Book Synopsis Growth Intercept, Years-to-breast-height, and Juvenile Height Growth Models for Ponderosa Pine by : Gordon Donald Nigh
Download or read book Growth Intercept, Years-to-breast-height, and Juvenile Height Growth Models for Ponderosa Pine written by Gordon Donald Nigh and published by . 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.

Book Synopsis Extending Southwest Oregon's Douglas-fir Dominant Height Growth Equation to Older Ages by : David W. Hann
Download or read book Extending Southwest Oregon's Douglas-fir Dominant Height Growth Equation to Older Ages written by David W. Hann and published by . This book was released on 1998 with total page 24 pages. Available in PDF, EPUB and Kindle. Book excerpt: Hann and Scrivani (1987) developed dominant height growth equations for Douglas- fir in southwest Oregon using stem analysis data sets with an upper age of approximately 125 years at breast height. The objective of this study was to determine whether these equations could be extrapolated for ages of 250 years or more. Data for the evaluation came from stem analysis of 60 dominant trees located in 30 "older" stands. Intensive data screening indicated that 53 of these trees exhibited signs of reduced height growth during their first 100 years of development due to competition from non-tree vegetation, hardwood tree species, and possibly other conifers in non-even-aged stands. Analysis of the remaining seven site-quality trees indicated that the existing dominant height growth equation for Douglas-fir could be extrapolated to breast height ages of up to 245 years without loss of accuracy or precision.

Book Synopsis Juvenile Height Models for Lodgepole Pine and Interior Spruce by : Gordon Donald Nigh
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.

Book Synopsis Development of Tree Height and Diameter Growth Equations for Mid-Willamette Valley Douglas-fir by : Martin W. Ritchie
Download or read book Development of Tree Height and Diameter Growth Equations for Mid-Willamette Valley Douglas-fir written by Martin W. Ritchie and published by . This book was released on 1985 with total page 166 pages. Available in PDF, EPUB and Kindle. Book excerpt: Equations for predicting height growth, basal area growth and diameter inside bark are presented for Douglas-fir. Basal area growth equations for grand fir are also presented. The growth models were developed for use in an individual tree/distance independent growth simulator. Various model forms and measures of competitive stress were compared in both the height and basal area growth models. The height growth equation is a function of crown ratio and height divided by dominant stand height. Basal area growth is a function of tree diameter, crown ratio, crown competition at the plot level, stand basal area and either site index or predicted height growth. The diameter inside bark equation, used in backdating tree diameters, is a nonlinear function of diameter outside bark.
