GRAND TETON NATIONAL PARK, Wyo. (AP) — Grand Teton National Park reports a decline in collisions involving wildlife and vehicles last year compared to the year before.

Park officials say 103 animals were hit or killed in the park by vehicles in 2011, down from 162 animals in 2010.

Park Superintendent Mary Gibson Scott says the reduction is welcome news. She says the park staff has tried for years to reduce accidents through a public awareness campaign.

The park in November permanently reduced the speed limit to 45 mph on the highway that runs from Grand Teton's southern boundary to its eastern boundary beyond Moran Junction. The park also erected warning signs.
