Stand tending impacts on environmental indicators by Julee A Greenough( Book )

6 editions published in 1996 in English and held by 48 WorldCat member libraries worldwide

Stand tending refers to a variety of forest treatments that can be used to enhance timber production, including pruning, fertilizing, and pre-commercial and commercial thinning. Stand tending changes the structure of a forest stand and can have both negative and positive effects on habitat and wildlife. Quantitative data on these environmental costs and benefits are needed to optimize the level of investment in stand tending and to direct that investment where it will to the most good. This study uses the Tree and Stand Simulator (TASS) to forecast the changes in stand structure following stand tending. Environmental indicators sensitive to changes in stand structure were identified and their structural dependencies were quantified, then coupled to TASS output to show how the indicators were expected to change over time under 89 different stand tending regimes. Results presented indicate the environmental trade-offs associated with stand tending and also the dependence of net effects of stand treatment not only on stand conditions after treatment but also on the rotation length chosen with that treatment. Two examples are provided to show how stand-level environmental indicators can contribute to the landscape-level analyses required for management planning for the maintenance of biodiversity
Seedling barrier protection from deer and elk browse by Ian Booth( Book )

4 editions published in 1996 in English and held by 14 WorldCat member libraries worldwide

Discusses the methods of detecting and assessing deer and elk browse problems, and describes possible methods of protecting seedlings from browse damage using physical protection devices. The publication is intended for use by foresters and forest technicians concerned with minimising deer and elk browse damage to commercial trees. It includes information on the types of trees preferred by deer and elk in British Columbia, tree shelters, fencing, site characteristics affecting the selection of protection methods, and cost comparisons of various methods of seedling protection. Concludes with descriptions of selected deer and elk browse protection project sites in British Columbia. The appendix includes a directory of manufacturers and distributors of seedling protection products

Public health and environmental impacts of monosodium methanearsonate as used in bark beetle control in British Columbia by Frank N Dost( Book )

3 editions published in 1995 in English and held by 13 WorldCat member libraries worldwide

Monosodium methanearsonate (MSMA) is used in British Columbia to create lethal trap trees for control of bark beetle infestation. The average annual total area of treatment in the province is 650 hectares, dispersed over a wide range covering most of the interior where bark beetle infestations may occur. This report assesses the impacts of MSMA use, including its behavior and fate in the environment when used for forest insect control, the toxicology of MSMA and its toxicity to humans and to terrestrial and aquatic species, the routes by which MSMA may be ingested by humans, and the extent of exposure to MSMA from treated trees, including exposure to sawdust and smoke. The report concludes with an assessment of the MSMA health risk, including graded or consistent effects and the risk of systemic toxicity. A glossary and a MSMA material safety data sheet are included

The Introduction to forest health( Visual )

3 editions published between 1995 and 1996 in English and held by 10 WorldCat member libraries worldwide

Looks at four examples of tree damage caused by Douglas-fir bark beetle; western spruce budworm; root disease; and deer browsing. With each example, forest health professionals describe the action taken to prevent or reduce damage and loss
Fundamentals of natural lodgepole pine regeneration and drag scarification by Bryce Bancroft( Book )

1 edition published in 1996 in English and held by 10 WorldCat member libraries worldwide

Provides a method for predicting the success of natural regeneration of lodgepole pine based on key aspects of lodgepole pine reproductive biology, critical planning steps for natural lodgepole pine regeneration and post harvest assessment data collection
Sawnwood values and species effects on quality : an historical perspective for British Columbia by S. G Feltham( Book )

4 editions published in 1996 in English and held by 9 WorldCat member libraries worldwide

A review of sawnwood price studies as well as the use of a new data set to calculate historical price changes and a wood quality index for B.C. and Canada is presented. The data are used to calculate average annual rates of real price change. A review of previous studies on historical price growth rates and projected future rates is also presented. The range of price growth rates reported may be used as a reference when conducting financial sensitivity analyses of silviculture activities
Behaviour of site index estimates when a growth intercept model is applied in surveys of regenerated stands : examples from a study of stumped, coastal Douglas-fir stands by Patrick Martin( Book )

2 editions published in 2001 in English and held by 6 WorldCat member libraries worldwide

Growth intercept models are used widely in British Columbia to estimate site index in young stands. These models were introduced in their current form in 1995 (Nigh 1995). As growth intercept models are relatively new to BC, most silviculturists are unfamiliar with the typical characteristics of the site index estimates produced by these models. In this paper, we use data collected in a recent study to demonstrate some important characteristics of the site index estimates of growth intercept models when they are applied in surveys of regenerated stands. This paper is intended to help silviculturists using the growth intercept models to: become more familiar with some key characteristics of the models; better assess how the models are performing; improve the accuracy of site index estimates; reduce sampling costs and increase sampling efficiency
Saving berries for the bears( Book )

2 editions published in 1996 in English and held by 6 WorldCat member libraries worldwide

The nutrient-rich valleys of coastal mainland British Columbia contain some of the most productive sites in the world for growing large conifer trees. These same valleys also support some of Canada's highest concentrations of grizzly bears. The grizzlies are attracted to the abundant berry-producing shrubs and other vegetation found in the floodplains, skunk cabbage swamps, and lower side slopes of coastal valleys. The moist, rich soils of the valley bottoms provide an excellent environment for a variety of important grizzly bear forage species--red elderberry, currents, salmonberry, red-osier dogwood, devil's club and skunk cabbage. After a coastal valley bottom is logged, many of the plants that grizzlies feed on are among those that compete for growing space and sunlight with regenerating tree seedlings. This competition for limited resources can make it difficult to re-establish a new crop of commercial trees. As a result, silviculturists often use herbicides or manual methods to control the growth and spread of competing vegetation. These pages describe an adaptive forest management process designed to maintain and restore important grizzly bear habitat while continuing to produce high-value timber
Site preparation for establishing lodgepole pine on backlog sites in the sub-boreal spruce zone( Book )

2 editions published in 2001 in English and held by 6 WorldCat member libraries worldwide

Several major silvicultural trials were initiated in the 1980s in the northern interior of British Columbia to evaluate site preparation techniques and stock options for establishing coniferous plantations on backlog not satisfactorily restocked forest land. Results are reported here from two such trials (Doris Lake and Kluskus) involving lodgepole pine (Pinus contorta Dougl. var. latifolia Engelm.) in the Sub-Boreal Spruce Zone
Controlling weeds using biological methods by British Columbia( Book )

1 edition published in 1996 in English and held by 4 WorldCat member libraries worldwide

The Ministry of Forests is responsible for the maintenance and improvement of forest and rangeland in B.C.A major problem threatening the productive capability and ecology of some land administered by the Ministry of Forests is the invasion of noxious weeds. Noxious weeds are plants out of place. Many noxious weeds have been unintentionally introduced into B.C., often from Europe and Asia. They do not naturally occur here. As a result, their natural enemies, which would have evolved with them in their homeland, are not here. Without natural enemies, these plants have reproduced and spread extensively. Biological control of noxious weeds in B.C. uses plant-specific insects to reduce the number of weeds. This document covers the biological control program in B.C., selecting suitable biological control agents, ensuring agents can be safely introduced in North America, preparing biological control agents for release, and releasing and monitoring agents in the field. It includes a summary of biological control releases in B.C
