CSWGCIN Regional Invasive Species Database
Shortcut URL to this page:

The Central Southwest Gulf Coast Region includes many different ecosystems ranging from humid, semi-tropical coastal swamps to arid, mountainous areas. Because of this, the region contains a large number of invasive species including species with a high economic impact and ruderal species. The Invasive Species Database provides baseline occurrence data of invasive species for the region but also details occurrences for areas of particular interest or environmentally sensitive areas like Coastal Plains.

For more information on invasive species in your area, please visit the Invasive Species Information Node of the NBII.
