Terrestrial Invasives

Terrestrial (land-dwelling) Invasive Species are non-native plants, animals and other organisms that evolved to live on the land rather than in aquatic (water) habitats. Terrestrial habitats are simply habitats that are primarily focused on land. From forests to prairies there are many different types of terrestrial habitats.

Invasive terrestrial species include plants, animals and other organisms. Terrestrial invasive plants include trees, shrubs, vines, grasses and herbaceous plants. Terrestrial invasive animals include insects, mammals, reptiles, arachnids, birds and nematodes. Other terrestrial invasive organisms include pathogens (disease causing organisms) such as molds, fungus, bacteria and viruses. (Source - eXtension.org: Terrestrial (land-dwelling) invasive species)

Species Information Disclaimer

NISIC provides general information about species considered to be invasive and our information does not have any regulatory implications. There are more than 6,500 invasive species established across the United States. The large numbers of invasive species prevent us from maintaining detailed information on all invasive species. In addition, determining the invasiveness of a species depends on a number of local factors, including type of habitat. The species profiles included on NISIC's site are intended to be an educational resource and should not be considered to be an official list of invasive species by the U.S. Department of Agriculture.
