The City is responsible for maintaining trees on public property (right-of-way, parks, grounds) and abatement orders for diseased trees (dutch elm, oak wilt) on private property. Residents should contact a certified arborist or forester for their private property tree concerns or issues other than suspected diseased elm, oak, or ash trees.
The City of Mounds View contains thousands of diverse trees, including mature stands of red and white oaks, hardwood maples, elms, ash, and flowering crabapple, to name a few. The Forestry Division is responsible for managing this tree stock to ensure a healthy, attractive, and safe urban forest now and for future generations. The activities of the Forestry Division are coordinated through the Public Works Department..

EMERALD ASH BORER (EAB) DISCOVERED IN MOUNDS VIEW
Emerald Ash Borer (EAB) was discovered in the City of Mounds View. The City encourages residents to look for signs of EAB. The Minnesota Department of Agriculture (MDA) confirmed an emerald ash borer (EAB) infestation in the City of Mounds View. A Mounds View resident reported an ash tree with woodpecker damage in the tree canopy, a tell-tale sign of possible EAB infestation, to the MDA for confirmation. This is the perfect time to look for woodpecker damage and other signs of emerald ash borer because the trees are still bare. There are several things residents should look for when checking for EAB. Woodpecker holes and outer bark removal are the most common visual symptoms to detect EAB, both evident on the infested ash tree in Mounds View. When the bark was pulled back, the S-shaped galleries and larvae were found in the tree, confirming the presence of the insect.
Be sure you have identified an ash tree. This is an important first step since EAB only feeds on ash trees. Ash has opposite branching – meaning branches come off the trunk directly across from each other. On older trees, the bark is in a tight, diamond-shaped pattern. Younger trees have relatively smooth bark.
Look for woodpecker damage. Woodpeckers like EAB larvae and woodpecker holes may indicate the presence of EAB.
Check for bark cracks. EAB larvae tunneling under the bark can cause the bark to split open, revealing the larval (S-shaped) tunnels underneath.
Contact a professional. If you feel your ash tree may be infested with EAB, contact a licensed tree care professional (click here for a list of licensed contractors), the City Forestry voicemail hotline, 763-717-4065, or email email@example.com, or the MDA at firstname.lastname@example.org or 888-545-6684 (voicemail).
Emerald ash borer larvae kill ash trees by tunneling under the bark and feeding on the part of the tree that moves nutrients up and down the trunk. Ash trees are often killed in about four years, although it can take as little as two years. Minnesota is highly susceptible to the destruction caused by this invasive insect. The state has approximately one billion ash trees, the most of any state in the nation.
The biggest risk of spreading EAB is people unknowingly moving firewood or other ash products harboring larvae. There are three easy steps residents can take to keep EAB from spreading:
Don’t transport firewood. Buy firewood locally from approved vendors, burn it where you buy it; and
Be aware of the quarantine restrictions. If you live in a quarantined county, be aware of the restrictions on the movement of products such as ash trees, wood chips, and firewood; and,
Watch your ash trees for infestation. If you think your ash tree is infested, go to www.mda.state.mn.us/eab and use the guide “Does my tree have emerald ash borer?”

HOT TOPIC: Is your ash tree losing leaves?
If so, it could be Anthracnose. The City has received numerous calls from residents lately suspecting their ash trees have Emerald Ash Borer but instead has turned out to be Anthracnose - a fungal disease that results in blotching, distortion, and dropping of leaves.
