Exotic species can have severe negative effects on vulnerable freshwater communities, particularly lakes and isolated stream systems. As for accidental introductions, human activities serve as the means for the species to be transported from one geographical location to another. Science News 139 (May 4, 1991): 282–84. It is not always considered a nuisance or invasive. However, researchers disagree as to the extent of environmental damage it causes. Invading species can cause complex changes within the structure and function of their new ecosystem. Invasive species. One of the common reasons for introducing a species to a non-native location is to serve as a biological control agent of certain species, particularly those that produce harm. But it has suffered the highest rate of extinctions of any area of the United States and one of the highest rates anywhere in the world, with hundreds and possibly thousands of unique species already extinct.

Many of the small lakes near the Great Lakes are not connected to the Great Lakes by waterways, but they still have zebra mussels. Some notable examples are kudzu (Pueraria lobata ), the zebra mussel (Dreissena polymorpha ), Africanized bees Apis mellifera scutellata ), and Eurasian milfoil (Myriophyllum spicatum ). It is introduced into an area where it does not occur naturally. Such solutions, and the time and money to develop them, are usually elusive and politically controversial, so in many cases effective control methods remain unavailable. Richmond, Elliot "Exotic Species System of Registries | US EPA. America's Least Wanted: Alien Species Invasions of U. S. Ecosystems. It is not always considered a nuisance or invasive. Area industries spend hundreds of millions of dollars annually unclogging pipes and equipment, and commercial fishermen complain of decreased catches. Damage caused by alien insects cost $20 billion. If they are aggressive colonizers adapted to living in marginal habitat, introduced species can drive resident natives from their established sites and food sources, especially around the disturbed environments of human settlement. A tiny section of stem and leaves accidentally introduced into a lake by a boat or boat trailer can grow into a huge mat covering an entire lake. Because of this isolation, Hawaii originally had thousands of species that existed nowhere else on Earth.

They can also be caused by a natural disaster. Often these plant and animals turn out to be better competitors because, unlike native species, they have no natural pests, parasites , diseases, or predators in their new home. They can be hardy, adaptable to diverse habitat conditions, and able to thrive on a variety of food sources. New York: Natural History Press, 1966.

An exotic species is any species--plant, land- or water-based animal, fungus or bacteria--that is introduced, either by accident or on purpose, to an environment other than where it evolved and historically lived. Humans have always carried plants and animals as they migrated from one region to another with little regard to the effects of these introductions might have on their new habitat. The federal government's Office of Technology Assessment has estimated that more than 2,000 plant species introduced from around the world currently live and thrive in the United States, and that 15 of these have caused more than $500 million worth of damage. Research has shown that more than 40 percent of species on the U.S. Department of the Interior's lists of endangered or threatened species are at risk primarily because of nonindigenous species. It has been spread by barge traffic into all the major East Coast rivers of the United States that are connected through canals to the Great Lakes. .

There are probably about 10 billion colonies. Because there are no other nocturnal, insectivorous lizards in areas the gecko have colonized, it does not appear to be causing any environmental damage. Therefore, it is a type of exotic species but it particularly became a nuisance because it “invaded” and outcompeted the native species in the local ecosystem. Their aggressive foraging and breeding habits often drive native sparrows, martins, and bluebirds from their nests, and today they are one of the most common birds in North America.
