Canis rufus (Red Wolf) is one of the most endangered mammals in North America. However, genes of the Red Wolf persist across much of the species' original range, carried predominantly within C. latrans (Coyote) populations. It is now known that such genes are distributed from extreme north-central Texas through most of eastern Texas to southern Louisiana. Publicizing of the most recent findings of Red Wolf genes in Coyotes of southern Louisiana emphasized that area for intensive conservation efforts. Such efforts could be applied throughout the entire known distribution of those rare genes, not just in the small area of southern Louisiana recently publicized. Because conservation efforts might be hindered by local conditions and circumstances, expanding geographic options for their application could make the difference in their success.
