Tree rings from a short-leaf pine tree are displayed this month in Lynn Hollow in the Great Smoky Mountains National Park. The rings show fires scars thoughout the tree's life until 1932, when fires stopped due to the Park Service's fire suppression policy. The Park Service is planning a prescribed burn this year to increase the number of short-leaf pines and boost species diversity.
