Hoosier Prairie State Nature Preserve, Protected prairie in Lake County, Indiana, US.
Hoosier Prairie State Nature Preserve is a 1,547-acre protected area in northwest Indiana featuring dry black oak barrens, wetland pools, and wet prairie grasslands across rolling sandy terrain. The landscape shifts between open grassy areas and wooded sections, creating diverse habitat types throughout the property.
The land gained protected status in 1977 through conservation group efforts, expanding from an initial 304 acres through strategic land acquisitions. This gradual expansion transformed it into an important refuge for rare habitats in the region.
The preserve holds over 350 native plant species that represent Indiana's natural heritage. Visitors can spot wildflowers like white wild indigo and Indian paintbrush scattered across the landscape.
The preserve is open daily from sunrise to sunset with free admission and parking at the entrance. Visitors can explore the grounds on wheelchair-accessible gravel paths and bark-covered trails that wind through different habitat areas.
The sand formations date back about 13,000 years to the Glenwood Spit period and create a complex mix of dry and wet areas. These ancient deposits allow 43 rare plant species to thrive here, species found nowhere else in Indiana.
