Hi,
this morning I had a chance to measure the biggest black birch at UMass,
and it was 105 inches in circumference. That puts it in the range of the
black birch at Vanderbilt Estates

Vanderbilt
Other species include:
Species Height Circumference
Black birch 105.3 8.8

I've been looking at ENTS site and haven't found much about black birch
... I'm hoping that if people come up with criteria for a list of
hardwoods that are big for their species within a given range, that one
of the trees to be considered is black birch (not just the really big
trees like red oaks and white pines)

Elisa,

If those measurements hold up, the tree will become the new state champion. I'm assuming that you did the measuring. If so, did you use laser and clinometer and the sine method? Black birch are extremely easy to over-measure on height using clinometer and tape measure only. If you want someone to check the height calculation, I'd be most pleased to drop by UMASS, meet you there, and provide a second measurement.

Bob,
I must have written unclearly - we only measured the circumference - 105
inches. The height data was from a tree on the Vanderbilt Estate that
somone from ENTS measured several years ago -I'd been on the ENTS site
looking for data on black birches and was pleased to see the UMass one
seems comparable in circumference. I'd never attempt to measure the
height but I'd be delighted to lead anyone who is good with height
measurements (or anyone else interested in large trees in unexpected
places) to it.
