Steven Seagal has finally run into a foe that is too much to handle.

Comment on this story

The action-movie actor has decided to sell his 19,000-acre Montana ranch rather than fight the knapweed that is overrunning the property and threatening native grasses."Mr. Seagal was very unwilling to deal with the knapweed problem four years ago when he purchased the property," said David Schulz, director of the Madison County Weed Control Board. "He just didn't consider the weed a priority."

The ranch along the Madison River is an important piece of the ecosystem surrounding Yellowstone National Park.
