Abstract An increasing number of forest plantations established 20 or more years ago are reaching the age at which thinnings should be initiated if the maximum production of high-grade lumber is to be obtained. This report of the first commercial thinning of planted white pine stands in the Eli Whitney Forest, near New Haven, Conn., should interest persons entrusted with the care of plantations of similar age elsewhere.
