InfoINFORMATION Elm trees originated in central Asia and flourished in North America. Beginning in the 1950's, Dutch elm disease cut the Elm population in half. Despite the high disease pressure, the American Elm on the UA Fort Smith campus is estimated at between 150 and 200 years of age. It is however starting to show signs of stress and old age with thinning branches. To help prolong the inevitable, the grounds staff routinely mulches under the tree to minimize grass competition and prunes to remove parasitic mistletoe.
