American Elm, or White Elm, is one of the most beautiful, graceful, and best known forest trees in New York State and grows to be one of the largest trees in the state and may live for up to 300 years. Cork Elm, or Rock Elm is most often found at dry sites with shallow soils over limestone bedrock, often on ridges or exposed ledges. It has the hardest and heaviest wood of the elm species, and is desirable for use in furniture, tools, and fence posts. American Elm has nearly disappeared from our parks and streets because of the lethal Dutch Elm disease. The elm zigzag saw fly maybe a future threat.
