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 (

Download or read book A Field Guide to Site Identification and Interpretation for the Southeast Portion of the Prince George Forest Region written by C. DeLong and published by British Columbia, Forest Science Program. This book was released on 2003 with total page 276 pages. Available in PDF, EPUB and Kindle. Book excerpt: This guide has two main goals: to assist users in classifying sample forest ecosystem sites in the field in the south-east Prince George Forest Region; and to provide interpretations for these site units that will assist in preparing management prescriptions. Following the introduction is a brief discussion of the biogeoclimatic classification system. Chapter 3 contains procedures for site description, identification, mapping, & interpretation. Chapters 4 to 11 present information about the biogeoclimatic units in the Region, tools for identification of biogeoclimatic & site units, descriptions of the site units, and direct management interpretations for the identified site units. Chapter 12 provides indirect interpretations for silvicultural systems and site preparation options, as well as some basic information on ecosystem management.

Download or read book Field Guide to the Autecology of Selected Crop Trees and Competitor Species in Northeastern Ontario written by R. W. Arnup and published by Timmins, Ont. : Northeast Science & Technology. This book was released on 1995 with total page 182 pages. Available in PDF, EPUB and Kindle. Book excerpt: This manual contains information on seven commercially important tree species and on 44 plant species that may compete with these crop tree species in northeastern Ontario. The introduction provides background information for the species comparison tables and species summaries that follow, and explains the format of the manual. The tables give information on each species' autecology in the context of the Forest Ecosystem Classification (FEC) system for northeastern Ontario. In addition, each potential competitor is evaluated with respect to their competitive effects and mechanisms, their response to disturbance and silvicultural treatments, and their potential value for wildlife. The crop tree species are evaluated with respect to their response to competition and their ability to respond to release. Line diagrams are included to aid in field recognition. The appendix contains a glossary and a key to FEC names and descriptions.
