Oak Knoll is a small hill just east of Razorback Road, south of Cato Springs Road and north of the Fulbright Expressway.
It contains remnants of oak savanna on the hill but also tallgrass prairie, forested and open wetlands, dry upland woodlands, and the relatively large Cato Springs Creek, which wraps around it all on the northern and eastern sides.
In 2023, Andrew Ruegsegger, a student at the University of Arkansas, made a detailed inventory of the botany of the knoll and surrounding terrain.
The property is owned by the University of Arkansas.
