Worth Preserve, a unique natural area, is a mosaic of a floodplain, hardwood forest, pine plantation, managed prairie, and thickets. Trails through these varied habitats will lead you to the eastern border of the park, a stretch of scenic Greenville Creek that remains in its natural state, having never been dredged or channelized.

The meandering stream and diverse flora and fauna make Worth Family Nature Preserve an exceptional natural area to visit any time of year. The trailhead begins at the restored prairie. Indian Grass towers overhead, but you can still catch a glimpse of Tree Swallows darting and swooping to and from their nest boxes in the spring and summer months. Watch for Monarch and Red Admiral butterflies crossing your path in search of nectar sources. The prairie gives way to a dense stand of 35-year-old White Pine trees. This quiet, sheltered place is an ideal roosting area for Wild Turkeys and Great Horned Owls, who hide within the drooping boughs and branches. Continue through the muffled quiet of the pines and enter a noisy thicket of wild Hawthorn and Crab Apple trees. The abundant fruits and seeds provided by these trees keep many animals active well into the winter months. A variety of bird species nest in this intermediate succession area, attracted by the protective thorns and ample food supply.
