This book was released on 2011 with total page 60 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Mount Tom adaptive management trial was initiated in 1999 on 4067 hectares in mountain caribou (Rangifer tarandus caribou) winter habitat in east-central British Columbia. It builds on and expands knowledge gained from the Quesnel Highland Alternative Silvicultural Systems trial, set up further to the south in 1990, to explore options to maintain caribou habitat while allowing for some forest harvesting. The principal objective of the Mount Tom adaptive management trial is to examine the effects of applying partial cutting, in a range of ecological and geographical contexts, at the operational level. The purpose of this establishment report is to document the study area, layout, and methods associated with the many studies embedded in this long-term, complex trial. Specifically, this report describes studies designed to measure the response of arboreal lichens to partial cutting; describe the pre-harvest stand structure and monitor the post-harvest stand development; measure the treefall rates on opening edges and within the residual forest; measure the response of Engelmann spruce and subalpine fir regeneration in a range of opening sizes, ecotypes, site preparation and microsite planting options; monitor the vegetation development in openings; determine the effects of the group selection treatment on snow accumulation and snow ablation rates; and monitor the microclimate. This report also describes the harvesting operations and extension opportunities in the trial.--Document.

Research Section and published by . This book was released on 2000 with total page 6 pages. Available in PDF, EPUB and Kindle. Book excerpt: Mountain caribou winter habitat in the Cariboo Forest Region is found primarily at elevations above 1400 m in mature and old Engelmann spruce / subalpine fir (Picea englemanii / Abies lasiocarpa) forests that have abundant arboreal lichens. Arboreal lichen is the major food source for caribou during winter months. Most of the winter range habitat in the Cariboo Forest Region falls within the ESSFwc biogeoclimatic subzone with a smaller portion at high elevations of the ESSFwk. Clearcutting has been the most common silvicultural system used in these ecosystems. However, it removes the entire arboreal lichen source and more than 100 years will be required for a clearcut patch to provide adequate lichen forage for caribou. As a result, a harvested area managed under normal rotations may never provide suitable caribou habitat. Research was initiated as early as 1989 in the Cariboo Forest Region to study silvicultural systems that would maintain mountain caribou habitat. Research efforts have focused on the replicated trial (E.P. 1104.02) where numerous studies have been completed. The remainder of this report will discuss regeneration, microclimate and windthrow results. This trial also includes studies concerning stand structure, lichen abundance and distribution, lichen growth, breeding bird communities, small mammal communities, and snow distribution and melt, which will not be reported here.

Book Synopsis Development and Structure of Three High-elevation Old Spruce-fir Stands in the Quesnel Highland of East-central British Columbia by : O. A. Steen
Download or read book Development and Structure of Three High-elevation Old Spruce-fir Stands in the Quesnel Highland of East-central British Columbia written by O. A. Steen and published by University of British Columbia Press. This book was released on 2005 with total page 48 pages. Available in PDF, EPUB and Kindle. Book excerpt: This study describes the composition, size and age structure, and development of three old Engelmann spruce-subalpine fir stands at high elevations (>1500 m) in the Quesnel Highland in east-central British Columbia. The descriptions provide a basis for designing alternative silvicultural systems that will maintain usable old-forest habitat for mountain caribou and other old-growth-dependent species. Subalpine fir, which comprised 86% of all stems in the three stands, had inverse-J-shaped size and age profiles. Engelmann spruce included the largest trees in each stand but had bimodal size and age profiles. Age structure interpretations suggest that the stands have developed over periods of about 290-450 years since the last major stand-level disturbances (probably wildfires). Current stand age structures contain no clear evidence of post-establishment stand-level disturbances, although the data do not exclude the possibility of such disturbances. Approximately 29% of the fir trees and 13% of the spruce trees were dead. Age analyses of the tree seedling banks in the three stands indicate stable populations with continuous recruitment during the last 40 years. Young seedlings occurred preferentially on woody debris in advanced stages of decay, suggesting that seedling density differences among stands may be due at least partially to differences in the amount of woody debris. The stand that apparently had the shortest time (about 290 years) for development since major disturbance had a structure that was still adjusting to disturbance. Evidence of this adjustment includes a bimodal fir age distribution and a high density of small trees that are apparently undergoing thinning. In addition, this stand had very few large (>60 cm dbh) live or dead trees and low volumes of coarse woody debris, especially in large and well-decomposed pieces, compared to the other two stands. A comparison of the three stands in this study suggests that naturally established high-elevation forests of the ESSFwc3 may not achieve some old-growth attributes, such as large dead trees and large, well-decomposed woody debris, until 400 or more years following initiation. The two stands in this study with the longest period of development (at least 450 years) had balanced size and age structures and well-represented old-growth attributes such as large dead trees and large, well-decayed woody debris. Planted stands may achieve some ESSFwc3 old-growth features several decades sooner than natural stands, due to a shorter stand initiation period. The alternative silvicultural system that has been proposed for maintaining suitable mountain caribou habitat following harvesting in this area (group selection system with 240-year rotation) will likely result in stands with many old-growth features, including abundant arboreal lichens. Some features that may not be present in these stands include a uniform inverse-J age distribution, many large (>60 cm dbh) live and standing dead trees, and large-diameter, well-decayed woody debris. As old stands in the ESSFwc3 continue to age without outside disturbance, the spruce component of the stands will likely decline. Partial harvesting would help to maintain a significant component of spruce in these stands.

This book was released on 1973 with total page 134 pages. Available in PDF, EPUB and Kindle. Book excerpt: The current trend toward the establishment and care of forests for a wide combination of uses requires flexibility in forest culture and a knowledge of the silvicultural choices available to the resource manager. This publication summarizes for each of 37 major forest types in the United States the silvicultural systems that appear biologically feasible on the basis of present knowledge. Supporting information is given on the occurrence of the 37 forest types, the cultural requirements of the component species, and the biological factors that control the choice of silvicultural options. The text is arranged in regional sections suitable for reprinting.

Download or read book Microclimate Studies in Silvicultural Systems on the Chilcotin Plateau of British Columbia written by Robert Matthew Sagar and published by . This book was released on 2005 with total page 40 pages. Available in PDF, EPUB and Kindle. Book excerpt: Group selection and irregular group shelterwood silvicultural systems are being tested as options to conserve woodland caribou (Rangifer tarandus caribou) habitat. If successful, the systems will be applied within the very dry, cold Sub-Boreal Pine-Spruce (SBPSxc) and very dry, very cold Montane Spruce (MSxv) biogeoclimatic subzones, located on the high-elevation Chilcotin Plateau of west-central British Columbia. In these harsh growing environments, partial cutting strongly influences the microclimate in terms of air and soil temperature, frost events, and snow-free dates. To examine the magnitude of this influence, three pairs of climate stations were set up in partial cuts and clearcuts, across a range of elevations, to compare microclimate conditions. The study also compared north edge, centre, and south edge microsites within one 30-m opening on each of three partial cuts.

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.
