Book Developing a Hybrid Growth Model for Multiaged Sierra Nevada Mixed conifer Forests

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 Predicting Height Increment of Young growth Mixed Conifers in the Sierra Nevada

Download or read book Predicting Height Increment of Young growth Mixed Conifers in the Sierra Nevada written by K. Leroy Dolph and published by . 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 Patterns and Processes in Forest Landscapes

Download or read book Patterns and Processes in Forest Landscapes written by Raffaele Lafortezza and published by Springer Science & Business Media. This book was released on 2008-08-30 with total page 434 pages. Available in PDF, EPUB and Kindle. Book excerpt: Increasing evidence suggests that the composition and spatial configuration – the pattern – of forest landscapes affect many ecological processes, including the movement and persistence of particular species, the susceptibility and spread of disturbances such as fires or pest outbreaks, and the redistribution of matter and nutrients. Understanding these issues is key to the successful management of complex, multifunctional forest landscapes, and landscape ecology, based on a foundation of island bio-geography and meta-population dynamic theories, provides the rationale to deal with this pattern-to-process interaction at different spatial and temporal scales. This carefully edited volume represents a stimulating addition to the international literature on landscape ecology and resource management. It provides key insights into some of the applicable landscape ecological theories that underlie forest management, with a specific focus on how forest management can benefit from landscape ecology, and how landscape ecology can be advanced by tackling challenging problems in forest (landscape) management. It also presents a series of case studies from Europe, Asia, North America, Africa and Australia exploring the issues of disturbance, diversity, management, and scale, and with a specific focus on how human intervention affects forest landscapes and, in turn, how landscapes influence humans and their culture. An important reference for advanced students and researchers in landscape ecology, conservation biology, forest ecology, natural resource management and ecology across multiple scales, the book will also appeal to researchers and practitioners in reserve design, ecological restoration, forest management, landscape planning and landscape architecture.
