Planting cover/food source for wildlife such as switch-grass can be very beneficial . Especially where clearings exist in large mature woods with very little natural cover.
So many times people put out feeders etc. when their wooded property is surrounded by acres of soybean,corn etc. farmers plant. Hard to compete with that using a feeder. Creating thick cover close to these farm fields for the wildlife and hunter(
) works wonders in this scenario.
