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.
