In 2021, CPC contracted California Botanic Garden 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.
Lilium parryi occurs in southern Arizona and southern California. It is rare in Arizona, where it is extant in 2 canyons in the Huachuca Mountains. Most occurrences in Los Angeles County, California are very small and it was nearly extirpated from San Diego County. Major threats include horticultural collecting, water diversion and grazing. Other threats are air pollution, timber cutting and pesticide effects on pollinators.
Part of one population occurs on Nature Conservancy land, and so is protected and managed for, and the plants there are candidates of source seeds for restoration work.
Suggested research studies include pollination biology studies and assisted pollination and seed dispersal work
Suggested management projects include moving trails away from populations and obtaining water rights on land where the species occurs to ensure that hydrology is not altered.
Be sure that seeds are collected and banked for all known populations, especially the genetically unique Turkey Creek population, to ensure proper genetic variation for future reintroduction work.
Small population size
(Arizona Fish and Game Department 1999)
7 populations, 6 of which are stable in Ramsey Canyon
Plants found in Turkey Creek in the Chiricahua Mountains of Arizona are genetically unique suggesting that they have been isolated for a long time. The majority of the other Arizona populations had little genetic variability (Friar et al. 1996).
