Here is an excerpt from the winter newsletter from the Stanley M. Rowe Arboretum in Indian Hill, Cincinnati.  The arboretum is within two miles of an identified Emerald Ash Borer infested area.

Back Tree Service, Cincinnati, used their Pneumatic Vertical Mulching tool to promote soil remediation, and then applied liquid fertilizer as the first phase of promoting tree health.  The second phase in Back Tree’s guaranteed system is to inject the trees with TREE-age using the ArborJet tree injection system.

Ohio Department of Agriculture Expands Emerald Ash Borer Quarantine

Department adds 14 counties to existing quarantine

REYNOLDSBURG, Ohio (Jan. 14, 2010) – Ohio’s Emerald Ash Borer quarantine was expanded today by the Ohio Department of Agriculture to include 14 additional counties. The quarantine helps slow the spread of the ash tree-killing insect to uninfested parts of the state by prohibiting the movement of all hardwood firewood and ash tree materials.

While the invasive pest has not been detected in the following 14 counties, the department issues this quarantine to make the movement of ash trees, parts of ash trees and all hardwood firewood more practical among counties that are adjacent to previously quarantined areas. The following counties are now on the quarantine list: Adams, Ashtabula, Brown, Clinton, Coshocton, Fayette, Geauga, Highland, Holmes, Knox, Lake, Madison, Ross and Trumbull.

Since Emerald Ash Borer was first discovered in Ohio in 2003, the department has placed 67 counties under quarantine. The quarantine makes it illegal to transport ash trees, parts of ash trees and all hardwood firewood from any quarantined county into or through a non-quarantined county without a compliance agreement from the Ohio Department of Agriculture. Violation of this quarantine could result in fines up to $4,000. A federal quarantine makes it illegal to take these items out of the state of Ohio.

Firewood dealers, businesses or woodlot owners interested in marketing and transporting ash trees or firewood from quarantined areas can do so only with a department-approved compliance agreement.  These agreements define handling practices that reduce the artificial spread of Emerald Ash Borer.

Ash trees infested with Emerald Ash Borer typically die within five years. The pest belongs to a group of metallic wood-boring beetles. Adults are dark green, one-half inch in length, one-eighth inch wide, and fly from early May until September. Larvae spend the rest of the year beneath the bark of ash trees and leave D-shaped holes in the bark about one-eighth inch wide when they emerge as adults.

Suspected Emerald Ash Borer adults and larva can be confirmed by sending the suspected specimen(s) to the Ohio Department of Agriculture for identification using the form located on the department’s Web site. Visit www.agri.ohio.gov and click on “Emerald Ash Borer Program” located under the “Regulatory Programs” tab. The form is available by clicking “Submit a Sample” on the left-hand side.

Here is Tim’s response to a recent article on the Emerald Ash Borer in the Greater Cincinnati tree service area.

“Elm trees were lost to Dutch Elm Disease and replaced mostly with Ash trees. Today Dutch Elm Disease is treatable – it took decades to get the right treatment and the right delivery system.

Today we have Ash trees threatened by the Emerald Ash Borer which was discovered in the Tri-State area in 2006 and is only just becoming a major local threat.

The big difference between Elm tree problems and the current Emerald Ash Borer problem is that technology was too slow to save Elm trees. But today we have proven technology to successfully treat Ash trees, so why don’t we use it?

Will the tree replacement for Ash trees succumb to a different insect or disease and require removal again?

The next major threat is the Asian Long Horned Beetle.  It chooses about 15 tree species and mainly targets Oaks and Maples.

Euthanasia by chain saw is not the answer. It only gets repeated. Treating trees saves money over removal, upon removal, upon removal.”

This piece on the Emerald Ash Borer was exerpted from an article in the Cincinnati Enquirer that covered a number of ecological threats from invasive species.

The key point is that removal and replacement of Ash trees would cost between $1 billion and $4.2 billion.

There are alternatives to removal and replacement if action is taken early enough to protect trees against the Emerald Ash Borer.  Since the discovery of the Emerald Ash Borer in the Cincinnati area, Back Tree Service has worked on a cost effective solution to the EAB.
