Download or read book A Growth Intercept Model for Coastal Douglas fir written by Gordon Donald Nigh and published by University of British Columbia Press. This book was released on 1997 with total page 32 pages. Available in PDF, EPUB and Kindle. Book excerpt: Growth intercept models can compute site index (which measures the capacity of an area of land to grow trees of a given species) from early average height growth of trees. This guide describes a growth intercept model for coastal Douglas fir in British Columbia. The model was developed from a study of 48 analysis plots in which three trees in each plot were selected for intensive sampling, reconstruction of growth history, and calculation of site index and growth intercept. The resulting model consists of 50 functions. Four refinements to the growth intercept modelling technique are introduced, which improve the functional form of the model and improve the data collection and analysis procedures.

This book was released on 2002 with total page 16 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report describes features of three models developed for estimating site index & height growth of ponderosa pine. The models are based on data from 80 ponderosa pine stem analysis plots established throughout the range of this species in British Columbia. The first model is used to calculate the number of years that a tree takes to reach breast height. The second model calculates the average annual height growth, adjusted for age. The final model is for calculating juvenile height.

Download or read book Western Redcedar Site Index Models for the Interior of British Columbia written by Gordon Donald Nigh and published by . This book was released on 2000 with total page 36 pages. Available in PDF, EPUB and Kindle. Book excerpt: This paper develops models to predict top height, site index, and years to breast height for western redcedar, Thuja plicata, on interior British Columbia sites. Stem analysis & ecological data were collected from 46 plots in the interior cedar-hemlock and interior Douglas-fir biogeoclimatic zones. Four site trees were stem analyzed from each plot. These data were converted into top height-breast height age, growth intercept, years to breast height, and site index data. A site index, growth intercept, and years to breast height model were then fit to the data.

Download or read book Juvenile Height Models for Lodgepole Pine and Interior Spruce written by Gordon Donald Nigh and published by University of British Columbia Press. This book was released on 2004 with total page 28 pages. Available in PDF, EPUB and Kindle. Book excerpt: Juvenile height models have been developed with data collected from a small area of British Columbia for lodgepole pine and interior spruce. The purpose of the project described in this report is to validate these models with data from six biogeoclimatic zones where lodgepole pine & interior spruce commonly occur. Trees were sampled from plots in each zone and annual height was measured directly from pith nodes. A rigorous validation procedure was applied to validate the models for the province as a whole and on a zonal basis. A slight bias revealed in the models led to refitting of new models to the new data. A small validation of the new model for lodgepole pine demonstrates whether it is adequate for use in the interior Douglas fir zone.

Download or read book Modeling Forest Trees and Stands written by Harold E. Burkhart and published by Springer Science & Business Media. This book was released on 2012-04-27 with total page 463 pages. Available in PDF, EPUB and Kindle. Book excerpt: Drawing upon a wealth of past research and results, this book provides a comprehensive summary of state-of-the-art methods for empirical modeling of forest trees and stands. It opens by describing methods for quantifying individual trees, progresses to a thorough coverage of whole-stand, size-class and individual-tree approaches for modeling forest stand dynamics, growth and yield, moves on to methods for incorporating response to silvicultural treatments and wood quality characteristics in forest growth and yield models, and concludes with a discussion on evaluating and implementing growth and yield models. Ideal for use in graduate-level forestry courses, this book also provides ready access to a plethora of reference material for researchers working in growth and yield modeling.
