EAB & NATURAL RESOURCES
EMERALD ASH BORER IN CHANHASSEN The Minnesota Department of Agriculture has designated Carver County as a "generally infested area." This designation carries several management implications: removing infested trees is no longer an effective control strategy, infested ash trees in undeveloped areas are typically left standing to provide wildlife habitat and the only viable option for preserving ash trees in good condition is through treatment. If ash trees must be removed, the wood cannot be transported from Carver County to a non-quarantined county.

What’s the city doing with ash trees? Over 7,000 trees are inventoried on city streets and parks. Of those, roughly 15% are ash trees. The city selected about 600 ash trees in these areas that are on a bi-annual treatment schedule (about 300 ash trees are treated per year). They’re inspected before each treatment cycle by the contractor to make sure the trees are still good candidates for treatment. This has allowed the city to preserve high value ash trees as EAB makes its way through Chanhassen. Trees that don’t pose a public safety risk in undeveloped areas are left standing and are considered beneficial to wildlife.
My neighbor’s tree hangs over my property... what can I do? In Minnesota, property owners have the right to exercise “self- help,” which allows you to trim branches that extend over your property line. However, this right comes with limits: the trimming must not kill the tree or significantly harm the overall health of the tree. For example, removing too much of the canopy or pruning an oak during the growing season—when it becomes vulnerable to oak wilt—would be considered harmful. If you’re unsure about what will harm the health of the tree, consult with a tree care professional before cutting. It’s also always recommended to talk to your neighbor before doing the work.
