A seed bank is a repository for seeds kept safe and viable for as long as possible, which if done correctly can be years or even centuries. It’s been going on, in one form or another, for milennia, as farmers saved excess seeds for times of drought, pestilence, and the like. There are currently about 1400 seed banks spread all over the world, with one, the Svaldbard Global Seed Vault, otherwise known as the “Doomsday Vault,” serving as a backup for all of the others.
First, researchers decide what seeds to collect. Then researchers collect the seeds manually with tweezers, pole cutters, seed traps or nets and buckets, depending on the type of plant. For each collection, they record details like location, plant description, habitat, soil type and other information to ensure optimal replanting conditions. Collectors then assign each sample a unique number. Collectors clean each sample to ensure high quality. Seeds can be cleaned by shaking them through a sieve or with a machine that blows air on them. Collectors dry them in a temperature- and humidity-controlled room. Afterwards, they place the seeds in sealed, airtight containers. The final storage step is to freeze the seeds at minus 4 degrees Fahrenheit (minus 20 degrees Celsius).
