Each conservation accession is more than a packet of seed. It is a documented
genetic sample tied to species identity, collection location, habitat, source
population, collection date, and regional provenance. Those records preserve
the biological meaning of the collection for future research, propagation,
restoration, and species recovery.
For species whose seeds tolerate conventional seed banking, material is cleaned,
dried to an appropriate moisture level, sealed in moisture-resistant or hermetic
archival packaging, and maintained in approximately −20 °C long-term conservation
storage. Duplicate material can be maintained in geographically separated
facilities so one hurricane, flood, fire, equipment failure, or other disaster
does not destroy an entire accession.
Species that cannot tolerate conventional drying and freezing require different
solutions, including living collections, propagation, tissue culture, cryogenic
techniques where appropriate, and other species-specific preservation methods.
- Documented source population and regional provenance
- Long-term seed conservation where biology allows
- Geographically separated duplicate material for resilience
- Living, tissue-culture, or other pathways for exceptional species
