Available in PDF, EPUB and Kindle. Book excerpt: Functional forms of equations were derived for predicting 10-year periodic height increment of forest trees from height, diameter, diameter increment, and habitat type. Crown ratio was considered as an additional variable for prediction, but its contribution was negligible. Coefficients of the function were estimated for 10 species of trees growing in 10 habitat types of northern Idaho and northwestern Montana.

This book was released on 1992 with total page 12 pages. Available in PDF, EPUB and Kindle. Book excerpt: An equation is given to estimate 10-year height increment for young-growth red fir trees in California and southern Oregon. The independent variables are the individual tree, stand, and site characteristics significantly related to a tree's height growth. Data used to develop the equation came from stem analysis of 492 trees sampled from 56 stands in the study area. Parameter estimates for the predictive equation were obtained using least-squares linear regression.

This book was released on 2010-10 with total page 282 pages. Available in PDF, EPUB and Kindle. Book excerpt: Explores the relationships between forest management activities and timber quality. Sessions were organized to explore models and simulation methodologies that contribute to an understanding of tree development over time and the ways that management and harvesting activities can influence the quality of timber products recovered from those trees. Five keynote addresses, 29 plenary presentations, and 16 poster presentations covered the full breadth of forest growth and timber quality issues related to forest management. These proceedings comprise 19 papers based on presentations and posters, plus 28 abstracts for presentations. Also includes abstracts and slides from the presentations prepared by three keynote speakers. Illustrations.

Download or read book Estimation of Total Height Growth and Mortality of Forest Trees in Missouri written by James Lootens and published by . This book was released on 2005 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: A model for predicting total tree height as a function of tree diameter was calibrated for twelve tree species common to the Missouri Ozarks. Model coefficients were derived from nearly 10,000 observed trees. The calibrated model did a good job predicting the mean height-diameter trend for each species (pseudo-R2 values ranged from 0.56 to 0.88), but for a given tree diameter observed tree heights were highly variable. In addition, an evaluation of the Central States variant of the Forest Vegetation Simulator (CS-FVS), a distance-independent, single-tree growth model was performed on forest inventory data from a managed, uneven-aged forest in the Missouri Ozark Highlands. Simulations were run for ten and forty year time periods, and evaluated diameter growth, number of trees per acre, and basal area. The model was also evaluated with and without providing diameter increment calibration information. CS-FVS performed reasonably well in predicting diameter growth, as compared to other evaluations of similar models. The model consistently overpredicted the number of trees per acre and basal area for all simulations. The model underpredicted mortality, especially for black and scarlet oak. Diameter increment information improved prediction the most for diameter growth and basal area estimations.

Book excerpt: Excerpt from A Method for Estimating the Preharvest Potential for Seedling Height Growth on Cutover Forest Land in Southwestern Oregon This regression can be used to predict the height of unbrowsed 5-year-old seed lings on cable-yarded, broadcast-burned clearcuts in southwestern Oregon. It should be most helpful, however, when it is used to estimate preharvest growth potential on cutover land where site quality has been affected by logging or by site preparation treatments. Only measurements of stumps are required, and those measurements reflect the undisturbed conditions present when the stumps were saplings with diameters of 10 centimeters in).
