A seed bank is a type of gene bank that stores seeds as a source for planting in case seed reserves elsewhere are destroyed. The seeds stored may be food crops, and/or those of rare species to protect biodiversity.
Example of Seed Bank:
An onsite seed bank in In situ conservation sites aims to preserve various seed diversity in their natural environment. By allowing evolution to happen in the natural environment, conservationists are hoping to preserve the best gene that is strong and well adapted to its native environment.
