    Charismatic megafauna?

    With numbers and distribution reduced as much as they are for bighorns, why don’t people get as upset about their conservation as wolves and griz?

    Is this all spread by domestic sheep? Why is that bighorn sheep are so prone to pneumonia but you never hear about other ungulates with it?
