Yes. Many of the native seeds are on the verge of extinction due to companies like monsanto. In India Native cotton seeds are veey very difficult to find. 95% ppl today grow BT cotton and Farmers who grow BT cotton are commiting suicides from last decade. Native seess require less water and less fertilizers and pesticides. Its a natures gift.. we should strive more to preserve them. In India also people like you are building Seed Banks. All the best to you.
