    Description

    Second-growth white pine age-height data a A base-ageinvariant polymorphic site index equation was used to model the white pine (Pinus strobus L.) site-quality data provided by Frothingham (1914). These data are the accepted standard used by the Southern Forest Inventory and Analysis unit of the U.S. Department of Agriculture, Forest Service. An all possible growth intervals data structure was used, and autocorrelation parameters were incorporated into the site index model. It has recently been been shown that these measures arc necessary to obtain unbiased, efficient parameter estimates. The model is invertible, hence site index can be explicitly determined without the need for a numerical evaluation procedure. The site index model can be solved to provide an equation for any base age, hence it is applicable regardless of the choice of rotation age. Site index curves are graphed for base ages 25 and 50 years, and example calculations are provided.
