Height models for juvenile even aged mixed-species stands were developed for locations near Nelson, British Columbia. Separate models were developed for each conifer species found, as well as for paper birch (Betula papyrifera). The objectives were to develop models for: 1) the number of years to reach breast height; 2) height achieved at a given age above breast height (height yield); 3.

Growth intercept models which relate the early average height growth of trees to site index, have been shown to provide reasonable site index estimates for young stands [35,36,46,59]. Although the growth intercept model has proven to provide significant information on growth and yield of conifers, it still represents an early estimate of the.

Models to predict height SDS at 5 y were developed using data for 1 yr (Model 1) and 2 yrs (Model 2). The data of (63%) children were available: SGA: n = , AGA: n =   Highlights A modified version of the 3-PG model was used to predict growth of Pinus taeda plantations. The model was calibrated with data from one highly productive stand. Seven fast and slow growing plantations were used to validate model predictions. 3-PG produced accurate predictions of stem biomass, diameter and volume growth. It was less accurate in predicting stand density.   Height distribution of five cohorts of year-old Swiss conscripts from / to / (representing ~90% of the total census population).
