the province's economy. The chips used to produce SPF pulp are a residual material from lumber operations and are traditionally composed of approximately 30% spruce, 65% lodgepole pine and 5% subalpine fir. However, due to the mountain pine beetle epidemic in the province, this balance is subjected to climb to a pine content of 80% to 90% as salvage harvesting of attacked and dead lodgepole pine stands increases. This study quantitatively and qualitatively defines pulp quality changes with changing chip mixture in order to increase understanding of problems that can be anticipated with changing chip quality needs.--Includes text from Government of Canada publications site and from document.
Book Synopsis Terrestrial Vegetation of California, 3rd Edition by : Michael Barbour
Download or read book Terrestrial Vegetation of California, 3rd Edition written by Michael Barbour and published by Univ of California Press. This book was released on 2007-07-17 with total page 732 pages. Available in PDF, EPUB and Kindle. Book excerpt: "This completely new edition of Terrestrial Vegetation of California clearly documents the extraordinary complexity and richness of the plant communities and of the state and the forces that shape them. This volume is a storehouse of information of value to anyone concerned with meeting the challenge of understanding, managing or conserving these unique plant communities under the growing threats of climate change, biological invasions and development."—Harold Mooney, Professor of Environmental Biology, Stanford University "The plants of California are under threat like never before. Traditional pressures of development and invasive species have been joined by a newly-recognized threat: human-caused climate change. It is essential that we thoroughly understand current plant community dynamics in order to have a hope of conserving them. This book represents an important, well-timed advance in knowledge of the vegetation of this diverse state and is an essential resource for professionals, students, and the general public alike."—Brent Mishler, Director of the University & Jepson Herbaria and Professor of Integrative Biology, University of California, Berkeley
