The document discusses restoration efforts at Poplar Creek Prairie to restore oak-hickory woodlands and increase the less than 0.1% of tallgrass prairie remaining in Illinois. It aims to protect plant species, insects, birds and mammals that are interdependent on the prairie ecosystem. Various areas of the prairie are described, including native prairie flower areas, oak-hickory woodlands, a glacial hill nature preserve, and bluebird houses designed to help the declining bluebird population. The prairie restoration efforts over 25 years have helped transform formerly farmed land into a diverse native habitat.
