Emerald Ash Borer Information

Emerald Ash Borer is an invasive insect that has killed millions of ash trees throughout parts of the U.S. and Canada.

It has been found and identified that a minimum of 20 Ash trees throughout the City of Isanti are infected and at different stages of the disease. The diseased trees are in no focused area, but spread out in different parts of the city.

All Ash trees are susceptible.

Treatment is available, if the infestation is caught early enough. Ash trees can be treated through local services or by contacting an ISA certified arborist. If the trees are not treated it is inevitable that the trees will die.

The main spread has been through the transportation of firewood. A quarantine is in place for all wood South of Highway 95 to slow the spread of the disease.

Signs to Look for on Ash trees:

Woodpecker Holes

Bark Cracks

S-Shaped Galleries

More information on Emerald Ash Borer and tree treatment can be found in packets located at City Hall.
