This book was released on 1992 with total page 78 pages. Available in PDF, EPUB and Kindle. Book excerpt: Hardwoods have long been disposed of to create coniferous forests of high quality. Recently, there have been concerns that this policy is a mistake, not only because the demand for hardwoods is growing but because of the negative aspects of growing coniferous monocultures. This analysis examined hardwood inventory, ecology, management, and use issues through a summary of hardwood inventory in the Kamloops Forest Region, a field assessment of management practices and stand conditions in two subzones in the region, and a review of literature related to paper birch and black cottonwood, the predominant species in the productive subzones. The field assessment consisted of the sampling of regeneration stands younger than 20 years to identify management practices that were successful for hardwood, conifer, or mixedwood production. Immature-mature stands older than 20 years were sampled across a range of ecosystems to assess their stand structure, species composition, and growth and yield.

Book excerpt: NEW YORK TIMES BEST SELLER • From the world's leading forest ecologist who forever changed how people view trees and their connections to one another and to other living things in the forest—a moving, deeply personal journey of discovery Suzanne Simard is a pioneer on the frontier of plant communication and intelligence; her TED talks have been viewed by more than 10 million people worldwide. In this, her first book, now available in paperback, Simard brings us into her world, the intimate world of the trees, in which she brilliantly illuminates the fascinating and vital truths--that trees are not simply the source of timber or pulp, but are a complicated, interdependent circle of life; that forests are social, cooperative creatures connected through underground networks by which trees communicate their vitality and vulnerabilities with communal lives not that different from our own. Simard writes--in inspiring, illuminating, and accessible ways—how trees, living side by side for hundreds of years, have evolved, how they learn and adapt their behaviors, recognize neighbors, compete and cooperate with one another with sophistication, characteristics ascribed to human intelligence, traits that are the essence of civil societies--and at the center of it all, the Mother Trees: the mysterious, powerful forces that connect and sustain the others that surround them. And Simard writes of her own life, born and raised into a logging world in the rainforests of British Columbia, of her days as a child spent cataloging the trees from the forest and how she came to love and respect them. And as she writes of her scientific quest, she writes of her own journey, making us understand how deeply human scientific inquiry exists beyond data and technology, that it is about understanding who we are and our place in the world.

Download or read book British Columbia s Inland Rainforest written by Susan Stevenson and published by UBC Press. This book was released on 2011-07 with total page 458 pages. Available in PDF, EPUB and Kindle. Book excerpt: The vast temperate rainforests of coastal British Columbia are world renowned, but much less is known about the other rainforest located 500 kilometres inland along the western slopes of the interior mountains. The unique integration of continentality and humidity in this region favours the development of lush rainforest communities that incorporate both coastal and boreal elements. In British Columbia's Inland Rainforest, scientists bring together, for the first time, a broad spectrum of information about this distinctive ecosystem. They also consider the ecological consequences of human activities in the rainforest and present strategies for its management and conservation.
Download or read book The Effect of Paper Birch Betula Papyrifera Marsh Root Reinforcement on Terrain Stability in British Columbia written by Kirstin Anne Campbell and published by . This book was released on 2001 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Management of paper birch in mixedwood stands is a sustainable forest management practice. In addition to the ecological and economical benefits of mixedwoods, paper birch trees can maintain or enhance slope stability. This thesis attempted to quantify the contribution of birch root reinforcement in BC to slope shear resistance. The objectives of this thesis were to determine the: 1) genetic variation in paper birch root reinforcement, 2) environmental variation in root reinforcement between birch and pine, and 3) differences in root reinforcement between birch and pine. The first study compared the contribution of birch and pine roots (from different populations growing in three soil types) to soil shear resistance using two controlled environment shear tests (Sonotube and Polytube Experiments). The second study (Tree Uprooting Experiment) compared the vertical uprooting resistance of birch and pine growing in different soil types at three field study sites. The third study (Genecology Experiment) determined the variation of four birch populations growing at one location. Results from the tube experiments found that the roots of birch and pine trees contributed to a significant increase in shear strength, regardless of soil type. At a depth of 20-44 cm, paper birch increased shear strength by as much 88%, while pine increased strength by as much as 61%. There was little variation in root reinforcement among the six birch populations in the Sonotube Experiment, which suggested that these trees were from one generalist population rather than six specialist populations. Soil texture affected the root reinforcement of birch and pine in the Polytube Experiment~ both species had the highest root reinforcement in coarse textured sand and the least root reinforcement in medium textured silt. The limiting factor in root reinforcement, in this case, was attributed to a lack of water and nutrients in the silt soil. In the Tree Uprooting Experiment, birch trees had 50% greater resistance to uprooting than did pine trees. Small diameter birch and pine at Aleza Lake had greater uprooting resistance than birch and pine at other field sites. However, larger diameter trees at Gregg Creek and Red Rock had greater uprooting resistance than similar size trees at Aleza Lake. Soil strength and moisture content may have accounted for the uprooting resistance differences among diameter classes at Aleza Lake. Results from the Genecology Experiment showed that the Skeena population had the greatest uprooting resistance, and the greatest height, diameter, and root biomass compared to the other three populations. The results from companion trials, and from the uprooting tests suggested that Skeena trees represent a generalist population. In the same experiment, the nursery where the trees were grown impacted uprooting resistance, even after five years growing in the field. The results from this study reconfirmed the significant length of time nursery can affect field performance. Significant findings arising from this thesis were that: 1) birch saplings have greater root strength than pine across all soil types, 2) root system structure has an important role in root reinforcement between tree species, 3) root reinforcement is maximized by birch and pine when growing in freely drained, cohesionless sandy soil, and 4) further study of birch genecology is needed to identify generalist, high performing populations such as Skeena. Overall, managing for mixedwoods in BC has both ecological and economical benefits, including enhanced slope stability.

Download or read book Genecology of 20 Paper Birch Betula Papyrifera Marsh Provenances from British Columbia and Northern Idaho written by Nicole Balliet and published by . This book was released on 2009 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Paper birch is an ecologically valuable species with a broad geographic distribution and increasingly valuable commercial attributes. Its diversity, versatility and enduring nature make it an ideal candidate for a selective breeding program. However, an understanding of the genecology of the species and an understanding of the potential impacts of climate change will be fundamental to its success. The objectives of the trail were to determine if the phenotypic variability observed in paper birch for certain traits was due to genetics, the growing environment or an interaction between the two. Traits examined were bud flush (phenological) and height growth (morphological). Whether or not nursery practices were a factor was also examined. Twenty provenances of paper birch were collected from five regions in British Columbia (BC) and northern Idaho. Seedlings were grown at three nurseries in BC and Idaho and planted in a randomized single tree interlocking block design in three common gardens in BC and Idaho. Geographic variation in the timing of bud burst in paper birch is under genetic and environmental control. It follows climatic clines based on latitude, longitude and elevation. The signal for the onset of spring bud flush is determined by an interaction between air and soil temperature and photoperiod. Long distance displacement of provenances from their site of origin can lead to detrimental abiotic and biotic effects such as frost or pest damage. Differences in stock handling among nurseries and nursery displacement effects also influenced the growth and survival of some provenances. This information will be useful when developing seed zones and seed transfer guidelines for paper birch in BC. It will also help mitigate the potential impacts of climate change and will be beneficial if a selective breeding program is established.
