Rank ReasonsCheilanthes lanosa is a fern found on rocky ledges in forests and prairies of eastern North America from Minnesota east to Connecticut, south to Florida, and west to Texas, United States. There are over 500 occurrences of this species, which are threatened by development, dumping, invasive species, recreation, and deer herbivory. Little is known about trends, but with a large range extent, high number of occurrences, and no obvious intrinsic vulnerabilities, Cheilanthes lanosa is considered secure.
Range Extent CommentsCheilanthes lanosa occurs in eastern North America from Minnesota east to Connecticut, south to Florida, and west to Texas (FNA 1993, Weakley and the Southeastern Flora Team 2024). Range extent was estimated to be 1.4 million square kilometers using herbarium specimens and photo-based observations documented between 1993 and 2024 (GBIF 2024, iNaturalist 2024, SEINet 2024).
Occurrences CommentsBy applying a 1 km separation distance to herbarium specimens and photo-based observations documented between 1993 and 2024, it is estimated that there are over 500 occurrences rangewide (GBIF 2024, iNaturalist 2024, SEINet 2024).
Threat Impact CommentsAlthough threats are not widely documented, Cheilanthes lanosa is threatened by development, dumping, invasive species, recreation, deer herbivory and other threats in some places (NatureServe 2024). However, their overall impact is likely negligible given species' broad range, large number of occurrences, and affinity for typically abundant habitats, as well as no obvious intrinsic vulnerabilities.
