The Miller Seed Vault is the largest vault of its kind in the Pacific Northwest. Seeds are stored in the vault for species protection research purposes and possible future restoration projects.

The mission of the Miller Seed Vault is to:

  • collect and conserve seed of more than 320 rare plant species in Washington,
  • conserve seed of native species for use in restoring native plant communities following a natural disaster, and
  • conserve seed of horticultural varieties not commonly used today.
