What did the Fish and Wildlife Service (FWS) do to bring back black-footed ferrets from extinction?

The FWS moved mating pairs from the Wyoming population to over 8 western states and Mexico to begin new colonies.

The captive breeding program was implemented too late to save the black-footed ferret.

The FWS monitored a Wyoming population and captured enough individuals to start new populations.

The FWS use a captive breeding program to start populations in 8 states.
