Invasive species are plants and animals that originally come from another area of the world, and can easy become established in our ecosystems.  Since they lack natural controls and are able to grow and spread quickly, they can rapidly crowd out native species. Infamous aquatic invasive species include zebra mussels, the sea lamprey, round gobies, eurasion milfoil, phragmites, and the asian carp.  Some terrestrial species are honeysuckle, common buckthorn, garlic mustard, dame’s rocket, and autumn olive.

There is a wealth of information on invasive species on the internet; here are some useful links.
