Rank ReasonsMaianthemum trifolium is a wide-ranging perennial herb occurring in northern North America throughout Canada and in the northeastern United States from Maine south to New Jersey and west to Minnesota, and northeastern Asia. Threats include development, rights-of-way maintenance, logging, recreational activities, succession, hydrological alteration, invasive species, and deer browsing. 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 CommentsMaianthemum trifolium occurs in northern North America throughout Canada and in the northeastern United States from Maine south to New Jersey and west to Minnesota, and northeastern Asia (FNA 2002).
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 1,500 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, logging, recreational activities, succession, hydrological alteration, invasive species, deer browsing, 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.
