SAVE THE HEMLOCKS T-SHIRT LONG SLEEVE--Hemlocks in the southern Appalachians are under attack from a non-native insect, the hemlock wooly adelgid. If nothing is done, we will lose these magnificent trees, including the thousands of acres of old-growth in the Smokies. Will the hemlock go the way of the American chestnut and Fraser fir? Not on our watch! At least $9.45 from your puchase of this beautiful shirt will go to save hemlock trees in the Smokies. The purchase of one shirt will generate enough income to treat a 75-foot tree or raise about a dozen predator beetles. Predator beetles eat lots and lots of hemlock adelgids, and they breed like crazy, too. 100% cotton, Available in natural.
