The Hobart Prairie Grove preserves several habitats including wetlands, prairie remnants, white oak flatlands, and a rare bur oak savanna. At about 300 acres in size, it contains 343 native plants and an abundance of wildlife. This area is also noteworthy because of a unique soil that is made up of at least 70 percent silt and clay with the smaller portions of sand. This type of soil is one of the reasons for the outstanding diversity of life here at Hobart Prairie Grove. This very special place was added to the National Park System as part of a 1992 expansion of Indiana Dunes National Lakeshore (renamed the Indiana Dunes National Park in 2019).
