Tree diameter growth where = observed and predicted q-year diameter growth (cm) for tree i, respectively, = mean -year q diameter growth, ns = = total number of surviving trees in the data, and the sum includes values of i from 1 to ns. Fit index is analogous to R 2 in linear regression, with a maximum value of 1 for perfect prediction. The Forest Vegetation Simulator (FVS, Wykoff et al. ; Dixon ) is a distance-independent, individual-tree forest growth model commonly used in the United States to support forest management decisions. Projections are typically made at the stand level, but FVS has the ability to expand the spatial scope to much larger management : Diane Kiernan.
Among various measurements of tree growth, diameter of tree stem has been most widely monitored because of the easiness and accuracy of the measurement compared to tree height. There are several theoretical models to express stem diameter growth of individual tree. One of the simplest is a model based on the metabolic scaling theory. Enquist et by: 2.

The United States national inventory program measures a subset of tree heights in each plot in the Pacific Northwest. Unmeasured tree heights are predicted by adding the difference between modeled tree heights at two measurements to the height observed at the first measurement. This study compared different approaches for directly modeling year height increment of red Author: Hyeyoung Woo, Bianca N. I. Eskelson, Vicente J. Monleon. We examined four individual tree models in Europe: BWIN, Moses, Silva and Prognaus. We simulated growth of open-grown trees and on research plots for 15 or 30 years. Height:diameter ratios were correctly predicted by all four models. Height:diameter ratios were within the bounds of open grown trees and dense stands. They decreased with age and Cited by:

An individual-tree diameter increment model is developed for fir plantations using a multi-level linear mixed effect model approach.

Due to its geographic location, topology, and history of management, the forests of the Adirondacks Region of New York are unique and complex. However, only a relatively limited number of growth and yield models have been developed and/or can be reasonably extended to this region currently.
Cited by: 8. Various methods for predicting annual tree height increment (∆ht) and height-to-crown base increment (∆hcb) were developed and evaluated using remeasured data from permanent sample plots compiled across the Acadian Forest of northeastern North America.
Across these plots, 25 species were represented upon which total height (ht) measurements Cited by: We should consider the effect of thinning on tree growth when predicting long-term tree growth. Several studies created diameter growth models under different thinning intensities [12,20,21].For example, Uzoh and Oliver  designed a single diameter growth model using the site density index (SDI) and the basal area of larger trees than the subject tree (BAL).
Model 2 was also found to be accurate in simulating diameter and height growth in individual eucalyptus trees, revealing greater consistency between the statistics and biological reality and thus providing the most accurate and best fitting model for diameter and height growth.
In Brazil, individual tree growth models are still rarely used to. Project Methods This project would compile regional growth and yield datasets available from the University of Maine Cooperative Forestry Research Unit, United States Forest Service, and several Canadian governmental agencies.
The data would be used to refit individual tree diameter and height growth as well as mortality equations. Growth and mortality modifiers.
