The California Botanic Garden made a conservation seed collection from a population of Boechera parishii (Parish’s rockcress) located near Baldwin Lake in the San Bernardino Mountains of San Bernardino County, California on June 3, 2021. This is a recollection of the 1991 seed collection made by Mike Hammitt (CalBG Accession #17188), and a seed sample was sent to the National Laboratory for Genetic Resources Preservation for use in the CPC/IMLS RNA Integrity Study.
In 2021, CPC contracted the 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.
Based on an September 2020 extract of the California Plant Rescue Database, California Botanic Garden holds 1 accessions of Boechera parishii in orthodox seed collection. There are as many as 1957 seeds of this species in their collection - although some may have been used for curation testing or sent to back up.
Based on an August 2020 extract of the California Plant Rescue Database, California Botanic Garden has collected 1 seed accessions of Boechera parishii from 1 plant occurrences listed in the California Natural Diversity Database. These collections together emcompass an unknown number of maternal plants
