Book excerpt: Excerpt from How Damage to Balsam Fir Develops After a Spruce Budworm Epidemic There is a lag between the initial defoliation of a fir tree and the first reduction in diameter growth. Another lag of at least 3 years occurs between the time of crown recovery after the epidemic, and a response to this recovery in terms of diameter growth. These lags are thought to be related to continued photosynthesis in the old needles. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.
