Simply Sasquatch Breeding Populations

Breeding populations. Just how many do we need out there to make for a species that is prolific enough to survive? Once born, what is the weaning process of the adolescent Sasquatch? What do they do when they become old enough to breed? Do the young males leave to find a mate? Or is it the females, as some tiger species do? Are there any clues or indications that might lead us to a better understanding?
