This book was released on 2016 with total page 88 pages. Available in PDF, EPUB and Kindle. Book excerpt: In 2008, a Working Group that included British Columbia government staff (researchers, stewardship foresters, and wildlife habitat experts), a research consultant, and industry foresters was formed in the Cariboo Region of south-central British Columbia to determine how existing research concerning conifer#x13;broadleaf competitive relationships could be used to suggest change to free-growing guidelines for that region. The objective was to adjust free-growing criteria concerning broadleaf tree presence in coniferous plantations while maintaining consistency with biological thresholds for conifer growth that had been determined by local research. ...

Download or read book Lodgepole Pine Response to Aspen Removal in Variable Radii in the SBSdw2 Variant Near Williams Lake B C written by Teresa A. Newsome and published by British Columbia, Forest Science Program. This book was released on 2004 with total page 40 pages. Available in PDF, EPUB and Kindle. Book excerpt: Mixed forests of lodgepole pine (Pinus contorta var. latifolia Engelm.) and trembling aspen (Populus tremuloides Michx.) are common throughout interior British Columbia, particularly in north and central areas of the province. In the Cariboo-Chilcotin area of the Southern Interior Forest Region, aspen commonly regenerates along with planted and natural lodgepole pine in the Sub-Boreal Spruce (SBS), Interior Douglas-fir (IDF), Sub-Boreal Pine-Spruce (SBPS), and Interior Cedar-Hemlock (ICH) zones. Historically, aspen has been regarded as a "weed" that competes with conifers, but silviculturists now recognize that there are many benefits to maintaining a broadleaf component within stands. A study was established in 1994 in the SBSdw2 variant of the Cariboo-Chilcotin region of the Southern Interior Forest Region to investigate the effects of removing aspen in 50 or 100 cm radii around crop lodgepole pine versus broadcast removal or no treatment. The primary objective of the study was to assess whether the free-growing criterion (current in 1994), which specified that no overtopping vegetation could be present within a 1 m radius around crop trees, was appropriate in pine-aspen stands, or whether a 50 cm radius zone would be adequate.

Download or read book Physiological Ecology of North American Plant Communities written by Brain F. Chabot and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 704 pages. Available in PDF, EPUB and Kindle. Book excerpt: Although, as W.D. Billings notes in his chapter in this book. the development of physiological ecology can be traced back to the very beginnings of the study of ecology it is clear that the modern development of this field in North America is due in the large part to the efforts of Billings alone. The foundation that Billings laid in the late 1950s came from his own studies on deserts and subsequently arctic and alpine plants, and also from his enormous success in instilling enthusiasm for the field in the numerous students attracted to the plant ecology program at Duke University. Billings' own studies provided the model for subsequent work in this field. Physiological techniques. normally confined to the laboratory. were brought into the field to examine processes under natural environmental conditions. These field studies were accompanied by experiments under controlled conditions where the relative impact of various factors could be assessed and further where genetic as opposed to environmental influences could be separated. This blending of field and laboratory approaches promoted the design of experiments which were of direct relevance to understanding the distribution and abundance of plants in nature. Physiological mechanisms were studied and assessed in the context of the functioning of plants under natural conditions rather than as an end in itself.

Download or read book Forest Hydrology written by Devendra Amatya and published by CABI. This book was released on 2016-09-14 with total page 309 pages. Available in PDF, EPUB and Kindle. Book excerpt: Forests cover approximately 26% of the world's land surface area and represent a distinct biotic community. They interact with water and soil in a variety of ways, providing canopy surfaces which trap precipitation and allow evaporation back into the atmosphere, thus regulating how much water reaches the forest floor as through fall, as well as pull water from the soil for transpiration. The discipline "forest hydrology" has been developed throughout the 20th century. During that time human intervention in natural landscapes has increased, and land use and management practices have intensified. The book will be useful for graduate students, professionals, land managers, practitioners, and researchers with a good understanding of the basic principles of hydrology and hydrologic processes.
