The fields of non-native grasslands along Eola road, provide the best habitat on site for grassland birds. For convenience, the grasslands can be divided into three parts. The "North Eola Grasslands" occupy both sides of Eola north of Batavia rd. The "Dog Training Area" lies to the east of Eola, between Batavia rd. and Swenson rd. The "South Eola Grasslands" are also east of Eola, but south of the canal connecting Lake Law to Swenson rd. pond. Each summer since year 2000, Henslow's Sparrows have been found in at least one of the three sections. Sedge Wrens and Grasshopper Sparrows are regular breeders in the "South Eola Grasslands" and until recently a pair of Upland Sandpipers were regular summer residents of the "North Eola Grasslands". This area has also been a fairly regular wintering site for Short-eared Owls and when there is a good snow cover, both Snow Buntings and Lapland Longspurs can sometimes be seen feeding along the edges of the road.

There are a couple of low areas in the "North Eola Grasslands" which usually hold water throughout the Spring. These pools have produced a number of rarities such as Tundra Swans, Cinnamon Teal (1998), and Yellow-headed Blackbirds. Pied-billed Grebes have been found nesting in these ponds on several occasions.
