c. Bare root stock will meet the MnDOT 3861 Plant Stock Specification available at <br /> http://www.dot.state.mn.us/pre-letting/spec/2000/sp3861.pdf <br /> d. All trees will be planted according to MnDOT 2571 Plant Installation Specification <br /> available at http://www.dot.state.mn.us/pre-letting/prov/order/2571.pdf <br /> e. After planting and up to the time of killing frost, the SWCD will maintain regular <br /> communication with staff and volunteers to ensure adequate watering of new <br /> trees. <br /> f. The SWCD may annually request sufficient funds to purchase bare root stock for <br /> spring gravel bed installation. <br /> 4. Insecticide Treatment of Trees <br /> Insecticides may be considered for ash trees that have been condition rated above 3 and <br /> that provide ecological services if EAB has been detected within a 15 mile radius. This <br /> will be allowing staff to stagger removals and reduce EAB populations— not to save <br /> trees in perpetuity. <br /> a. Large (>8" dbh) ash on public property that are a significant component of the <br /> urban infrastructure will be considered for treatment with Emamectin benzoate. <br /> Bids will be solicited to certified arborist for application to selected trees. <br /> b. Small (<8" dbh) ash on public property that are providing ecological services and <br /> are in good condition may be treated with imidacloprid by city/county staff that <br /> are licensed as chemical applicators. (Treatment for trees of less than 8"dbh <br /> should be considered carefully. The investment is not necessarily worth the <br /> return. An ash tree does not start providing ecological services at a high enough <br /> rate to pay for itself until it is 8"dbh.) <br /> Treatment will be considered for high priority trees and will not be used on hazard <br /> trees, those planted in poor locations, those that have a poor condition rating or are <br /> causing damage to infrastructure. <br /> As of 2013, the average cost for treatment: <br /> Emamectin Benzoate (TREE-age) $10 -$12/diameter inch at breast height <br /> Imidacloprid (Merit) $5 - $8/diameter inch at breast height <br /> 5. Wood Utilization <br /> Currently the City of Elk River manages a compost site that is open for public use. Similar <br /> compost sites are also located in the cities of Zimmerman, Big Lake, and Becker. Wood <br /> waste collected at these sites is contracted to be ground by a private company on an as <br /> EAB Community Preparedness& Management Plan -Page 6 <br />
