With more and more plants at risk of extinction, seed banks offer a way to preserve some species, with techniques becoming more sophisticated as time goes on to meet the challenges. A short BBC article and clip gives an overview of the work taking place.
“It's an insurance policy against extinction in the wild…In situ conservation, in a reserve, is always the best, because then evolution can happen all the time. This is a very cost-effective back-up in case that system fails."
