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. The following categories have been created in order to make it easier to locate the invasive species in which you are interested.
