Dying Hemlock | The Cove Forest

The hemlock wooly adelgid (HWA) is an aphid-sized insect that feeds on sap of the Canada hemlock, a widespread tree of eastern North American forests. The HWA causes Canada hemlock trees to drop their needles and eventually die. The loss of Canada hemlock tress could in turn have a negative impact on the birds and mammals that utilize Canada hemlock for winter shelter, nesting sites and food.
