The California Native Plant Society collected fresh seeds of Mariposa clarkia, Clarkia biloba subsp. australis, in 2023 for the IMLS Seed Longevity from a wild population at McCabe Flat Campground on BLM land in Mariposa County. CNPS staff did an initial survey of the population on June 7. Congeners were present and we identified and mapped areas where only C. biloba subsp. australis was present. We returned to collect seeds from these areas on August 2, 2023.

In 2021, CPC contracted the California Native Plant Society to recollect seed from a population currently held in long term orthodox seed storage as part of an IMLS-funded seed longevity experiment. The National Laboratory for Genetic Resources Preservation will evaluate how germination tested viability and RNA Integrity of seed lots decline over time in storage.
