In 2006, a total of 360 lodgepole pine trees were destructively sampled from 45 sites that had been killed by mountain pine beetle (Dendroctonous ponderosae Hopk.). The trees were sampled from the Sub Boreal Spruce (SBS) Biogeoclimatic zone within north central British Columbia. The trees were distributed evenly across the geographic areas as well as across a sample matrix that included three classes of time since death, three classes of diameter at breast height, and three classes of soil moisture regime. A previous report described the procedures used to the collect the data and summarized the data collected for each of the sample trees. The current study analyzes the data and presents a detailed assessment of the changes in the wood quality attributes of mountain pine beetle-killed trees that occur within 5 years since death.--Includes text from document.

With sixty descriptive maps and accompanying text, The Biodiversity Atlas of British Columbia provides a broad overview of the province?s range of terrestrial and freshwater biological diversity. Bringing together data from numerous sources summarized in map form, the Atlas provides a window to B.C.?s diverse ecosystems, the species that live in them, and the elements of British Columbia?s biodiversity that make it globally significant. The Atlas also presents a visual perspective of a number of human-induced threats, including climate change, affecting biodiversity in B.C. today. The Atlas is designed to serve as a companion document to Taking Nature?s Pulse: The Status of Biodiversity in British Columbia ? a comprehensive scientific assessment of biodiversity in the province. Both the Atlas and Taking Nature?s Pulse are projects of Biodiversity BC, a partnership of conservation groups and government agencies.

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.

This project was developed to identify a set of risk indicators to predict the risk of summer-ground loss at the watershed level within the Vanderhoof Forest District (VFD) and others, subsequent to the mountain pine beetle (MPB) infestation of lodgepole pine stands. This report was done in relation to the VFD annual cut of stands, and the following difficultings that operators found in running their equipment in wet versus dry soils in harvest years. Risk indicators were selected from available GIS information, aerial photographs, and local knowledge. The most effective indicators for predicting the risk of wet-ground areas at the watershed level were found to be lodgepole pine content, understorey, drainage density, sensitive soils, and the topographic index, all of whose values are available from provincial databases. The work includes information on materials and methods, results and discussion, the authors' conclusions, as well as recommendations.--Includes text from document.
