From:
Today I drove a beautiful street in Fargo, ND that is lined with
100+ year old American Elms. It made the news here that they
actually had to cut a few down due to Dutch Elm Disease!
I will post the chestnut pictures when I get back home. I wish that
I could have gotten 4th of July pictures of the tree. The owner says
that the flowers are so dense and bright that they are visible from
across the bay on boat. The squirrels get any nuts too fast for
people to get any. I measured the tree height with the standard ENTS
laser-clinometer sine method. All the trees this close to the Lake
Superior shoreline are of similar heights. It is only a few blocks
from the lake.
The grove with the state champion tree was treated with the
hypovirus with some initial success but the blight is still
spreading there according to the last information that I have. I had
heard that the stand was already rich in other native fungi that
might somehow be slowing the spread of the blight in the grove. They
are in an area where the prairie-forest tension zone intersects with
a section of the driftless area (never glaciated.) All of this may
come into play as an environment not quite ideal for the blight, but
it survives degraded nonetheless.
