Such seeds generally germinate prior to the next round of seed production, and the seed bank is thus continually depleted and reestablished. Preservation of Crop Diversity This is the most important reason for the storage of seeds. The tree seed density in the pasture seed bank was much lower (21/m2) than the density in the seed bank of a neighboring secondary forest (402/m2). A gene bank is what scientists call any effort to conserve genetic diversity, in order either to keep species from becoming endangered or extinct, or to preserve the variety within a species.For both plants and animals, the ideal gene bank is a natural habitat that is protected from destruction. seed bank studies can, at least partly, be attributed to the way that seed banks versus the established plant communities are sampled. These events can lead to huge losses of plant life quickly. The seeds of some plant species can be remarkably long-lived, extending the life of the seed bank.
