A saltmarsh plant has disappeared from one estuary after its habitat was damaged. Before the loss, conservationists collected viable seeds from the plant and stored them.
Why is the stored collection useful?
It preserves the interactions between the plant and other organisms in the estuary.
It causes useful alleles to form while the seeds are in storage.
It allows the plant to survive in the estuary without suitable habitat.
It can provide plants to restore the population after the local loss.
