The farmers do not care about leaving food for wildlife. The only reason they leave any standing is because they are required by contract to leave a certain percentage of the crop stand for wildlife. They do not harvest it, they are not allowed to harvest it as it is part of their payment for planting on game lands. If you would like the standing crops to be left standing in a different place the PGC would have to write that into the contract. However, it is better for wildlife if the standing crop is further away from the edge of the fields because the edges are where most of the deer, raccoon and squirrel damage happens so there is more food left in the middle than the edges after the harvest. It is no great feat for wildlife to walk to the center of a field to eat or seek shelter.
When you are up to your butt in alligators, it is hard to remember your intent was to drain the swamp. Stay focused!
