| White Pines in the eastern United States: Eastern White pines are found in southeastern Canada and eastern United States. In New England the pines are found in varying elevations, from sea level to 1200 meters in the Appalachians. Researchers noticed that in the high ozone months of June and July the pines began to show poor growth and the needles were dying. Researchers think that, with long-term exposure, white pines in these forests could die off. |
| Sugar Maple in the Northeast: The maples, mostly found in the Great Lake states, New England, Ontario, and Quebec have shown loss of leaves, peeling bark, and eventually, death. The decline of these trees has occurred mostly in the New England area. In Quebec, maples are dying off rapidly, and it is probably because of air pollution. |
