Book Assessment of Silvicultural Systems Developed for Deep Snowpack Mule Deer Winter Range in the Central Interior of B C

Download or read book Assessment of Silvicultural Systems Developed for Deep Snowpack Mule Deer Winter Range in the Central Interior of B C written by M. J. Waterhouse and published by British Columbia Forest Science Program. This book was released on 2005 with total page 56 pages. Available in PDF, EPUB and Kindle. Book excerpt: "In the central interior of British Columbia (Southern Interior Forest Region), Douglas-fir (Pseudotsuga menziesii) tends to occur in even-aged stands in the Interior Cedar-Hemlock Moist, Cool, Horsefly biogeoclimatic variant (ICHmk3). Douglas-fir stands are important from both forest industry and wildlife habitat management perspectives. Mule deer require mature and older Douglas-fir stands as winter range. In these ecosystems, Douglas-fir stands are typically clearcut, thereby seriously compromising habitat value as winter range. This is a pilot study to examine the response of vegetation (percent cover) and Douglas-fir regeneration (density and growth) to a range of opening sizes, opening orientation (along and across contours), and site preparation treatment (yes or no), 5 years post-harvest. The openings (15 165 m [0.25 ha], 30 165 m [0.5 ha], 60 165 m [1.0 ha], 60 330 m and 140 140 m [2.0 ha]) are options for group selection, patch cut, or clearcut silvicultural systems. Although most of the 19 tree, shrub, and grass species that mule deer could eat did not change in percent cover from pre-harvest to 5 years postharvest, the species that did change were most strongly affected by harvesting, not opening size. A major diet component, western redcedar (Thuja plicata), was reduced from 9.6 to 1.4% in the site-prepared openings, and from 9.4 to 3.9% in the openings not site-prepared, when comparing the pre-harvest to the 5th-year post-harvest assessment. However, in the 5 years since harvesting, this species has increased from 533 stems per ha to 783 stems per ha (47%) and should increase steadily in cover over time. Of note was a big increase in red raspberry (Rubus idaeus) (from 0.1% up to 14%) and a moderate increase in birch-leaved spirea (Spirea betufolia) (from 1% up to 6%); however, they generally occur in small amounts (

Book British Columbia s Inland Rainforest

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.

Book Snow Interception in Response to Forest Stand Attributes on Mule Deer Winter Ranges in Dry belt Douglas fir Forests in the Central Interior of British Columbia

Download or read book Snow Interception in Response to Forest Stand Attributes on Mule Deer Winter Ranges in Dry belt Douglas fir Forests in the Central Interior of British Columbia written by Rick Dawson and published by . This book was released on 2023 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Snow depth has a critically important influence on mule deer distribution, habitat selection, energy costs, and population levels. Several factors, including forest structure, slope, aspect, elevation, and subregional climate, affect snow depth. Of these factors, forest structure is the only one directly affected by forest management activities such as harvesting, pre-commercial thinning, and road building. Partial cutting in uneven-aged Douglas-fir (Pseudotsuga menziesii) forests in the central interior of British Columbia has produced a range of stand structures.Snow depth and stand attribute data were collected in 1988–1991 from 11 stands with a range of harvest histories. There was a strong relationship between mean snow interception and mean stand attributes, including crown completeness and basal area. Frequency distributions were used to visualize variation in snowpack depth in each stand and help explain the meaning of this variation for deer. Based on 42 winters (1980–2022) of snowpack data from the Environment Canada weather station at the Williams Lake airport, the depth and duration of the snow-pack has not decreased, despite a warming climate, and may be increasing. The results of this study are put in the context of a specialized management system developed to provide for deer habitat and structural diversity at multiple scales on deer winter range in the Cariboo Forest Region. In addition to snow interception, key habitat functions affected by forest structure including security cover, thermal cover, and forage availability are discussed.

Armleder and published by British Columbia, Ministry of Forests Research Program. This book was released on 1998 with total page 11 pages. Available in PDF, EPUB and Kindle. Book excerpt: Describes a specialized low volume removal (20%) single tree selection silvicultural system designed to integrate timber harvesting with the needs of mule deer on interior Douglas-fir winter ranges in central interior BC. The impact of this harvesting was assessed on mule deer during the winter months from 1984-91.

Book Silviculture Treatments for Ecosystem Management in the Sayward STEMS

Download or read book Silviculture Treatments for Ecosystem Management in the Sayward STEMS written by Louise De Montigny and published by University of British Columbia Press. This book was released on 2009 with total page 98 pages. Available in PDF, EPUB and Kindle. Book excerpt: Silviculture Treatments for Ecosystem Management in the Sayward (STEMS) is a large-scale, multi-disciplinary experiment that compares forest productivity, economics, and public perception of seven silvicultural regimes replicated at three sites in the Sayward Forest. The STEMS experiment uses silvicultural systems and treatments to create diversity in forest structure that results in a variety of canopy layers (vertical structure) and spatial patchiness (horizontal structure) to enhance biodiversity and wildlife. This Technical Report describes the establishment of the second replication of STEMS starting in 2003 near Elk Bay in the Sayward Forest. Treatment units were harvested in 2005. STEMS 2 stand conditions differ from STEMS 1 with higher densities and proportions of western hemlock (Tsuga heterophylla) and moister biogeoclimatic site series.--Document.
