NatureServe Conservation Status
Rounded Global Status Rank: G2 - Imperiled
Reasons: Endemic to the karst pond area of Bay and Washington counties, Florida, where it occurs on the fluctuating shores of karst sinkhole ponds and small lakes. Within this very narrow geographic and habitat range, the species can be quite locally abundant, often dominating the pond shores where it occurs; occurrences with tens to hundreds of thousands of plants have been documented. Approximately 125-140 occurrences may be extant, although some are in close proximity. Some occurrences are on land owned by the Northwest Florida Water Management District, where they are protected from direct threats. However, occurrences on private lands are threatened by rapid lakeshore development in this region, which can result in clearing of lakeshore vegetation to create beaches. Other threats include erosion from disturbance of the surrounding upland longleaf pine-deciduous scrub oak sandhills matrix (forestry, development, road maintenance), prolonged drought, and recreational use of the lakeshores.
Environmental Specificity: Very narrow. Specialist or community with key requirements scarce.
Comments: Completely dependent on specialized habitat.
