Rank Reasons
Lysimachia hybrida is a wide-ranging perennial herb in a variety of wetlands occurring primarily in eastern and central North America, irregularly westward, from New Brunswick west to Alberta, Canada south to Florida west to Oklahoma, New Mexico and Arizona, disjunct in Washington, United States. Threats include livestock grazing, invasive species, hydrological alteration, rights-of-way maintenance, succession, recreational activities (especially off-road vehicles), deer browsing, drought, and other threats in some places. More information is needed to assess threats and trends. With a large range extent and large number of occurrences, this species is considered secure.
Range Extent Comments
Lysimachia hybrida occurs primarily in eastern and central North America, irregularly westward, from New Brunswick west to Alberta, Canada south to Florida west to Oklahoma, New Mexico and Arizona, disjunct in Washington, United States (FNA 2009). Range extent was estimated to be over 6 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 Comments
By 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 230 occurrences rangewide (GBIF 2024, iNaturalist 2024, NatureServe 2024, SEINet 2024).
Threat Impact Comments
Although threats are not widely documented, this species is threatened by livestock grazing, invasive species, hydrological alteration, rights-of-way maintenance, succession, recreational activities (especially off-road vehicles), deer browsing, drought, and other threats in some places (NatureServe 2024). There is insufficient data, including anecdotal accounts, to understand the scope and severity of threats for this taxon.
