Predator beetle released to combat woolly adelgid on Signal Mountain
(Nov. 21, 2014) - "Save the Hemlocks" was established on Signal Mountain more than a year a half ago when residents noticed some of their trees were dying. Barbara Womack, Vice Chair Signal Mountain Tree Board said, "It looked like snow on the trees. It was just coated with white woolly egg cases. And we decided, 'oh something needs to be done.'" The white woolly substance on the trees turned out to be the woolly adelgid, so the Signal Mountain tree board and residents created a project that would release 1-thousand beetles at Rainbow Lake Trails to combat the small insect. The project is supported by donations and represents the first of its kind by a non governmental agency in the state.
