Why You Should Visit

Dedicated as a State Nature Preserve in 1989, Ober Savanna Preserve in Starke County features an exceptionally high-quality black oak sand savanna—a globally endangered ecosystem. Large black oaks are scattered throughout the area with a gorgeous array of wildflowers and grasses underneath. It's even home to Indiana's only native cactus—the prickly pear cactus!

What The Nature Conservancy is Doing/has Done

Conservancy staff and volunteers have manually removed invasive species, and prescribed burns have been used to open up the sire and create ideal conditions for herbaceous sand savanna plants and the lupine—a necessity for the rare Persius duskywing butterfly.




Open year-round from dawn to dusk.

What to See: Plants and Animals

Set among rolling sand hills and ridges, this globally endangered natural community is home to the state-threatened yellow wild indigo, cream wild indigo, and globally endangered fame flower. Numerous butterflies—like the dusted skipper, mottled duskywing and cobweb skipper—and insects are found among the abundant wildflowers such as prickly pear cactus, bluebonnets, Carolina rose, sand cherry, bird-foot violet, and wild lupine.

The preserve is open for visitation. However, there are no trails but the terrain will make for an easy hike.
