<a href=" --Apple-Mail-141-915338774 Content-Type: text/plain; charset=US-ASCII; format=flowed; delsp=yes Content-Transfer-Encoding: 7bit Hi folks, There's a paper by Colin Laroque from the Mount Allison Dendrochronology Lab on what is believed to have been the oldest red oak (Quercus rubra) on Prince Edward Island which was dated at 126 years old. http://www.mta.ca/madlab/2006-01.pdf The "Oldlist" database of ancient trees cites Orwig et al. (2001) as having found found the oldest red oak (Quercus rubra) ever recorded at 326 years of age. http://www.rmtrr.org/oldlist.htm There's a list of old red oaks (Quercus rubra) ranging between 326 and 134 years from various parts of the United States which is part of the eastern Oldlist: http://www.ldeo.columbia.edu/~adk/oldlisteast/Spp/QURU.html This includes a photograph of Dr. David Orwig standing next to the oldest known living Quercus rubra (326 yrs) on Wachusett Mountain just outside of Boston, Massachusetts. This was taken in 2006 so, if the tree is still standing, it is presumably now 332 years old. There's also an article in Science Daily from 2000 on what is believed to be the oldest recorded hardwood east of the Mississippi, a white oak (Quercus alba) that was felled in Ohio a storm in 1998, which was 373 years old. http://www.sciencedaily.com/releases/2000/11/001103071631.htm Based on the above, there's really no chance that a red oak in Nova Scotia would be over 400 years old. Even a tree half that age would be an extremely old one for this region. Cheers!
