Not sure how many people have followed this. In November 2013 AZ game & fish transplanted 31 desert bighorn sheep from Yuma to the Catalina mountains near Tucson. Four months later there are only 15 sheep left. The goal was to transplant 30 sheep for three years for a total cost of $600,000 and get the population around 100. The original sheep in this area all died off and they were hoping to reestablish the heard.

I am all for the bighorn sheep and hope to draw a tag one day. I think trying to reestablish sheep in an area where hunting is off limits and where they have shown they can't survive due to human impact and too many predators is not the greatest of ideas. Just my two cents.
