Abstract
The American elm, Ulmus americana L., has proven itself to be particularly well adapted to urban environments. Unfortunately, Dutch elm disease, caused by the fungus Ceratocystis ulmi (Buism.) C. Moreau, has limited use of this species. The ‘Pioneer’ hybrid elm is a product of a USDA program to develop disease resistant elm clones which can be planted as substitutes for American elm.
