Are there any animal trainers that trains wild animals how to survive in the wild?

are there animal trainers that train (captive) wild animals to survive in the wild? like for example say like tigers right? and you know how tigers are becoming extinct and there's breeding programs at like zoos, sanctuaries, etc. to keep their populations up and growing and people are trying their best to successfully reintroduce the animals back into the wild and well i was wondering because some of you may know that one day i'll like to become a well-trained professional animal trainer some day and would love to train animals for the movies, television and places like zoos, sanctuaries, animal shelters, etc. but i'll love to also train animals that are becoming endangered how to survive in the wild like reintroduce them in their natural habitat but are there like any animal trainers that do that? training and reintroducing native endangered animals back into their habitats? or just train animals for entertainment, etc. can you help me out here please. thanks.
