Gorgeous red Sphagnum moss and tiny, carnivorous sundews (Drosera rotundifolia) make their home in the Panthertown bog. In the southern Appalachians, which were never glaciated, bogs form where hydrology permits. These open habitats are too wet, with deep peaty soil, to support trees, but the open sunlight and consistent moisture create space for small plants. Sundews are carnivorous plants, trapping small insects on their modified leaves that have sticky glands that you can see in the picture. In this way the plants survive despite living in deep organic soils that are poor in available nutrients. Bogs are fragile places that cover very little land area–one of the reasons for the recently protected Mountain Bogs National Wildlife Refuge!
