Superintendent of Public Works December 10, 2010 Shade 'free Advisory Committee plan to address the Emerald Ash Borer issue Background The Emerald Ash Borer (EAB) is a small beetle from Asia that has been spreading throughout the Midwest since the mid 1990's killing the ash trees in its path - -- millions of ash trees in urban and rural settings. It was first detected in western New York State in the summer of 2009 and will gradually spread throughout the state. As of 2010 it has been positively identified in seven New York counties including Cattaraugus, Steuben, Ulster, Genesee, Monroe, Livingston and Greene. It may be only months before it will be found in Ithaca. Ithaca has 383 ash trees in the public right of way and in its parks. There are also many more uncounted ash trees in the natural areas within the city. We expect all these trees will be lost to the EAB unless the trees are treated over a ten -year period with an injectable pesticide. Otherwise the city will have to remove the trees, which as they get infested, become hazardous due to dead, falling limbs. The injection method of this pesticide recommends it over any sprays or drenches, in that there's no leaching or airborne residue. Other communities already hit by the EAB invasion have been treating their best ash trees very successfully by this method for six years. The Shade Tree Advisory Committee (STAC) is developing a plan to pro- actively manage this pest. STAC feels that the city should begin treatment of its large, historic, best ash trees, basing the selection on the following criteria: • Trees that provide a substantial function such as screening and shade • Trees that are in good health and have sound structures • Trees from all parts of the City • Trees where the site is conducive to future growth • Trees with a diversity of ages but especially large trees • Trees that may be nominated for treatment by the public Based on our computerized tree inventory, it will be possible to efficiently evaluate our ash trees for treatment. There are approximately 200 ash trees with a `good' rating. We recommend that a certified, experienced arborist be hired during the winter - spring of 2011 to perform this evaluation. It could be done for approximately $2,000. Removal Cost vs. Treatment Cost With no treatment all the ash trees will die and the city will incur a substantial cost of removing those trees, as much as $2,500 per tree for large trees in residential neighborhoods. Disposal of the wood will bring additional costs, especially for large trees, which require renting grinding equipment. Treating the trees can be done for as little as $60 per year for a 20" diameter tree. After the arborist's evaluation of trees worth saving, we will estimate the total yearly cost of treatment and return to the Board of Public Works with this information. If we treat all the trees in Ithaca that are rated `good', the cost could be as much as $7,500. Next Steps • Evaluate trees for treatment or removal on streets and in parks • Prepare public outreach education. • Work with Natural Areas Committee to address ash trees in natural areas • Treat trees • Begin removing trees and replanting Page 3 Qd it �I bA CCd CC bA it Cd I I I I I 4-o j � I � I i � I � � I � � I .
