How do invasive species get here?

Invasive species have been introduced through many avenues. Intentional introductions have been made for agricultural crops, landscaping, ornamental plants, and for the pet trade. Once introduced, a few species have escaped cultivation  or domestication and have established viable populations in the wild. Some of these populations not only survive, but thrive and increase.

Accidental introductions include contaminated freight such as plants, wood, or food that contain propagules of invasive species,  such as seeds, eggs, spores, or other biological material capable …

How do invasive species cause harm?

Invasive species can cause harm in so many different ways that it isn’t practical to cover them all here. So, below is just a sample to give you an idea of how pervasive this problem is. Many of these changes are things you can see happening around you.

When a non-native species is introduced into a new environment it is freed from the natural predators, parasites, or competitors from its native habitat. This gives an advantage to non-native species competing …

Aquatic (Water-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 …
