Ulmus Americana, commonly known as the American elm, is a large deciduous tree native to North America. It can grow up to 100 feet tall and is characterized by its broad, vase-like shape and serrated leaves. The tree is often found in urban areas and along streets due to its tolerance for pollution and adaptability to various soil types. Historically, the American elm was a popular shade tree, valued for its beauty and strength. However, it has faced significant decline due to Dutch elm disease, a fungal infection spread by beetles. Conservation efforts are ongoing to restore healthy populations of this iconic tree.
