Saturday marks the 20th anniversary of National Trails Day, which evolved from President Reagan's Commission on the Americans Outdoors.

Theprogram is being expanded under the Obama Administration's Great Outdoors initiative.

"Under the Americas Great Outdoors initiative we're reconnecting metro Denver with an existing trail system," said Steve Guertin, the Regional Director of the U.S. Fish and Wildlife Service. "We're going to connect the Rocky Mountain Arsenal and the Rocky Flats Arsenal so that folks can take advantage of 500 miles of trails here in the urban area."

As a part of that project a trail will also be added to connect the Two Ponds National Wildlife Refuge in Arvada to the existing system along with the Rocky Mountain Arsenal and Rocky Flats to form the Rocky Mountain Greenway.

The Greenway will include neighborhood trail links along with multiple trailheads able to accommodate cars, horse trailers, horses and bikes.

According to the Fish and Wildlife service, protecting this land will also enhance movement corridors for wildlife especially along prairie riparian zone which are crucial to many species.

In celebration of National Trails Day and the planned expansion, the Arvada Celebrates its Trails program has partnered with Two Ponds National Wildlife Refuge and Majestic View Nature Center for a series of family friendly events.

From 10 a.m until 2 p.m. Saturday at the Two Ponds national Wildlife Refuge there will be a variety of environmental education displays and activities for kids and adults, including live birds of prey, self-guided nature walks on the Refuge's trail system, wildlife contraband viewing and wildlife photography as well as educational offerings from Mad Science, Birds of Prey Foundation and theColorado Division of Wildlife.

At 11:30 a.m. a re-dedication ceremony will be held culminating with speeches by keynote speakers Ed Perlmutter, Representative 2nd Congressional District and Stephen Guertin, Regional Director of the U.S. Fish & Wildlife Service.

The Majestic View Nature Center activities will include live animal appearances by the Denver Zoo and the Butterfly Pavilion, a wildlife workshop and reptile/amphibian presentation by the Colorado Division of Wildlife, a native plant sale, nature exhibits, bird walks, kids' environmental activities and a presentation by Arvada Animal Management.
