How do seed banks at botanical gardens protect plant biodiversity?

Seed banks at botanical gardens serve as vital ex situ conservation tools that protect plant biodiversity by acting as a safeguard against extinction.12

These facilities protect plant life through several key functions:

• Genetic Preservation: Botanical gardens maintain extensive collections of seeds to preserve the genetic diversity of rare, threatened, or endangered species. By storing these seeds, gardens ensure that species facing threats in the wild have a backup repository.1
• Restoration Support: Beyond mere storage, the seeds held in these banks are actively used for restoration projects, helping to reintroduce or bolster plant populations in their natural habitats.1
• Global Collaboration: Institutions like the Millennium Seed Bank Partnership at Kew Gardens coordinate with botanical gardens worldwide to create a massive, shared resource. This collaborative effort has successfully banked seeds representing a significant portion of the world’s wild plant species.1

By maintaining these collections, botanical gardens ensure that even if a species is lost in the wild, its genetic material remains available for future research and conservation efforts.1
