Technical Abstract: The primary purpose of a conservation collection is to support species' survival and reduce the extinction risk of globally and/or regionally rare species. A conservation collection is an ex situ collection of seeds, plant tissues or whole plants that has accurate records of provenance, differentiated maternal lines and diverse genetic representation of a species' wild populations. To be most useful for species survival in the wild, a conservation collection should have depth, meanng that it contains seeds of at least 50 unrelated mother plants from each population, and breadth, meaning that it consists of accessions from multiple populations across the range of the species. Conservation collections of seeds should have initial germination and viability testing, developed cultivation protocols, and periodic long-term viability testing.
