Cougars: A Keystone Species
Where there are cougars, there are healthy deer populations and grasslands.
"To my mind, these live oak-dotted hills fat with side-oats grama, these pine-clad mesas spangled with flowers, these lazy trout streams burbling along under great sycamores and cottonwoods, come near to being the cream of creation."
Aldo Leopold, referring to the Sky Islands of SW New Mexico and SW Arizona; A Sand County Almanac
