Book Description
Excerpt from A 4-Year Record of Sitka Spruce and Western Hemlock Seed Fall Beginning in September, seed traps were examined every few days to determine when seed fall started. Thereafter, seed was collected from the traps monthly until February. A final collection was made each year during June or July. Seeds collected from the traps were classified by species and counted. Approximate viability was determined by cutting test, that is, seeds were opened with a razor blade and the cross sections examined; those appearing firm and white were considered viable. 4.

Book Description
Excerpt from Cull Factors for Sitka Spruce, Western Hemlock, and Western Redcedar in Southeast Alaska Within a species the average amount of cull in a tree increases with its age. However, it is impossible or impracticable to determine the age of each sample tree when cruising. Since tree size is ordinar ily correlated with age and is readily measured by cruisers, tree diameter has been employed in the preparation of these cull factors.

Book Description
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.

This information on growth and yield focuses on cause-and-effect relationships rather than on indepth statistical analyses of the data.
