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)
Aquatic (water-dwelling) invasive species are non-native plants, animals, and other organisms that have evolved to live primarily in water (aquatic habitats) rather than on land (terrestrial habitats). Aquatic habitats are habitats that are covered with water all or part of every year. From oceans to bogs, many types of aquatic habitats exist.
Aquatic invasive plants include algae, floating plants, submersed plants, and emergent plants. Aquatic invasive animals include insects, fish, reptiles, mollusks, crustaceans, and amphibians. Other aquatic invasive organisms include pathogens (disease-causing organisms), such as molds, fungi, bacteria, and viruses. (Source - eXtension: Aquatic (Water-Dwelling) Invasive Species)
