Millennium Seed Bank

Open all year round the MSB is a hub for scientific activity where visitors can discover more about its vital mission to conserve 25% of the world’s plant species by 2020.

Preserving the world's botanical heritage

'A gold reserve...a place where this reserve currency, in this case life itself, is stored.' So said HRH the Prince of Wales as he opened the Millennium Seed Bank in 2000. 

By storing the world's seeds, the Millennium Seed Bank (MSB) aims to provide an insurance policy against the extinction of plants in the wild.

This is important because plants provide food, building materials, fibres for clothing, medicines and fuel, but also it is preserving our botanical heritage for generations. However the destruction of plant habitats is happening so fast that it is not always possible to conserve plants within threatened habitats.

Collecting seeds and preserving them ex situ (away from their natural habitat) offers an economical and effective way to save seeds and keep them for posterity. In the future, if required, they can be germinated and reintroduced to the wild or used in scientific research

Our progress

The MSB team initially aimed to store seeds from all of the UK’s native plant species. It achieved this in 2009, apart from a handful of species that are either very rare or whose seeds are particularly difficult to store.

This means that Britain is the first country in the world to have preserved its botanical heritage.

The current phase of the project is to conserve 25% of the world’s plant species by 2020 and we are well on our way to achieving this goal

How we work

MSB scientists work with partners in more than 95 countries around the world. Where possible, collections of seeds stored at Wakehurst are duplicated in seed banks in the country where they were collected.

The team focuses on plants

  • from alpine, dryland, coastal and island ecosystems - these are most vulnerable to climate change
  • from arid locations - these can tolerate being dried out and frozen for many years, whereas those from moist tropical areas are harder to store
  • endemic to their location (not found anywhere else), economically important or endangered

The work also helps nations meet international objectives, such as the Global Strategy for Plant Conservation and the Millennium Development Goals of the United Nations Environment Programme.

History and design of the building

The Wellcome Trust Millennium Building replaced earlier cold stores of seeds held at Kew and Wakehurst.

Three glass sections house laboratories, seed-preparation facilities and a public exhibition area. Under these lie a vast storage vault.

The building provides the best possible conditions for seed storage, while maximising energy conservation. And the low-level building with barrel vaulted roofing sits in harmony with the surrounding landscape

MSB parterre

On the parterre outside the MSB building, raised beds evoke eight threatened habitats of the British Isles.

These habitats are shingle beach, chalk cliff, chalk downland and meadow, all of which can be found between the south coast and Wakehurst. Also represented are marsh and fenland, hills and mountains, heathland and cornfield.

Seeds from these habitats are stored in the Millennium Seed Bank to preserve them for future generations
