ROTHSCHILD, Wis. --- Gov. Scott Walker has signed a bill prohibiting people from bothering hunters in the Wisconsin woods.

Walker signed the bill Saturday at the Wisconsin Bear Hunters' Association's 52nd annual convention in Rothschild.

In a statement, Walker calls hunting, fishing and trapping "major pastimes" in Wisconsin, and says the bill provides hunters with "additional protections from interference."

The bill's Republican authors say concerns about hunter harassment have grown since the Wolf Patrol, a group of animal rights activists, followed and filmed wolf hunters in Wisconsin and Montana in 2014.

The bill expands the definition of interference with a hunter to include remaining in a hunter's sight and photographing or confronting a hunter more than twice with the intention to interfere.
