Minn. Stat. § 561.04

Whoever without lawful authority cuts down or carries off any wood, underwood, tree, or timber, or girdles or otherwise injures any tree, timber, or shrub, on the land of another person, or in the street or highway in front of any person's house, city lot, or cultivated grounds, or on the commons or public grounds of any city or town, or in the street or highway in front thereof, is liable in a civil action to the owner of such land, or to such city or town, for treble the amount of damages which may be assessed therefor, unless upon the trial it appears that the trespass was casual or involuntary, or that the defendant had probable cause to believe that the land on which the trespass was committed was the defendant's, or that of the person in whose service or by whose direction the act was done, in which case judgment shall be given for only the single damages assessed. This section shall not authorize the recovery of more than the just value of timber taken from uncultivated woodland for the repair of a public highway or bridge upon or adjoining the land.
