The U.S. Forest Service says it's determined an expansion of rhododendron plants along Southern Appalachian slopes might increase the risk of landslides. Scientists at the Forest Service's Southern Research Station in Atlanta said their findings suggest the expansion of rosebay rhododendron (Rhododendron maximum) in Southern Appalachian mountain hollows may increase the likelihood of landslides during and after intense rain events. In an article recently published online in the journal Earth...
