I understand that the chestnut blight hits most American chestnuts which are
planted in relatively wet areas. Therefore look for blight-resistant trees on
slopes. At one time these magnificent trees were prevalent over much of the
eastern US, attaining profound girth. The wood is generally resistant to most
fungal degraders, like Western red cedar is. Unfortunately the chestnut blight
was brought in on non-native trees, and spread rampantly.
In Oregon, some American Chestnuts still apparently survive, possibly the
result of a judge who imported them from the east coast to near Corbett,
Oregon (along the Columbia Gorge). Although these trees are supposedly some of
the largest remaining American chestnuts, identification is nearly impossible.
It seems that American chestnuts interbreed easily with many other chestnut
species, many of which were also brought into Multnomah County, Oregon as
ornamental trees. And yet...the chestnuts I've seen near Corbett have already
reached 4-5 feet diameter.
I wish you well in your search. Please be sure to post to ng if you find a
source: I'm interested in cultivation as well. I have a few acres of rather
steep, well-drained soils where American chestnut should do fine. I'll even
settle for non-infected certified Amerian chestnut seed, if I could ever find
out how to germinate them. (hint, hint)
