Site index (SI) is a measurement commonly used by foresters to describe the productivity of a site. To calculate SI, first identify dominant and codominant trees representative of the forest site. The total height and ages of these trees are needed to calculate SI. For our purposes, measurement of one dominant and one codominant tree of a similar species is adequate.
