Most of northern Illinois was tallgrass prairie at the time of statehood in 1818. In the ensuing century, the vast majority of this prairie was plowed up for arable farmland. [ 3 ] A Nature Conservancy planning process, aimed at building a restored tallgrass prairie ecosystem in Illinois, commenced in 1985; the first major land acquisition of ...

Flowering big bluestem, a characteristic tallgrass prairie plant. The tallgrass prairie is an ecosystem native to central North America.Historically, natural and anthropogenic fire, as well as grazing by large mammals (primarily bison) provided periodic disturbances to these ecosystems, limiting the encroachment of trees, recycling soil nutrients, and facilitating seed dispersal and germination.

Illinois' ecology is in a land area of 56,400 square miles (146,000 km 2); the state is 385 miles (620 km) long and 218 miles (351 km) wide and is located between latitude: 36.9540° to 42.4951° N, and longitude: 87.3840° to 91.4244° W, [1] with primarily a humid continental climate.
Native plant persistence in cemetery prairies is highly variable, as one 1970s-era survey of Illinois and Indiana prairie cemeteries detailed: [19] "In each cemetery, certain prairie indicator species were sought, especially the warm-season grasses, such as big bluestem (Andropogon gerardii Vitman) and Indian grass (Sorghastrum nutans (L.) Nash).
The tallgrass prairie ecosystem covered some 170 million acres (690,000 km 2) of North America. Besides agriculture, much of the shortgrass prairie became grazing land for domestic livestock . Short grasslands occur in semi-arid climates while tall grasslands are in areas of higher rainfall.
