Dunham is home to more than 270 different native plants as well as grassland and marsh birds, including rare northern harriers, dickcissels and grasshopper sparrows. 

Since 2008, the Wayne Area Conservancy Foundation has helped the Forest Preserve District fund, install and maintain more than 150 different types of of flowers and grasses on more than 135 acres of native short-grass prairie.

The Forest Preserve District acquired Dunham in 2006. Before then, the land was primarily used for agriculture.

A new 1.2-mile trail, scenic overlook, 2-acre picnic area and 25-car parking lot opened at the preserve in October 2020 to provide the first public access to Dunham, which features 212 acres of restored prairie and wetlands.

The restoration work was a multiagency effort with 135 acres of prairie funded, planted, and partially maintained by the Wayne Area Conservancy; 11 acres of wetlands mitigated by Canadian National; and 27 acres of wetlands funded by DuPage County Stormwater Management.
