Tree of Heaven (Ailanthus altissima) is a deciduous tree native to northeast and central China and Taiwan.

Annual Growth Rate: 3-7 ft.

Location (Throughout Park):

• Forest & grassland edge
• Disturbed soils
• Roadsides and forest edges

Impacts:

• Aggressively sprouts new saplings when cut, dominating the surrounding area up to fifty feet away from parent tree.
• Secretes chemicals which prevent growth and establishment of native species.
• Favorite host plant of the Spotted Lanternfly (courtesy of PennState Extension).

Management:

Park biologists are monitoring existing locations and are addressing new growth areas as they are detected. Cutting the Tree of Heaven causes aggressive sprouting, so early identification and herbicide application by park biologists is the most effective method for managing growth and spread of this invasive species.

What Can You Do?

As a devoted visitor to Gettysburg National Military Park, you can see the direct impact the Tree of Heaven is having on your park. During the warm weather months, we host a series of Volunteer Work Days. Sign up for one or all of these to lend a hand! You have the opportunity to aid our staff to combat this invading species and perhaps slow or halt their march across our fields, our hills, our stone walls, our fences, or even around our monuments.

• Report any sightings of Tree of Heaven.
