ST. PAUL, Minn. (AP) - The Minnesota Department of Agriculture says it's discovered another infestation of the destructive emerald ash borer.
This time it's been found on private land near Caledonia in southeastern Minnesota.
Agriculture officials say the spot in a grove of trees in a cattle pasture is about 10 miles from previously known infestations in Houston County, but still within the quarantine area.
Other counties included in the quarantine are Hennepin, Ramsey and Winona. The quarantine is in place to help prevent EAB from spreading outside the area by restricting movement of firewood and other materials from ash trees that might have the ash borer's larvae.
Since the pest was first discovered in North America, it has killed tens of millions of ash trees in 18 states.
