ABSTRACT: Current extinction rates of plant and animal species are estimated to be as much as 100- to 1000-fold higher than during the recent geological past, a phenomenon that conservation biologists attribute to wide-scale destruction of natural habitats (Pimm et al. 1995). As natural habitats continue to disappear, there have been increasing efforts to stockpile wild plant species in large, centralized seed banks a form of conservation that falls under the general category of ex situ conservation, or conservation outside the native habitat.
