American Elm

A Stately Survivor
The American Elm is known for its towering height and wide branches that create a "cathedral ceiling" effect.
This mature specimen is the last remaining tree from an allιe planted in the 1930s. Unfortunately, during that era, Dutch elm disease, a fungal disease from Europe, caused elms to decline. Before the onset of this disease, these trees had lifespans of hundreds of years. Ongoing efforts are focused on restoring and protecting this iconic species.
Historic Tree Preservation
To care for this hundred-year-old beauty, we focus on maintaining its health above and below ground. The trunk has a large scar from a windstorm in 1998, and a significant limb fell in 2021, but it is still going strong.
