There was an autopsy done in Kansas City, Missouri by their local Parks and Recreation department to find out why many ash trees have been dying. Since 2002 emerald ash borers (EAB) have been eating and subsequently killing ash trees. An ash borer looks like a small green beetle about ½ inch long. When the emerald ash borer is fully grown it is still smaller than a penny. The ash borers are an invasive species originating in Asia and originally struck in Michigan. It is suspected that they had been brought to the United States on a cargo plane or ship in wooden packing materials. There is an estimated seven billion ash trees in the United States of America and they are all expected to die out within five years. Other type of trees have had damaging factors that killed a large majority of them, such as Dutch elm with the Dutch elm disease and the American chestnut with the chestnut blight, but nothing of similar magnitude of the EAB blight. The pests burrow directly under the bark, severing xylem and phloem tissue that carry water and nutrients respectively. The process of EAB killing a tree most often takes 1-2 years if it is a young tree and 3-5 years if it is a large tree. There is good news though, predators such Asian wasps and woodpeckers have been learning to eat EAB, and with the dwindling supply of ash trees to prey on, there would be no place to breed and they will die out. Action should be taken to preserve the remaining ash trees. The benefits of this is local money circulation, less fallen trees, and spending less money on removing trees. This can would be done by testing all ash trees for EAB. The trees that have been infested with EAB for over three years should be removed. If the tree has been infected for less than 3 years or not all and it still has hope to live, it should be injected with pesticide that is designed to kill borers. Injecting trees with pesticide is a much more cost effective solution than cutting down the tree. The trees that were terminally infested and have been cut down can be sold to local lumber yards to help fund the project. Once it is certain that there is no EAB in the area, treatment can stop. Blight; A plant disease, especially one caused by fungi such as mildews, rusts, and smuts.Borer;A worm, mollusk, insect, or insect larva that bores into wood, other plant material, or rock.
