cedars in Wisconsin

I get the magazine Wisconsin Natural Resources (published by the
Wisconsin Department of Natural Resources), and this month's
(December 2005) has an article written by Kathryn Kahler titled
"Vertically Inclined" about the ancient northern
eastern redcedars found primarily on the Niagra Escarpment that
topic of discussion on the ENTS list not that long ago (I
Frelich had initiated that conversation).
In her article, she interviewed Jeffrey Nekola of the University
Wisconsin-Green Bay, who had been aging some of these cedars
Larson (botanist/dendrochronologist at University of Guelph who
studied similar cliff ecosystems in Canada). The ages of some of
trees in the land of beer and cheese were remarkable! According
quote of Nekola, they dated an eastern redcedar near Green Bay
about 1,200 years old, and several northern white-cedars 500 to
years old in other parts of the area.
These cliffside communities are remarkably unique in their
diversity, by providing habitat for rare species, and also by
ancient if diminutive trees. Cool!!

Ancient cedars in Wisconsin

Growing up in northern Wisconsin, I never thought much about the
northern white-cedars that we would see along the escarpments
at places like Copper Falls State Park or in the UP of Michigan,
I'm curious as to how ancient these cedars may be...
I do remember counting the rings of some northern white-cedar
a swamp near my parent's house, and being impressed that these
non-descript individuals were 150+ years old. I suspect there
are a lot
more old trees like this across much of the upper midwest,
from logging by their small stature, poor access, and limited

Thanks for the information on these old cedars. We are
getting a far
number of post dealing with old trees. I might even need
to make a separate
section on the website for dendrochronology. The post by
about "cedar complexes" formed by fallen trees
whose living branches in turn
grow into new trees. The entire subject of these cedar
groves fascinates me.
The previous post on the subject is posted at:
Some earlier discussion of white cedar are also posted

I visited a fairly young cedar swamp at the Michigan
Visitors Center this summer myself, but want to visit
these examples on
the Door Peninsula and the Niagara Dolomite Escarpment.
