This book was released on 1988 with total page 28 pages. Available in PDF, EPUB and Kindle. Book excerpt: Mixed-conifer forests are the largest vegetation type in California, covering more than 13 million acres (Barbour and Major 1977). This type, the Sierra Nevada Mixed Conifer (Society of American Foresters Forest cover type 243, Tappeiner 1980) dominates mid-elevations of the Sierra Nevada's western slopes. The extent of the mixed-conifer type and the amount of timber harvested from the west slopes of the Sierra Nevada emphasize the need for accurate growth and yield prediction methods for this area.

This book was released on 1988 with total page 16 pages. Available in PDF, EPUB and Kindle. Book excerpt: Estimates of forest growth (increment) are used for evaluating productivity of land and to project growing stock into the future. Since volume is the accepted parameter for measuring forest growth (Spurr 1952), estimates of periodic volume increment for individual trees on inventory plots form the basis for appraising the productivity of the land and timber.

This book was released on 2003 with total page 344 pages. Available in PDF, EPUB and Kindle. Book excerpt: "A growth model was developed for multiaged mixed-conifer forests in the Sierra Nevada of California. The model incorporates process-oriented components that predict tree growth as a function of leaf area and absorbed light, as well as empirical information on site quality. Leaf area prediction equations were developed from sapwood area--leaf area relationships for Pinus ponderosa Laws., Abies concolor Gordon and Glend., Calocedrus decurrens (Torrey) Florin, Pseudotsuga menzieii var. menziesii (Mirb.) Franco, Pinus lambertiana L., and Quercus kelloggii Newb. Inclusion of site index improved model predictions across the range of sites sampled in the Sierra Nevada. Leaf area was used to calibrate a spatially explicit light model to conditions in the Sierra Nevada. The light model was able to predict the variable light environment within complex canopy structures. Moreover, it showed little loss in accuracy when model parameters were simplified for use of the model with inventory data. The model calculates light at any point within the canopy and can estimate mean incident and absorbed light of larger tree crowns. Boundary line analysis showed that the maximum amount of leaf area a tree maintained depended upon the mean light received over the growing season and differed among species. Tree growth efficiency, defined as stem volume increment per unit of leaf area, was correlated with tree size and light environment. Growth efficiency increased with tree height across the range of light intensity levels. Prediction equations were developed for volume increment as a function of projected leaf area and leaf area weighted by absorbed light. These relationships demonstrate the varying importance of shading and self-shading on tree growth in vertically structured stands. Additional models for height, basal area, and crown radial increment were developed to project volume increment and stand structural development over periods of up to 20 years. The whole model was validated with independent permanent sample plot data from two multiaged mixed-conifer stands. It can be used to assess the effects of stand structure upon stand and component yield and structural development. The model is intended to be a tool for managers to design multiaged mixed-species stands of variable structure."--Abstract.

This book was released on 1981 with total page 4 pages. Available in PDF, EPUB and Kindle. Book excerpt: Tree diameter outside bark at an earlier period of growth can be estimated from the linear relationship of present inside bark and outside bark diameters at breast height. This note presents equations for estimating inside bark diameters, outside bark diameters, and past outside bark diameters for each of the mixed-conifer species in the central Sierra Nevada.

This book was released on 1984 with total page 4 pages. Available in PDF, EPUB and Kindle. Book excerpt: The linear relationship of inside to outside bark diameter at breast height provides a basis for estimating diameter inside bark from diameter outside bark. Estimates of diameter inside bark and past diameter outside bark are useful in predicting growth and yield. During field seasons 1979-1982, data were obtained from stem analysis of 931 trees in young-growth stands of the mixed-conifer type on the westside Sierra Nevada of California. Species included were coast Douglas-fir, California white fir, incense-cedar, sugar pine, ponderosa pine, and Jeffrey pine. This note provides equations for estimating inside bark diameters, double bark thickness, and past outside bark diameters for each of the species studied.
