The Parks Commission is seeking volunteers to help remove a stand of Tree-of-Heaven (Ailanthus altissima) at Peoples Park on October 19 at 8am. Closed-toe shoes, loppers, and gloves will be required.
This species of fast-growing tree is highly invasive and rapidly spreads through high seed production and root sprouting. It is also the host plant of the invasive Spotted lanternfly (Lycorma delicatula), which has recently been found in Michigan.
Wondering if you might have a Tree-of-heaven in your yard? Mature trees resemble Black Walnut trees but have noticeable differences: Tree-of-heaven has smooth bark and a single terminal leaflet, while most black walnut trees have dark, rigid bark and two leaflets at the tip of their leaves. If in doubt, give leaves a smell test. Tree-of-heaven, even young trees, tend to smell like rancid peanut butter.
