In 1994, the Illinois Nature Preserve Commission designated the prairie as an Illinois Nature Preserve. Only sites with statewide ecological value are considered for this highest level of protection under Illinois law. This unique prairie land, with its rolling terrain, oak savanna and conifer groupings, is home to several rare and endangered plant and animal species including the Prairie Buttercup, Pinweed, Queen of the Prairie, Pale Vetchling, Purple Flowering Raspberry, Silvery Blue Butterfly, and the Franklin Ground Squirrel. During its active months from spring to fall, the prairie is in constant bloom.
Nature lovers are welcomed by hiking trails that are moderate to very hilly that meander through the prairie. From hill to hollow, the type of native vegetation waiting to be discovered varies. A flat moraine at the northern end of the site is home to yet another variety of plants not requiring the well-drained soil of the hills or the damp hollow areas.
