 Regional Invasive Species Database

Exotic species are identified as species of plants, animals, fungi and microorganisms that are introduced to new geographic areas where they do not naturally occur. Invasive species are those exotics that establish reproducing populations that spread throughout the new area, where they may cause ecological, economic, or social harm. Most invasive species are spread through pathways of invasion - human activities that result in intentional or unintentional movement and introduction of species to new areas. The Gulf Coast region includes many different introduction pathways. It is also home to a diverse array of ecosystems ranging from humid, semi-tropical coastal habitats to bottomland forests, arid deserts and mountains. These combined factors lead to a large number of invasive species being found in the Gulf Coast region. The Regional Invasive Species Database provides information describing over 250 invasive species found in the Gulf Coast region, including Species fact sheets, Introduction Pathways, Photographs, Taxonomic information provided by the USDA Integrated Taxonomic Information System (ITIS) and Bibliographic citations.
