Whoever's been vandalizing trees in Dakota County needs to stop.
Earlier this week, Lebanon Hills Mountain Bike Trail shared a photo of a tree that has a small ring of bark removed.
Now the sheriff's office is asking people to be on the lookout for vandals.
Apparently there's a name for this practice: girdling or ring-barking. And it kills trees.
"This is a technique used in forestry, horticulture, and, in this case, vandalism, to remove an entire strip of bark from the circumference of a tree," the office posted to Facebook. "Areas above the girdle will die over time."
Authorities say several trees in the Eagan area have been girdled, and they will all probably die.
“It’s hard to know why anyone would want to kill trees deliberately in such a beautiful park,” Steve Sullivan, the county's parks director, told the Pioneer Press.
If anyone witnesses vandalism, authorities ask that you try to get a good description – vehicle and license plate, etc. – and call 911.
