Trespass law modification to allow purple markings provision

SF 1875 modifies Minnesota's trespass law to allow landowners to use purple paint marks instead of posted signs to prohibit outdoor recreation on their property. Landowners (both private and public) who wish to restrict access can now place vertical purple marks on trees or permanent objects meeting specific size (8 inches long, 1 inch wide) and placement (3-5 feet high, 100 feet apart on forest land) requirements. This change adds purple markings as a legally recognized alternative to traditional "no trespassing" signs under Minnesota Statutes section 97B.001. The bill does not create new restrictions but provides an additional, standardized method for landowners to communicate access rules.
