Rank Reasons
Platanthera lacera is a perennial orchid found throughout eastern North America. Threats include the destruction of wetland bogs, peat mining, invasive species, logging, development, and likely other threats in some places. With a large range extent, more than 1,500 occurrences, abundant habitat, and broad habitat preferences, this species is considered secure.
Range Extent Comments
Platanthera lacera is native to a wide area of the eastern United States and Canada from Manitoba to New Foundland south to Texas and Georgia. Range extent was estimated using herbarium specimens and photo-based observations documented between 1993 and 2024 (GBIF 2024, iNaturalist 2024, SEINet 2024).
Occurrences Comments
By applying a 1 km separation distance to herbarium records and photo-based observations documented between 1993 and 2024, there are estimated to be more than 1,500 occurrences rangewide (GBIF 2024, iNaturalist 2024, SEINet 2024).
Threat Impact Comments
The destruction of wetland bogs is a low-level threat to this species (Southern Appalachian Species Viability Project 2002). Additional threats include peat mining, invasive species, logging, development, and likely 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. However, their overall impact is likely negligible given the species' broad range, large number of occurrences, tolerance of light disturbance, and affinity for typically abundant habitats, as well as no obvious intrinsic vulnerabilities.
Ecology & Habitat

Habitat

Platanthera lacera grows in sphagnum bogs, alluvial and swamp forests, stream banks, riparian meadows, sand flats, moist and seeping slopes, prairies, roadside banks, ditches, old fields, and borrow pits (FNA 2002).
