Invasive species, including non-native plants and animals, pose significant threats to biodiversity, costing the U.S. nearly $140 billion a year in damages and control efforts. This comprehensive overview addresses basic terminology related to invasive species and their impact on ecosystems, highlighting the decline of native species due to competition and predation. With real examples from ecosystems like Chesapeake Bay, the report emphasizes the need for state-specific laws and regulations to combat this rising problem, urging public awareness and involvement to protect natural habitats.

Basic Terminology • Invasive Species - alien, non-native animals and plants introduced into ecosystems • Non-Native – not from the place or environment in which a person was born or a thing came into being • Biodiversity - diversity among and within plant and animal species in an environment
Chesapeake Bay, Maryland The mute swan (upper right) is extremely antagonistic. Though a gorgeous symbol of love, this swan can “drive away native birds and devour underwater grasses.” Hydrilla (lower right) is an invasive plant. It reduces the diversity in the area by dominating space causing other plants to die out. As a result, the marine animals the feed off of the now extinct plants also die out.
Economic issues Nearly 140 billion dollars is spent on damage and control costs for invasive species annually in the United States. After all, we all know money doesn’t grow on trees…
Biodiversity & extinction Non-native species are a major threat to biodiversity. They may consume eggs of a species or a species itself. Invasive species also cause greater competition for resources.“Of all 1,880 imperiled species in the US, 49% endangered because of introduced species alone or because of their impact combined with other forces.”
Laws, Fines, and Bans In the United States, every state has different laws and bans. In Florida for instance, many animals and plants are banned. Some include the Australian Pine, Hydrilla, Japanese Climbing Fern, Fire Ant(near right), Zebra Muscles(far bottom right), and the Great Toad (far top right). If you are to try to import any of the banned species and are caught, a juicy fine and maybe a little jail time is in your near future.
How About Our Golden State? In California, the California Exotic Animal Laws have been in place since 1933. That set of laws along with the California Code of Registrations Title 148671 covers the transport of exotic animals.
