Hi
All,
I have finally put together Eastern OLDLIST v 1.0, a database
for maximum
tree ages for species found in eastern North America as
documented through
dendrochronological investigations. The database was triggered
into action
by a discussion on the tree ring forum nearly one year ago.
Eastern OLDLIST is a 'franchise' of Peter Brown's OLDLIST.
Currently it
has over 40 species and several species pages showing the
geographical
distribution of old trees for certain species. I anticipate
more numbers to
trickle in over the next few months. In fact, within a couple
of hours of
announcing this list to the tree-ring forum late this
afternoon, I received
two emails with new ages, one of which pushes the max black
oak age up
another 8 yrs. I expect the documented age of black oak to
increase rapidly
in the next few years. At any rate, a search through the
International Tree
Ring Data Bank is not yet complete. So, these pages will
continue to evolve
and grow through time. Please considering submitting ages
and pictures for old trees and forests.

I think we are a long way from getting really max ages on
many species,
esp.
of those currently under 200 yrs. Of the 350 or so species in
eastern N.A., few have been studied sufficiently well enough
to know max
age. Bigtooth aspen and Aesculus flava are two examples. Pages
will grow as
submissions grow, esp. for species like cucumbertree.
Have a good weekend,
Neil
