Nonnative species are species that are found outside their natural habitat. They are also called foreign species. They are introduced through the activities of man either deliberately or in-deliberately . They can be controlled by chemical, biological and mechanical means.

Mowing, net barriers and inspections are mechanical controls.

Biological control is the deliberate introduction of natural enemies of these nonnative/foreign species.
