So what's your stance? I don't think the red wolf should be exterminated, but I do believe that we should stop protecting it, when there are other species to be concerned about. "Protecting" it would basically involve slaughtering every single coyote in the area, to stop them hybridising. The irony is, red wolves simply are coyotes, and obviously want to mate with their own kind. There is nothing particularly special about the red wolf warranting its continued purity: pure coyotes do just as well in regulating deer populations.In both structure and SABER analyses, red wolves appear to have an admixed ancestry with ~75-80% of their genome attributed to coyotes and the remainder to gray wolves... We estimate admixture was initiated 144 generations (287-430 years) ago, placing it approximately in a periodwhen the Southeast U.S. was being converted to agriculture and predators were intensely hunted for fur or as pests... The implications of our results are that a component of the phenotypic distinction of red wolves may be attributed to historic hybridization of distinct populations of gray wolves and coyotes. It has been suggested that hybrids are not clearly protected under the ESA, especially hybrids between nonlisted entities. Since a critical aim of the red wolf recovery project is to maintain the introduced population free from hybridization, the rationale of the program may need reconsidering as the extant red wolves clearly derive from a process of admixture.

I say, let them reabsorb back into the coyote population. It's what they want, and they've only been the way they are for something like 300 years (I know of domestic dog breeds much older than that).
