You may be noticing leaves of various hardwood trees already turning to fall color in lowland areas. These lowland areas are holding more water this year and it is affecting the trees. The trees in these areas are stressed from being in water too long, and this is causing the hardwoods leaves to turn color early. Some of the hardwoods are dying in these lowland areas, and most conifers in these areas are also dying due to too much water.
