[2][3] Revis Hill is managed as a fragile ecosystem of loess, a loose, powdered loamy soil type formed from silt ground fine by glaciation and other events.

Land management practices utilized at Revis Hill include prescribed burning and the control of invasive species.

[2] Tallgrass prairie plants, such as little bluestem grass, purple coneflower, and leadplant countered the erosion by developing significant, interlaced root systems that held much of the loessy dust in place in the uplands.

Rare plants such as Skinner's gerardia and jeweled shooting star (Dodecatheon amethystinum) can be found at Revis Hill.

The Illinois Nature Preserves Commission advises visitors to be on the lookout for bluebirds, western hognose snakes, and prairie walking stick insects.
