Collections of 3000 seeds or greater maximize the flexibility of the collection and allow for a portion of the collection be held at a second seed bank. Maximizing the use of the collection means that: sufficient seed is available for germination and viability testing; samples are available for supply to users for restoration, education or scientific purposes; and a substantial amount of seed can be conserved as a long-term safeguard against loss of the wild population (Bureau of Land Management 2016).
