Bank
Transcript:
The Seed Bank was conceived in 1992 and has been called a Noah’s Ark for plants. The bank has capacity for seeds from half the world’s plants and already holds seeds representing 88 percent of English flora. By 2010, the seed bank hopes to have collected and conserved seeds from 10 percent of the world’s known wild flowering plant species. The billionth seed in the collection is from African bamboo, species name Oxytenanthera abyssinica. The seed comes from Mali in West Africa, where the plant is used for construction and furniture making. But due to over harvesting, African bamboo is now endangered in Mali. It’s a conservation priority because of its usefulness, its threatened habitat, and the fact that it seeds only every seven years. It won’t set seed again until 2013.
