The area contains a diversity of habitats, including old fields, stands of hemlock, white pine, and hardwoods, a 2-acre gum swamp, and a 45-acre marsh. A portion of Mud Pond is within the property along with several beaver ponds. The topography is generally rolling and rocky. Remnants of woodcock and ruffed grouse habitat demonstration plots from the late 1970s can still be found in the northwest section of the WMA, along with more recent habitat management to maintain fields and early successional habitats.

Leonard WMA is accessed off Couchtown Road via South Road through the Blackwater Flood Control Area. There is room to park 1-2 vehicles at the gate. Knights Meadow Marsh can be reached from the Knights Meadow access road off of White Plains Road. There is a gravel boat launch and parking for 2-3 vehicles at the dam.
