The Red Wolf has been reintroduced to several counties in my state....only issue there is the encroachment of coyotes in my state and in those counties where the red wolf is being reintroduced they've stopped allowing the taking of coyotes as the two species look extremely similar. Coyotes cause a lot of troubles by harming turkey and white tail deer populations. Also coyotes and red wolves will probably create hybrids after a while.
