  • Seed Collection

The California Botanic Garden made a conservation seed collection of the population of Castela emoryi (Crucifixion thorn) located in the Crucifixion Thorn Natural Area near Ocotillo in Imperial County, California on March 8, 2021. This is a recollection of the 2004 seed collection made by Michael Denslow (CalBG Accession #21337), and a seed sample was sent to the National Laboratory for Genetic Resources Preservation for use in the CPC/IMLS RNA Integrity Study.

  • Orthodox Seed Banking

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.
