Roseville, MN - Official Website - Emerald Ash BorerPage 1of 1 <br />Emerald Ash Borer <br />The Minnesota Department of Agriculture <br />(MDA) has placed a quarantine on ash <br />trees in Ramsey, Hennepin and Houston <br />counties. Emerald Ash Borers (EAB) have <br />been found in ash trees in Houston and <br />Ramsey Counties. <br />Quarantine means a person cannot <br />transport any part of an ash tree, including <br />David Cappaert, Michigan State University <br />lumber, seedlings, mulch or firewood, <br />outside of the county without permission <br />from the MDA. If you are going camping, don’t take firewood. Instead, purchase <br />firewood where you are camping and leave any wood you don’t burn. <br />EABs attack and kill ash trees. The larvae are worm-like grubs that kill the trees by <br />tunneling under the tree's bark. Adults are small, iridescent green beetles that live <br />outside of trees during the summer months. All ash trees are susceptible to EAB. <br />Minnesota has one of the highest volumes of ash on forestland in the United States. <br />Roseville estimates that about 25% of trees in the city are Ash trees. The spread of <br />EAB could have a devastating effect on Minnesota’s economy. <br />You may be approached by a firm wanting to trim or remove your ash tree. Tree <br />removal companies must be licensed by the City of Roseville. The cost of removing <br />and replacing a single tree can range from hundreds to thousands of dollars. If a <br />company offers to apply a preventative treatment to your tree, the annual cost of <br />treatment should be in the $50-100 range and the company must have a <br />commercial pesticide applicator license. Ask any contractor to show you their license <br />(s). <br />Ash wood can be taken to free Ramsey County yard waste sites. Wood dropped off <br />there is chipped and shipped to District Energy where it is burned to generate <br />heating or cooling for downtown St. Paul. Ash wood mulch is safe to use in your yard <br />if pieces are no greater than 1” on more than one side. <br />. <br />Additional information about the Emerald Ash Borer is available on the MDA website <br />http://www.cityofroseville.com/index.aspx?NID=15906/5/2009 <br /> <br />
