Pitch pines are a keystone species that determine the composition and structure of unique coastal rocky ledge plant communities at many sites on Mount Desert Island. Mike Day, associate research professor of tree physiology and physiological ecology with the School of Forest Resources at the University of Maine, has been studying these trees for many years. He will share his thoughts and perspectives regarding this fascinating plant and the plant communities it supports in a talk on Sept. 14.
This talk will be held in the restored barn at Garland Farm, off Route 3 in Bar Harbor. It is being hosted by the Beatrix Farrand Society, which honors the work of one of the most renowned landscape architects in the United States. The cost of the program is $10 for members of the Beatrix Farrand Society and $20 for nonmembers. For more information, call 581-2937 or visit www.beatrixfarrandsociety.org.
