Help slow down Emerald Ash Borer

In May, the emerald ash borer was found in Saint Paul. This beetle is an invasive pest that attacks and then inevitably kills ash trees, and Minnesota and Minneapolis have a lot of ash trees to lose. Do your part this fall to slow its spread to our trees.

Emerald ash borer adults dont fly far, so they travel when people move ash logs, ash firewood or infested ash trees from nurseries. The Minnesota Department of Agriculture has issued a state quarantine on firewood, ash trees, and ash tree products in Hennepin, Ramsey and Houston counties to slow the spread of emerald ash borer to other areas.

Take steps to slow the spread of emerald ash borer within Minneapolis, within our counties and within the state:

Firewood: Buy it where you burn it. Don’t transport firewood, even within Minnesota.. In Minneapolis, you may buy bundled firewood at gas stations, which are regulated by the State. To confirm whether a fuel dealer is licensed, call 311.

Fall and winter are the seasons to trim or remove your ash tree regular yard waste pickup program, which is equipped to handle ash branches safely. Through your garbage day in the week of Nov. 16,

Start making your tree planting plans planning for your spring planting. Evergreens on the north or west will help block the coldest winter winds. Also consider variety when deciding what kind of tree to plant; while in the past the same kind of tree would have been planted extensively in an area, diversity is now preferred to avoid the kind of devastation caused by Dutch elm disease and the emerald ash borer.

Watch for signs of infestation in your ash trees. Emerald ash borer kills trees over a period of one to four years. The larvae live under the bark of the tree and feed in the tissue layer directly beneath the bark, which disrupts water from reaching all sections of the tree. This can cause a major thinning of a tree’s canopy, with as many as one-half of a tree’s branches potentially dying during the first year of infestation. The emerald ash borer has already killed more than 40 million ash trees nationwide. Minneapolis’ 200,000 ash trees make up 20 percent of all trees on public and private land in the city.If you suspect your ash tree could be infested by the emerald ash borer, visit the Minnesota Department of Agriculture website and use the "Do I Have Emerald Ash Borer?" checklist.
