AVLT conservation easement donor Bob Child was posthumously awarded the 2004 Wildlife Landowner of the Year award by the Colorado Division of Wildlife. This prestigious award recognizes the important contributions private landowners make to improve habitat for wildlife, and to provide public access to wildlife on their properties. Pitkin County (a partner in the preservation of the Child's ranch) and AVLT nominated the Child family for this award in recognition of their efforts to preserve their 1,500-acre Capitol Creek Ranch and its diverse wildlife habitats, while maintaining its heritage as a working cattle ranch. The Child ranch - located in the pristine upper reaches of the Capitol Creek Valley in Snowmass, Colorado - is a model of balance between conservation, public access, and agricultural heritage. 

Bob and Tee Child purchased the ranch in the early 1960s, and ranched it quitely until 1969, when their way of life was threatened by a proposal to turn nearby Haystack Mountain into the valley’s fifth and possibly largest ski area. Bob Child led the battle against the proposal in the local political arena for ten years until he convinced Congress to designate the land as wilderness. Instead of succumbing to the lure of development dollars, the Child family chose to place 98% of their ranch in conservation easements over the next ten years. They have also worked hard to ensure that the public has access to the neighboring wilderness by granting Pitkin County a trail easement across their property to the federal lands beyond. Hunters, anglers, hikers, horseback riders, cross country skiers, local school children, and a variety of other recreation users have all benefited immensely from the Child’s selfless vision for their property.
