I think I could find people to buy from in Colorado who are in favor of a reintroduction plan to build on the handful of wolves that have migrated into the state naturally. I also prefer bison or even yak.
I think you should ask him. If his lively hood solely depends on the livestock he raises I doubt he supports reintroduction. Same goes for the others ... it's easy to support something if there is no risk to you for doing so.
You make a good point, but I think that it's not really a life or death thing for any of these ranchers. Obviously if it was then there should be some mitigation in place (and probably for all of them regardless).
