The problem of invasive exotic plants, including the melaleuca, Brazilian pepper, Australian pine, old world climbing fern, hydrilla weed and water hyacinth - to name a few - has long been known. Having little controls (such as diseases, predators, and parasites) on their populations in the Everglades ecosystem they have been introduced into, their populations have exploded -- growing over and killing many of the native plants while providing no food and/or shelter the native wildlife is adapted to.
In recent years, the explosion of invasive exotic animals has become apparent as several species of pythons and other snakes, iguanas, birds and fish are now regularly sighted in the wetlands, pinelands, and hammocks.
Pick one invasive exotic animal or plant threatening the Everglades from the list above or from your research on the web. Select a species that has not already been chosen by another student. Name the species or organism in your subject heading so other students can see your choice. Research what is known about how it got there, the extent of the problem, specific threats it poses to the Everglades, and what is being done to control its population. Be sure to include the source of your information. Note that wikipedia is not considered a reliable source.
