Many exotic species pose no threat, but some are invasive and grow out of control — displacing native plants which provide food and shelter for an assortment of native wildlife. Unfortunately, it is not always possible to predict if or when a species will become a pest plant (for example, Japanese honeysuckle was planted as an ornamental for 80 years before it escaped cultivation!), but a red flag should run up at any non-native with fleshy fruits dispersed by birds.
NameThatPlant.net attempts to make the viewer aware of species which have been found to cause problems in natural areas of the Southeast by labeling that plant as INVASIVE. Some of these plants are a greater threat than others (for more information, explore the links below) but we recommend that they not be planted, expecially near a natural area.
Invasive.org, Center for Invasive Species and Ecosystem Health
Invasive.org focuses on Invasive and Exotic Species of North America, that is, any species, including its seeds, eggs, spores, or other biological material capable of propagating that species, that is not native to that ecosystem; and whose introduction does or is likely to cause economic or environmental harm or harm to human health. Here you can find species profiles, images, publications, videos, how to and FAQs.
EDDMapS — Early Detection and Distribution Mapping System — is several things.
It is a web-based mapping system for documenting invasive species and pest distribution that is fast, easy to use, and doesn't require Geographic Information Systems experience,
and it is a website that anyone can use to see up-to-date county-level maps tracking the spread of invasives throughout the country.
Plant Invaders of Mid-Atlantic Natural Areas
This book includes information and control guidance on 80 invasive species. A section called “Plants to Watch” includes a number of species that may not be widespread but are increasingly catching the attention of ecologists,
land managers and others as being invasive in natural habitats. Native plant alternatives have been consolidated in a separate

Plant Conservation Alliance: Weeds Gone Wild
A web-based project of the Plant Conservation Alliance's Alien Plant Working Group that provides information for the general public, land managers, researchers, and others on the serious threat and impacts of invasive alien (exotic, non-native) plants to the native flora, fauna, and natural ecosystems of the United States.

Weed of the Week
Access to invasives plant lists and over 100 Weed of the Week factsheets, which include plant description, habitat and distribution information, ecological impacts, and control and management information. Prepared by the USDA Forest Service (Northeastern Area).
Invasive Plant Atlas
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. The focus is on non-native invasive plant species impacting natural areas, excluding agricultural and other heavily developed and managed lands. Four main components are species information, images, distribution maps, and early detection reporting procedures.
Nonnative Invasive Plants of Southern Forests — USDA Forest Service
This book provides information on accurate identification and effective control of the 33 nonnative plants and groups that are currently invading the forests of the 13 Southern States, showing both growing and dormant season traits. It lists other nonnative plants of growing concern, control strategies, and selective herbicide application procedures.
