Invasive Plant Atlas of the U.S.

Invasive Plant Atlas of the United States - A collaborative project between the National Park Service, the University of Georgia Center for Invasive Species and Ecosystem Health, the Invasive Plant Atlas of New England and the Lady Bird Johnson Wildflower Center. The purpose of the Atlas is to assist users with identification, early detection, prevention, and management of invasive plants, with an emphasis on primarily non-native plants.

We provide resources on the following invasive plants:

Black dog-strangling vine, black swallowwort (Cynanchum louiseae)
