The Sequoyah National Wildlife Refuge in Oklahoma manages a cooperative farming program that raises wheat, corn, soybeans, and other crops on more than three thousand acres. A portion is purposely left unharvested in order to attract wildlife. (The Refuge manages 20,800 acres of habitat for wildlife.)
This year it looks like corn and soybeans. You can see in the photo that the corn is already 8 to 10 foot high at the refuge. It's a good thing they don't plant corn everywhere on the refuge because I wouldn't be able to see any wildlife if they did.
