•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.
