Q

What are the chances that the new popula+on will be successful/viable?
What do you need to know to answer this?

–  Are mul+ple release sites necessary?
–  Should the sex ra+o and age structure of released popula+on be
balanced?
–  Will the released individuals socialize and func+on normally?
–  Will cap+ve-raised animals know where to forage, know where/how
to migrate? Eg. Whooping Cranes
