Invasive – Ailanthus altissima: Targeting the Tree of Heaven

Tree of Heaven (Ailanthus altissima) is an aggressive tree species that continues to colonize vulnerable and disturbed areas in NH. The species can spread very quickly, outcompeting native plants and forming dense thickets, which degrades overall ecosystem function. Tree of Heaven also serves as the primary host for the adult Spotted Lantern Fly, an invasive plant hopper from China, India, and Vietnam. The immature lantern flies can cause significant damage to apples, peaches, and grapes as well as birch, maple, and black walnut. Join industry specialists to learn more about both of these important invasive species. Topics will include basic identification, ecology, control strategies for various settings, and how to cut and remove Tree of Heaven after treatment.

This class is co-sponsored by UNH Cooperative Extension, NH Department of Agriculture, Markets & Food, and NH Timberland Owners Association. The objective of this class is to provide information to a targeted audience with the ability to contain and mitigate this species before it causes more harm in the state of New Hampshire. Attendees will be encouraged to share information with others in their organization, town, or professional groups.
