IUFRO The Advocate for Forest Science.
Working Party 2.02.05 brings together all aspects of research in IUFRO on breeding and genetic resources of conifers with natural distributions in North America from British Columbia to northern California (mostly the forests west of the Cascades and Sierra Nevada mountains), but also of economic importance elsewhere. The emphasis is on Douglas fir (coastal and interior), major pines (lodgepole, Ponderosa, western white, Jeffrey and radiata), western hemlock, Abies, Sitka spruce, the cedars, coastal redwood and giant sequoia.
