Lot?s of well stated ideas here, Most seem to take a little different road but all come seem to the same conclusion. It?s all management issues. It would be interesting to see a area that had zero wolf population to start with planted with wolves that were sterile. You could monitor the effects and add or take away from the population to sorta dial it in so to speak. The data from a study such as this would be close to that of a natural wolf population on a given area. It just seems all the efforts are geared toward getting a breeding population established in order to save the vanishing wolf with the current environment being a secondary issue. I don?t just a thought, have a good day.
