To the left is a section of the Chase Lake National Wildlife Refuge near Woodworth, N.D.. This section, which refuge manager Neil Shook describes as "a weedy mess," hasn't been grazed in decades. To the right is a section of the refuge being grazed by sheep this year; the sheep have eaten many of the weeds.
