Currently there <br />have not been any confirmed cases in Roseville, but there have been cases in St. <br />Anthony Park, a neighborhood of St. Paul. Staff is continuing to work with and gather <br />information and recommendations from State Departments and other agencies. All <br />indications are that we will be faced with this potential devastation sometime in the near <br />future. Now is the time for awareness and planning. At this point, it is important that <br />Roseville develop a strategy to minimize the EAB impact as well as improve our current <br />urban forest. Currently, concentrated efforts are on the following areas: <br />1) Tree inventory update as resources allow <br />• Knowledgeable volunteers are physically canvassing the City <br />utilizing two notebook computers <br />20 • The inventory will focus on all public trees (primarily street trees) <br />21 as well as the associated costs for removal and replacement (it is <br />22 anticipated that approximately 25% of the trees in Roseville are <br />23 Ash variety) <br />24 • The inventory is anticipated to be completed by mid to late <br />25 summer 2010 <br />26 <br />27 <br />28 <br />29 <br />30 <br />31 <br />32 <br />33 <br />34 <br />35 <br />36 <br />2) Improving detection skills <br />• Emerald Ash Borer is very difficult and almost impossible to <br />detect, staff is becoming more familiar with the pest and learning <br />proper detection techniques <br />3) Communication of Quarantine <br />• Currently there is a quarantine in effect for three counties in <br />Minnesota, i.e. Hennepin, Houston, Ramsey Counties. This <br />quarantine restricts the transportation of wood from deciduous <br />trees in and out of the affected counties. <br />
