Clarksville, TN – Clarksville's Dunbar Cave park is collecting used Christmas trees after the holidays this year through early January. A designated drop-off pile is located in a parking lot at Dunbar and Old Dunbar Cave Roads. Park officials ask decorations be removed from any donated trees. The park plans to shred the trees for use as mulch to cover pathways, as it's a good way to control erosion without introducing seeds from invasive plants.
