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.
