Interior spruce (the white spruce/Engelmann spruce complex) is the most commonly planted tree in British Columbia and has the greatest value to the forest economy of the province. The Ministry of Forests initiated an ambitious breeding program for interior spruce in the late 1960s aimed at producing sufficient quantities of genetically improved seeds to meet demand for forest regeneration. The program started with designating three selection units across the complex, based mostly on biogeoclimatic information. In each unit, desirable phenotypes were selected and their genetic merit was tested in open pollinated progeny trials. This report summarizes 20-year test results on the performance & variability of the selected open-pollinated families in the East Kootenay selection unit. Results are presented regarding height growth, survival rates, diameter, stem volume, and variations in parameters among specific sites in the unit.
A formal task of the Forest Genetic Resources Study Group/North American Forestry Commission/Food and Agriculture Organization of the United Nations and Working Party 2.04.09 / Division 2- Physiology and Genetics /International Union of Forest Research Organizations, this international directory lists more than 1,800 forest geneticists and tree breeders from 86 countries. Each listing includes the entrant's title, mailing address, phone and fax numbers, and email address, when available. Indices organize entrants by country, by alphabetical order, by taxa of interest, and by research subjects.
Climate Change, Human Systems and Policy is a component of Encyclopedia of Natural Resources Policy and Management in the global Encyclopedia of Life Support Systems (EOLSS), which is an integrated compendium of twenty one Encyclopedias. The Theme on Climate Change, Human Systems and Policy presented in three volumes, deals with the interaction between climate and human systems for policy development. These volumes discuss History, Status, and Prediction of Global Climate Change; Potential Large-scale Effects of Global Warming; Public Perceptions Toward Global Climate Change; Effects of Potential Sea-Level Rises; Economics of Potential Climate Change; Response Strategies for Stabilization of Atmospheric Composition; Policy Framework and Systems Management of Global Climate Change. These three volumes are aimed at the following five major target audiences: University and College students Educators, Professional practitioners, Research personnel and Policy analysts, managers, and decision makers and NGOs.
