... and the other has one brief mention and suggests that the wolves will need to be "monitored" going forward.

If there are only 4 of them (the caribou, that is) they're not likely to be the primary basis of anything's diet for very long, are they?

I did read the links and I saw a lot more about habitat loss than predation as a cause for the caribou's decline. Historically, wouldn't wolves and caribou have shared this area? Why wouldn't success for wolves be regarded as a success and failure for caribou be regarded as a loss? Why transform the wolf reintroduction success into another loss by deliberately killing them off?

I can buy that there is an argument that we shouldn't try to "fix" stuff because we don't have any control over unintended consequences.

I can also buy that there is a role for "restoration" efforts, potentially.

I'm confused that you seem to favor one approach for the caribou and the inverse and opposite approach to wolves.

Wassup with that?
