The dominant features of Green’s Bluff are the steep, rugged sandstone cliffs along Raccoon Creek and the associated plant communities, including remnant groves of hemlock trees. Thick beech-maple woods grow in the rugged ravines while sycamore trees tower over the scouring rush (horsetails) which flourish along the creek.
Green’s Bluff is one of two Indiana sites where mountain spleenwort can be found. Competing for available soil and moisture in the deep shade are the large, thick leathery fronds of marginal shield fern, maidenhair fern, plantain-leaved sedge (a showy species as far as sedges go), sharp-lobed hepatica and a variety of other ferns and wildflowers. Other rare plants include hay-scented fern, goldenseal and spotted wintergreen.
Spring is a great time to view the vast array of stunning wildflowers, and the view from atop the sandstone bluff reveals a wooded landscape that feels like true wilderness.
Green’s Bluff also boasts a nesting rookery of great blue herons—tall, regal wading birds that search the waters of nearby Raccoon Creek and the larger White River further downstream for food. Close approach of their nesting colony by human intruders will be met with the loud, raucous calls of this highly gregarious species. To minimize disturbance during their nesting season, the herons should be enjoyed from a distance.
In the summer months, the wood thrush, red-eyed vireo, Acadian flycatcher, scarlet tanager and Louisiana woodthrush can also be found either nesting high in the trees or nesting in the brush. Leopard frogs, green frogs and banded water snakes are among the amphibians and reptiles found at the preserve. Various mollusks, crustaceans and fish also make their home in the meandering Raccoon Creek.
As fall approaches, the summer colors fade to red, orange and gold. Migratory birds are on the move, and you’re likely to spot several species of raptors.
When winter arrives, snow and ice blanket the area, making it a welcome respite for visitors seeking the peace and quiet of the season.
NOTE: Many of our preserves allow deer hunting from October through the first week of January, so wearing blaze orange is suggested when hiking in these areas during hunting season.
