Through research, technology, and education, the International Society of Arboriculture (ISA) promotes the professional practice of arboriculture and fosters and greater worldwide awareness of the benefits of trees.
Certified Arborist’s are individuals who have demonstrated their knowledge in the art and science of tree care through experience and by passing a comprehensive examination developed by the ISA. Certified Arborist’s must continue their education to maintain their certification and adhere to a Code of Ethics.
The Tree Care Industry Association is a 73-year-old public and professional resource on trees and arboriculture representing approximately 2,100 tree service and affiliated member companies. Our members recognize stringent performance standards for quality and safety. They maintain trained, professional arborist’s on staff and are dedicated to ethics and quality in business practices.
Emerald Ash Borer (EAB)
EAB is an insect that attacks and kills ash trees. The adulst are small, iridescent green beetles that live outside of trees during the summer months. The larvae are grub or worm-like and live underneath the bark of ash trees. Trees are killed by the tunneling of the larvae under the tree’s bark.
EAB is native to eastern Asia but was discovered in Detroit, Michigan, and Windsor, Ontario, in 2002. Indications are it may have been introduced to this area as early as 1990. EAB has been spread by ash firewood, nursery stock and possibly other ash materials to a number of new areas. EAB is in Minnesota, St. Paul Metro area, and Wisconsin.
EAB kills ash trees. All ash trees are susceptible to EAB and millions of ash trees have been killed in infested areas already. Minnesota has one of the highest volumes of ash on forestland in the U.S. with an estimated 867 million forestland ash trees and ash is a prominent component of our urban forests as well. The potential economic and environmental impact of losing these trees is substantial. The cost of removing and replacing a single tree can range from hundreds to thousands of dollars – how many ash trees are in your yard?
- Review diagnostic aids for identifying EAB symptoms.
- Look into resources on maintaining tree health.
- Consult a local tree expert such as a certified arborist or local extension person.
- Treatment should be considered primarily to prevent the infestation of healthy trees that have high personal value.
- The decision of which of the three insecticide treatments (Trunk injection, sprays, and soil applications) for treating ash use should be guided by a Certified Arborist.
