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.

Book Synopsis Developing a Hybrid Growth Model for Multiaged Sierra Nevada Mixed-conifer Forests by : Rolf Friedrich Gersonde
Download or read book Developing a Hybrid Growth Model for Multiaged Sierra Nevada Mixed-conifer Forests written by Rolf Friedrich Gersonde and published by . 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.
Book Synopsis Seed Dissemination in Small Clearcuttings in North-central California by : Philip M. McDonald
Download or read book Seed Dissemination in Small Clearcuttings in North-central California written by Philip M. McDonald and published by . This book was released on 1980 with total page 796 pages. Available in PDF, EPUB and Kindle. Book excerpt: In a 1964-1967 study on the Challenge Experimental Forest, seedfall was evaluated in 2-, 5-, and 10-acre circular clearcuttings. During the 4 years, 10 seed crops, ranging from light to bumper, were produced by ponderosa pine. white fir, Douglas-fir, and incense cedar. Seedfall ranged from 76 to 40,691 sound seed per acre (188 to 100,547/ha) for a single species in a given year. From 89 to 100 percent of each species' seed fell within an area 1 1/2 times the height of the average dominant tree. Overall, seed distribution was highly variable.

Book Synopsis Predicting Height to Crown Base for Undamaged and Damaged Trees in Southwest Oregon by : Mark L. Hanus
Download or read book Predicting Height to Crown Base for Undamaged and Damaged Trees in Southwest Oregon written by Mark L. Hanus and published by . This book was released on 2000 with total page 40 pages. Available in PDF, EPUB and Kindle. Book excerpt: Equations for predicting height to crown base are presented for tree species from southwest Oregon. Equations for undamaged and damaged trees were estimated with weighted nonlinear regression techniques. The effects of specific damaging agents on the height to crown base were explored, and damage correction factors were estimated. The damage correction factors can be used to correct the predicted crown ratio for specific damaging agents and their severity in samples where damage is noted. These equations are being incorporated into the new southwest Oregon version of ORGANON (ORegon Growth ANalysis and projectiON), a model for predicting the growth of individual trees in forest stands. The equations extend the past model to older stands and stands with a heavier component of hardwood tree species.
