The slender sandwort has been listed as threatened in Illinois, and endangered in Indiana and Ohio by the United States Federal Government (8).
Recommended conservation measures for the slender sandwort include protecting, managing and restoring suitable habitat areas, maintaining genetic viability and creating a seed bank for future reintroductions. To maintain the native habitat of this species, it is important that grazing is minimised and any non-native vegetation is removed. Preventing other activities such as trampling by animals or humans and the collection of wild specimens for non-scientific purposes would also be beneficial to wild populations of the slender sandwort (5).
Research on this species’ life history, natural distribution and habitat requirements is also needed to determine the exact population structure and the extent to which it is changing (5).
