Download or read book Brushing and Grazing Effects on Lodgepole Pine Vascular Plants and Range Forage in Three Plant Communities in the Southern Interior of British Columbia written by Suzanne Simard and published by University of British Columbia Press. This book was released on 1998 with total page 76 pages. Available in PDF, EPUB and Kindle. Book excerpt: A series of research trials established in 1986-87 in the Kamloops Forest Region, British Columbia, studied the effectiveness of chemical and manual treatment methods for controlling competing vegetation, and also studied the impact that these brushing methods had on the range resource in the region. This report first describes the study methodology, including site selection, experimental design, measurements made, and statistical analyses. It then reports the results of the three studies in the series: the effects of brushing and grazing on lodgepole pine, the dry alder plant community, and range forage at the Devick Lake site; effects of brushing and grazing on lodgepole pine, the willow plant community, and range forage at the Ellis Creek site; and effects of brushing on lodgepole pine, the pinegrass plant community, and range forage at the Upper McKay Creek site.
Download or read book Effects of Operational Brushing on Conifers and Plant Communities in the Southern Interior of British Columbia written by Suzanne Simard and published by . This book was released on 2001 with total page 428 pages. Available in PDF, EPUB and Kindle. Book excerpt: This handbook contains information on the effects of operational brushing treatments on conifers & plant communities in the Kamloops and Nelson forest regions of British Columbia. Data were collected over a nine-year period from 96 individual PROBE (PRotocol for Operational Brushing Evaluations) trials. The first three sections present an introduction to the PROBE program, its objectives, and the research methodology. Sections 4 to 11 contain detailed analyses for eight vegetation complexes (fireweed, fern, mixed shrub, ericaceous shrub & subalpine herb, dry alder, wet alder, aspen, and mixed broadleaf/shrub complex). Each of these sections contains an abstract, an introduction, site descriptions, results, discussion, conclusions, and management implications. The final section is an overall summary and management recommendation. Appendices include information about the willow and pinegrass complexes, a summary of results for unreplicated treatments involving those communities, and summary tables of information about PROBE sites that presently represent unreplicated treatment cells.

Download or read book The Effects of Site Preparation and Harvesting Practices on Planted Seedling Productivity and Microenvironment in Southern Interior Dry Grassy IDF Forests written by Jean Heineman and published by . This book was released on 2003 with total page 32 pages. Available in PDF, EPUB and Kindle. Book excerpt: Dry, pinegrass-dominated sites in the interior Douglas fir (IDF) zone of southern interior British Columbia are challenging to regenerate, despite ongoing improvements in nursery & silviculture practices. Using results from three separate studies, this report discusses conifer seedling survival & growth responses to silvicultural systems & site preparation treatments that were applied to relieve harsh site conditions at Fehr Mountain, Murray Creek, and Opax Mountain. To help interpret these responses, the effects of silvicultural system & site preparation treatments on seedling microenvironment are also analyzed with reference to the following factors: soil water, air temperature, soil temperature, light, nutrient availability, soil physical properties, and ectomycorrhizae.

Download or read book Managing Ingrown Douglas fir Stands for Biodiversity Forage and Timber written by O. A. Steen and published by University of British Columbia Press. This book was released on 2008 with total page 34 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Farwell Canyon project was established to explore treatment options for enhancing undergrowth vegetation cover, forage production, and tree growth in densely ingrown Douglas-fir stands of the Interior Douglas-fir very dry mild (IDFxm) biogeoclimatic subzone. Fire scar and tree age analyses along with stand structure observations suggest that many of these ingrown stands were considerably more open before European settlement. Stem reduction treatments applied to two ingrown sites in 200 included logging only (L), logging plus juvenile thinning (LT), and logging plus thinning plus underburning (LTB). No-treatment (NT) areas were also established. The logging treatment was modified from standard practices to harvest small merchantable stems and to initiate thinning of juvenile stems. The objective of this report is to compare third- and fifth-year (2003 vs. 2006) vegetation composition, forage production, and tree regeneration responses to these treatments on one site. Douglas-fir regeneration density increased in all treatments between 2003 and 2006. Cover of grasses increased substantially, due primarily to increased cover of pinegrass (Calamagrostis rubescens). The number of plots with bunchgrasses increased even though mean cover of bunchgrasses did not increase significantly. Shrub and forb cover remained generally low on all treatments. Biomass of combined forbs and graminoids increased significantly from 2003 to 2006 but did not differ significantly among treatments. These early results suggest that the logging treatment, with or without additional treatments, is leading to increased vascular plant cover and forage production. Tree regeneration density is still relatively low. The thinning and underburning treatments have reduced the fire hazard and prepared the stand for follow-up treatments to maintain a more open stand structure. The stand treatments applied in this study should be combined with other treatments to create various stand structures across the IDFxm landscape,corresponding to historic variability of disturbances within the IDFxm subzone.

Download or read book Ecological Regions of North America written by and published by . This book was released on 1997 with total page 92 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume represents a first attempt at holistically classifying and mapping ecological regions across all three countries of the North American continent. A common analytical methodology is used to examine North American ecology at multiple scales, from large continental ecosystems to subdivisions of these that correlate more detailed physical and biological settings with human activities on two levels of successively smaller units. The volume begins with an overview of North America from an ecological perspective, concepts of ecological regionalization. This is followed by descriptions of the 15 broad ecological regions, including information on physical and biological setting and human activities. The final section presents case studies in applications of the ecological characterization methodology to environmental issues. The appendix includes a list of common and scientific names of selected species characteristic of the ecological regions.
