Site Index
Site index
A means of evaluating a forest's potential to produce trees for timber. Site refers to a defined area, including all of its environmental features, that supports or is capable of supporting a stand of trees. Site index is an indicator used to predict timber yield based on the height of dominant and co-dominant trees in a stand at a given index age, usually 50 or 100 years. Normally, site index curves are prepared by graphically plotting projected tree height as a function of age.
