MDA survey finds 59 St. Paul trees infested with emerald ash borer
A multi-agency survey found 59 trees infested with emerald ash borer in and around the St. Anthony Park neighborhood where the pest was first discovered in May. All 59 trees are within a half mile of the first infestation site. Crews have already removed the 59 trees. Read the June 2009 news release.
Monitoring efforts using purple cardboard traps and “trap trees” is underway.
Homeowners are asked to join the effort by watching their ash trees for signs of infestation. These signs include:
- dieback of leaves in the upper third of the tree’s branches
- heavy woodpecker activity
- D-shaped exit holes in the bark
- S-shaped tunnels under the bark
- water shoots on the trunk

Minnesota Department of Agriculture Quarantine
On May 15th, 2009 the quarantine (previously applied to Houston) added Ramsey and Hennepin counties to prevent the spread of Emerald Ash Borer to new areas through the movement of infested wood and tree parts. Besides applying to all ash tree parts, the regulations apply to all non-coniferous firewood. Read more about the quarantine(pdf).
Don’t remove your healthy ash trees
MDA reminds homeowners that it is not necessary to remove healthy ash trees. Homeowners with questions about disposing of ash tree material should contact their city forester for guidance. Improper disposal of infested ash material could accelerate the spread of EAB.
What does EAB mean for the woodland owner?
Update: There are a few useful resources for woodland owners concerned about EAB. Check out our video and links on EAB and your Minnesota woodlands. Michigan State University Extension also has a helpful publication to help woodland owners prepare for EAB.
