Watertown’s trees face three distinct invasive pest challenges this year. One, Pear Trellis Rust, is a fungus that has been significantly disfiguring the town’s ornamental pear trees. Another, Emerald Ash Borer, is a small beetle that causes the rapid death of ash trees. The third, Spotted Lantern Fly, is an emerging survival threat to a variety of trees, especially fruit trees.
