Formerly abundant, in most of its former range, only very-young, short or treated trees can be found, due to infestation by
Dutch elm disease (DED) Ophiostoma ulmi and related
(prevention and treatment [archived]).
This author has seen two beautiful majestic mature elms, apparently spared from DED by geographic isolation. And some adolescent trees, too young to be attacked by the disease. And read about treatments and
blight-resistant hybrid cultivars.
But these actions seem pretty pathetic, compared to the scale of destruction.
