As a result of the O’Dell Creek restoration, Granger Ranches has documented a 900% increase in waterfowl species and a 600% increase in species diversity. The ranch now hosts at least fifteen species of concern, including the American White Pelican, Clark’s Grebe, Great Blue Heron, White-Faced Ibis, Franklin’s Gull, Caspian Tern, Long-billed Curlew and American Bittern, Baird’s Sparrow, McCown’s Longspur, Sprague’s Pipit, Burrowing Owl, Short-eared Owl, Ferruginous Hawk. Trumpeter Swans, once gravely imperiled, take refuge on the ranch with 20-50 wintering annually. Raptor species increased from four to ten. Up to 5,000 Rocky Mountain Sandhill Cranes now make annual migratory visits. The wetlands are also supporting river otters, moose, deer, and rare and sensitive flowers.
