Ex-situ conservation means conservation of wild life outside their natural  habitat. If wild species are vulnerable in their habitat due to activities of human or environmental causes, they are shifted to different  place and grown for study and entertainment purposes. Some examples are botanical garden, zoological park, seed banks, tissue culture banks,  gene bank.
