An extraordinary array of willow thickets, marshes, meanders and ponds dotted the landscape during the 1872 General Land Office Survey of the Nevada Spring Creek ranch. 130 years of grazing and haying destroyed much of that habitat, but the underlying soils and seed bank remained. In recent years, wetland dependent species of wildlife traversed the area but few stayed in the hostile environment of grazed pasture and hay lands.

Frontier Resource Management, Inc. (now Eco-Asset Management, LLC) the implementation contractor, has garnered experience from years of wetland restoration and techniques used successfully to restore over 3,000 acres of forested, scrub-shrub and herbaceous wetlands nationwide. Based on this expertise, the sponsor has undertaken to bring back much of the native thickets and marshes observed by Lewis and Clark on their journeys through the area.

By restoring natural water flow patterns, removing weedy plants, changing grazing patterns and installing over 30,000 individuals of native plant species, the robust wetland habitats of the Nevada Creek Valley are being re-established. With these restorations come the ducks, geese, shore birds, grizzly, elk and other species drawn to this wonderful habitat type Thoreau called the "sanctum sanctorum."
