Rank ReasonsPluchea odorata is a wide-ranging annual or perennial forb primarily in salt or brackish marshes and estuaries but also in a variety of inland wetlands occurring in North America from Ontario, Canada, the Great Lakes region, and Maine south to Florida and west to California in the United States, south to Mexico and throughout Central America, and into South America and the West Indies with two varieties. Threats potentially include development, rights-of-way maintenance activities, recreational activities, and invasive species. Little is known about trends, but with a large range extent and large number of occurrences, tolerance of light disturbance, and no obvious intrinsic vulnerabilities, this species is considered secure.
Range Extent CommentsPluchea odorata occurs in North America from Ontario, Canada, the Great Lakes region, and Maine south to Florida and west to California in the United States, south to Mexico and throughout Central America, and into South America and the West Indies (FNA 2006). See individual entries for distribution details about the two varieties. Range extent was estimated to be over 20 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 thousands of 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, invasive species, and other threats in some places. However, their overall impact is likely negligible given the species' broad range, large number of occurrences, tolerance of light disturbance, and no obvious intrinsic vulnerabilities.
