•Millennium Seed Bank Project

storing seeds for future use

Launched in the year 2000

consist of large underground frozen vaults

preserving the world's largest collection of

seeds

collect the seeds from 24,000 species of

plants by 2010, representing 10% of the

worlds dryland flora, (achieved October

2009.[

seeds are germinated on a periodic basis,

typically every 10 years.

Special:Se

Spitsbergen was considered ideal due to

its lack of tectonic activity and its

permafrost, which will aid preservation.

The location 130 metres above sea level

will ensure that the site remains dry even if

the icecaps melt.[4] Locally mined coal

provides power for refrigeration units that

further cool the seeds to the internationally

recommended standard −18 C (0 F).[5]

Even if the equipment fails, at least several

weeks will elapse before the temperature

rises to the −3 C (27 F) of the

surrounding sandstone bedrock.[1]

Prior to construction, a feasibility study

determined that the vault could preserve

seeds from most major food crops for

hundreds of years. Some seeds, including

those of important grains, could survive far

longer, possibly thousands of years.
