 Weston Prairie is a surviving fragment from a parcel of land that was set aside by early residents in 1870 to serve as a township cemetery.Although the parcel appears to have fallen out of active use as a burial ground around 1900, part of the parcel escaped the plow and was still in existence in the 1970s when surviving fragments of Illinois tallgrass prairie were located and inventoried.The prairie is noted for exceptional plant diversity, with nearly 100 separate species identified on the tiny site.
