Site Index Curves for Forest Tree Species in the Eastern United States

摘要

The goal of the paper is to inventory and summarize the site index curves available for forest tree species in the eastern United States. Accordingly, the paper is an updated summary that includes 127 site index curves presently considered to be useful for managing eastern hardwood and conifer forest species. Additional site index curves not included among the redrafted and formulated curves of the report are listed in Appendix I. Forest site quality is an estimate of the capacity of forest land to grow trees, thus forest site quality corresponds to land capability for growing various agricultural crops.
