The Pine Ridge in northwestern Nebraska is the only area with evidence of a resident reproducing population. The Nebraska Game and Parks Commission documented the first instance of reproduction here in 2007 when a kitten was photographed with a female for the first time. The Pine Ridge is the largest area of suitable habitat in Nebraska with the beautiful buttes, cliffs, canyons and forests creating prefect habitat for mountain lions. Other areas like the Niobrara River Valley and Wildcat Hills have excellent habitat and many confirmations of mountain lions but lack proof of reproduction at the present time.
