The British Columbia Forest Practices Code creates a legal requirement for soil conservation and, in particular, calls for skid road rehabilitation to restore site productivity & site hydrology. This report presents the seven-year results of a research trial initiated in the Nelson Forest Region in 1985 to test the efficacy of rehabilitation practices by quantifying tree growth on rehabilitated skid roads. Sites were planted with lodgepole pine, Engelmann spruce, or both. At eight locations in the Rocky and Purcell mountains, total height, annual height increment, and basal diameter were measured on 1,713 trees ranging in age from six to ten years. Comparisons are made between growth of undisturbed trees and those on various locations on the rehabilitated berm. Based on the results, recommendations are made regarding improvements to skid road rehabilitation.

This report summarizes issues and problems in forest soil rehabilitation in British Columbia, presenting an up-to-date review of the scientific literature and the activities of rehabilitation specialists and practitioners working for the forest industry and government. The focus is on techniques for restoring soil productivity, with the implied objective of re-establishing a productive forest ecosystem on a site that has suffered degradation. The first two sections of the report provide an overview of soil rehabilitation in the province and review the productivity of degraded and rehabilitated forest soils. This is followed by a section on soil physical process and nutrient cycling, describing how an understanding of growth-limiting conditions can guide practitioners to strategies for effective and cost-efficient rehabilitation. The next section reviews rehabilitation techniques, including tillage, topsoil conservation and replacement, reforestation and revegetation methods, and soil amelioration using fertilizers, amendments, and mulches. Finally, information gaps and research needs are identified.

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.

The Elk Valley coalfield is one of three structurally separate coalfields in southeastern British Columbia which together comprise the East Kootenay coalfields. This study used mapping, measurement of stratigraphic sections, core logging, coal sampling, grab sampling and channel sampling in the field, laboratory analysis of coal and pellets, and structural analysis to provide information on stratigraphy, tonsteins, coal seam maceral compositions, structural geology, coal rank distribution, and coal quality.

Adaptive Environmental Assessment And Management written by C. S. Holling and has been published by this book supported file pdf, txt, epub, kindle and other format this book has been release on 1978 with Nature categories.
This book develops an adaptive approach to environmental impact assessment and management and is based on a study initiated by a workshop convened in early 1974 by SCOPE (Scientific Committee on Problems of the Environment). CS Holling discusses the nature and behavior of ecological systems and its issues, limitations, and potential of environmental assessment. Further, he discusses how we can incorporate impact assessment studies with actual environmental planning and decision making.Crawford Holling received his B.A. and M.Sc. at the University of Toronto (1952) and his Ph.D. at the University of British Columbia (1957). He worked in the laboratories of the Department of the Environment, Government of Canada. Since then, he has been, at various times, Professor and Director of the Institute of Resource Ecology, University of British Columbia, Vancouver, Canada, and Director of the International Institute for Applied Systems Analysis (IIASA), Vienna, Austria. He now occupies the Arthur R. Marshall Jr. Chair in Ecological Sciences at the University of Florida and has launched a comparative study of the structure and dynamics of ecosystems.
