Acres: 180 Total: Finger Prairie 20 acres and West Tract Prairie 160 acres.
Description: This RNA is comprised of three separate tracts, two areas known as the West Tract Prairie and one known as the Finger Prairie, which are remnants of the Marengo and Little Scherrar Prairies. This RNA represents undisturbed and recovering dry sand prairies and oak savannahs characterized by sparse woody vegetation such as pin oak (Quercus palustris), black oak (Quercus velutina), and eastern white pine (Pinus strobus). Two state threatened species, prairie smoke (Geum triflorum) and western silvery aster (Aster sericeus), and three state species of special concern, grooved yellow flax (Linum sulcatum), false arrow-feather (Aristida necopina), and Allegheny-plum (Prunus alleganiensis), are present within the RNA.
Nearest weather station, with distance and direction from RNA: Weather observations, dating from 1907, are available from Croton Dam and Hardy Dam. Croton Dam is located within 4 miles (6.4 km) of all three segments of the RNA. West Tract Prairie is 3 miles (4.8 km) to the northwest, and Finger Prairie is 4 miles (6.4 km) to the southwest. Hardy Dam is located 4 miles (6.4 km) upstream of Croton Dam.
Annual precipitation (type, seasonal distribution) : The mean annual precipitation is 32 inches (80 cm), 56% of which falls from May through October. Mean annual snowfall is 57 inches (145 cm).
Maximum and minimum temperatures : The annual mean temperature is 45.5 ºF, and the mean January temperature is 21.7 ºF.
Elevation: Finger Prairie - 804 feet (245 m); West Tract Prairie - 800 feet (244 m)
Geology and Soils: A layer of glacial drift several hundred feet thick covers the bedrock on the prairie locations. The three RNA tracts are located exclusively on Sparta loamy sand. Adjacent forested land is growing on Plainfield sand.
Aquatic Features: Surface water is limited to a seepage wetland.
