Ulmus americana

American elm

Botanical description: Ulmus americana was once the most common street tree in cities, due to its overall elegant vase-shape form, rapid growth and its tolerance of pollutants and drought. American elm has suffered a serious decline since the arrival of Dutch elm disease in the 1930s, slowly spreading across North America. However, Ulmus americana can still be found and often seeds into tough, urban habitats along with newcomers such as Siberian elm. American elm offers refuge, habitat and food to over 100 different species of insects, birds and mammals. The elm feeds pollinators through its flowers, caterpillars and butterflies feed on the foliage and several moths, leafhoppers and beetles seek the tree as host. Over 20 different kind of birds feed on the seed and buds of the tree while several consider the American elm as ideal for nests. Several species of mammals forage the seeds while rabbits and white-tailed deer browse twigs and foliage. Ulmus americana also supports the infamous beaver’s gnawing habits, as both species prefer moist bottom lands
