Description: The Davidson-Arabia Mountain Nature Preserve in DeKalb County has 537 acres of natural area. Sixty percent of this unique preserve is actually a gigantic gneiss rock outcropping similar to that of Stone Mountain, its younger sibling. The Davidson-Arabia Mountain Nature Preserve also contains pine/oak thickets, an old abandoned rock quarry, and a lake. It is home to several endangered plants (including the endangered black-spored quill wort Isoletes melanospora, found in only seven other known places in the world) and is rumored to have an interesting resident salamander population. A nature center is being established on the property. Hiking is especially beautiful in autumn due to the fall color of the preserve's large forested areas.
