Glacier Creek Preserve is a 212 ha (525 acre) preserve situated northwest of Omaha in the rolling hills of eastern Nebraska. Embedded within the Preserve is the 57 ha (140 acres) Allwine Prairie Tract, a restored tallgrass prairie created in 1970. Large enough to sustain a diversity of functioning plant and animal communities, Glacier Creek Preserve incorporates an entire sub-watershed. This feature protects the preserve against effects of surrounding land use thus reinforcing its sustainability into the foreseeable future as a unique metropolitan area preserve available for education, research, and appreciation of our natural heritage.
