Rank ReasonsLechea intermedia is a wide-ranging perennial herb in a variety of open habitats occurring in northeastern and north central North America from Nova Scotia west to Alberta, Canada south to Virginia and Illinois west to Wyoming in the United States with four varieties. Threats include development, rights-of-way maintenance activities, recreational activities, succession, and invasive species. Little is known about trends, but with a large range extent and large number of occurrences, abundant habitat, broad habitat preferences, and no obvious intrinsic vulnerabilities, this species is considered secure.
Range Extent CommentsLechea intermedia occurs in northeastern and north central North America from Nova Scotia west to Alberta, Canada south to Virginia and Illinois west to Wyoming in the United States (FNA 2015). See individual entries for distribution details about the four varieties. Range extent was estimated to be almost 4 million square kilometers using herbarium specimens, photo-based observations, and NatureServe Network occurrence data documented between 1993 and 2024 (GBIF 2024, iNaturalist 2024, NatureServe 2024, SEINet 2024).
Occurrences CommentsBy applying a 1 km separation distance to herbarium specimens, photo-based observations, and NatureServe Network occurrence data documented between 1993 and 2024, it is estimated that there are over 300 occurrences rangewide (GBIF 2024, iNaturalist 2024, NatureServe 2024, SEINet 2024).
Threat Impact CommentsAlthough threats are not widely documented, this species is potentially threatened by development, rights-of-way maintenance activities, recreational activities, succession, invasive species, and other threats in some places. However, their overall impact is likely negligible given the species' broad range, large number of occurrences, and no obvious intrinsic vulnerabilities.
