Overbridge Class II Natural-Scientific State Natural Area

Overbridge is a 70-acre natural area located in Rutherford County approximately eight miles east of Murfreesboro. It supports a globally rare Middle Tennessee cedar glade ecosystem that provides habitat for six state listed plant species, as well as, leafy prairie clover (Dalea foliosa) and Pyne's ground plum (Astragalus bibullatus), which are both federally endangered plant species.

The natural area has a small stream running through it called Dry Creek. The east section of the property contains most of the cedar glade with some barrens occurring where deeper soils support perennial grasses like little bluestem and side oats grama. Both the cedar glades and the barrens are surrounded by patches of eastern red cedar and mixed hardwoods which include several oak species like chinkapin, post, and Shumard's along with blue ash, winged elm, and southern shagbark hickory. These are typical tree species associated with cedar glades, and they are usually stunted due to shallow soil conditions and drought conditions that maintain the openness of the glades.

A few small farms and single-family residences surround the natural area. It had once been part of a 260-acre farm owned by Overbridge Cattle Company and it was purchased by the State during foreclosure procedures in 1993. The Nature Conservancy of Tennessee has also been active here, and has assisted in protecting Pyne's ground plum by fencing the area. Management needs require control of invasive species such as common privet, Queen Ann's lace, and common teasel. Common privet is a serious problem affecting much of the west section of the natural area.
