Wesselman Woods Nature Preserve is an Indiana State Nature Preserve and National Natural Landmark featuring nearly 200 acres of virgin bottomland hardwood forest. This old-growth lowland forest is of exceptionally high quality. The mean density of trees is high (125 trees per acre) and the canopy starts far above the forest floor. There are many trees reaching 100 feet tall, and some are estimated to be nearly 300 years old. The basal area of 187 square feet per acre is the highest known for any woods in Indiana.

Despite the moderate variation in elevation within the woods (only 20 ft) there is a wide diversity of tree, shrub, and wildflower species – the last survey team identified more than 125 species of plants! The degree to which sweet gum and tulip trees dominate the canopy, the large number of other trees in the canopy, combined with southern influences, set Wesselman Woods apart from other woods in Indiana. No other city in the United States with a population exceeding 100,000 has within its corporate limits, a timber stand of such acreage and sylvan qualities.

Wesselman Woods provides crucial habitat for a wide variety of animal species, including mammals, reptiles, amphibians and birds. This urban forest is abundant with raccoon and squirrel, and is often frequented by white tail deer. There are occasional sightings of fox and coyote. Efforts to protect the declining populations of rare salamanders, such as the Marbled Salamander, continue. Visitors marvel at the many woodpeckers, warblers and other songbirds that reside in or migrate through the forest. Owls and other raptors also inhabit the woods.

Historically, the Wabash-Erie Canal and 2 early railroads passed near the periphery of the preserve, but all three are now abandoned. The interior of the woods has been protected for many years. There are over six miles of walking trails within the Preserve. Other habitats include a reconstructed prairie, and a manmade and seasonal pond.

No other city in the United States with a population exceeding 100,000 has within its corporate limits a timber stand of such acreage and sylvan qualities.

A Nature Center on the western edge of the property offers hands on educational exhibits, a wildlife observation area, and gift shop. Nature Center staff provides programs to school, civic and scout groups throughout the year. Refer to our Programs section for specific opportunities. The Nature Center also offers special events throughout the year, including a Maple Sugarbush Festival in March, the Ohio Valley Birding Festival in late April-early May, and a Reptile Invasion in June.
