Control of NATL's invasive exotic plants

Species of concern (1994-2012)


Of the 534 species of vascular plants known from NATL, 142 are not native to Florida, but only 21 of these made this list in 2004 because of their perceived potential to significantly alter NATL ecosystems. The species making the list were divided among four categories, which are listed below in order of decreasing threat. Each listed species is linked to its page in "Atlas of Florida Vascular Plants" and to text and maps describing its status and control through May 2012.
