NatureServe Conservation Status

Rounded Global Status Rank: T2 - Imperiled

Reasons: Endemic to the Florida Keys, where currently known only from Big Pine Key in Monroe County, Florida. Threatened by habitat alteration, altered fire regime, development and non-native plants. The habitat of Chamaecrista lineata var. keyensis is very uncommon; these plants occur only on the edges of rockland hammocks and pinelands in the pine rocklands. Given its narrow habitat range, and the small number of individuals that occur, Chamaecrista lineata var. keyensis is vulnerable to extinction if these threats continue.

Environmental Specificity: Very narrow. Specialist or community with key requirements scarce.

Comments: Pine rockland endemic. Very little pine rockland habitat remains in the Florida Keys or elsewhere.
