FIELD TRIP

Tefft Savanna Nature Preserve

Scott Namestnik

Indiana State Botanist

Saturday September 12, 2026,

10am - noon Central, (11am -1pm Eastern)

Tefft Savanna Nature Preserve is a 480-acre portion of the 8,000-acre Jasper-Pulaski Fish and Wildlife Area. The preserve supports a complex of natural communities which are now rare in Michigan and Indiana. The upland dune ridges support a fire-dependent savanna and woodland dominated by black oak (Quercus velutina) with a shrub layer of blueberry (Vaccinium spp.) and huckleberry (Gaylussacia baccata) and abundant sand-loving forbs and graminoids in the herbaceous stratum. In treeless areas, dry sand prairie is present. Between the ridges are acid flats and depressions comprised of inland coastal plain marsh natural communities in treeless areas and a pin oak (Q. palustris) and black gum (Nyssa sylvatica) overstory in areas that have become forested. Over 260 plant species have been identified in the preserve, and more than 30 of these are listed as threatened or endangered in Indiana.

We will spend our time during this hike exploring the sand prairie and savanna communities. Mostly level ground on a firebreak lane makes this a moderate walk. Mosquito repellent and/or netting, sunscreen, water, and suitable clothing are suggested. Bring your lunch! We’ll picnic in the parking lot at the conclusion of the trip.
