ULMACEAE - - Elm Family

Ulmus americana Linnaeus — American Elm

Habitat:

Swamps, bottomland forests, moist slopes, especially on relatively or strongly nutrient-rich substrates. Ascomycetous fungi, Ophiostoma ulmi and O. novo-ulmi, are the cause of the Dutch Elm disease. In our area, the effects of the disease appear to have been variable, with less impact southwards and in natural populations (as compared to suburban or urban plantings).
