Book excerpt: Excerpt from Ripening and Dispersal of a Bumper Western Hemlock-Sitka Spruce Seed Crop in Southeast Alaska Western hemlock (tsuga heterophylla (raf.) Sarg.) and Sitka spruce (picea sitchensis (bong.) Carr.) together comprise about 92 percent of the commercial timber volume in southeast Alaska. Both Species are prolific seed producers, with at least some seed produced almost every year and a heavy crop every 5 to 8 years. Seed dispersal from the heavy cone crops of 1951 and 1959 and from the medium cone crop of 1956 has been reported (godman 1953; Harris 1967; James In 1966, a bumper cone crop occurred, offering an opportunity to obtain more detailed information about seed maturation and its dispersal.

Available in PDF, EPUB and Kindle. Book excerpt: Sitka spruce, the largest of the world's spruces, is an important component of British Columbia's coastal forests. Its ecology gives it a special place in the sustainable management of the province's forests. However, in west coast forestry it is poorly known in comparison with its main coniferous companions -- Douglas-fir, western redcedar, and western hemlock. As an important international forestry resource, it is crucial that Sitka spruce -- its ecology and the ecosystems in which it occurs -- be clearly understood by those who are involved with its management.

Book excerpt: Large-scale use of the timber resource of southeast Alaska began in 1953 after long efforts to establish a timber industry. Development and present status of the industry and present management of the timber resource are summarized, stressing the biological basis for timber management activities in southeast Alaska today. Ecological and silvicultural considerations related to timber harvest, reforestation, and stand development are discussed. Published and unpublished information are brought together. Current management practices are discussed as a basis for a better understanding of how this information can be helpful in managing the timber resource and to point out where research is needed.
