Book excerpt: 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 excerpt: 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.

This book was released on 2018-05-03 with total page 20 pages. Available in PDF, EPUB and Kindle. 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.

Download or read book Fundamentals of Tree Ring Research written by James H. Speer and published by University of Arizona Press. This book was released on 2021-11-30 with total page 360 pages. Available in PDF, EPUB and Kindle. Book excerpt: Tree-ring dating (dendrochronology) is a method of scientific dating based on the analysis of tree-ring growth patterns. As author James Speer notes, trees are remarkable bioindicators. Although there are other scientific means of dating climatic and environmental events, dendrochronology provides the most reliable of all paleorecords. Dendrochronology can be applied to very old trees to provide long-term records of past temperature, rainfall, fire, insect outbreaks, landslides, hurricanes, and ice storms--to name only a few events. This comprehensive text addresses all of the subjects that a reader who is new to the field will need to know and will be a welcome reference for practitioners at all levels. It includes a history of the discipline, biological and ecological background, principles of the field, basic scientific information on the structure and growth of trees, the complete range of dendrochronology methods, and a full description of each of the relevant subdisciplines. Individual chapters address the composition of wood, methods of field and laboratory study, dendroarchaeology, dendroclimatology, dendroecology, dendrogeomorphology, and dendrochemistry. The book also provides thorough introductions to common computer programs and methods of statistical analysis. In the final chapter, the author describes "frontiers in dendrochronology," with an eye toward future directions in the field. He concludes with several useful appendixes, including a listing of tree and shrub species that have been used successfully by dendrochronologists. Throughout, photographs and illustrations visually represent the state of knowledge in the field.
