Gentleman, I have heard this all before. The diversity mantra almost sunk our wild pheasant reintroduction program. While the idea of diversity is absolutely correct, it's application is flawed when it comes to winter cover and nesting cover. Also, using it in the east is much different than using it in the western prairie states. Here in the east, our landscape is fragmented into smaller fields. We have landscape diversity through fragmentation. You only need to go a couple hundred yards to find the food and other needs the pheasant requires. Our diverse plantings of big bluestem and Indiangrass are useless for winter cover as they lodge terribly and provide no winter cover. Switchgrass has saved the day and only by accident. Against the local biologists recommendation, we had one farmer plant a 40 acre field with 10 lb/acre switchgrass. The population of birds here is fantastic. We are past theory on this idea, we have the numbers to show it. I have been accused of wanting to plant nothing but switchgrass. The reason why I want to do that is because we in such short supply of good winter and nesting cover. If our CREP acres were 50% primarlily switchgrass, we would have a pheasant explosion here. I am not recommending planting a quarter in the Midwest with swtichgrass. That does create a monoculture situation. Planting 50 or 75 acres of the quarter would be a great idea. There must be some agriculture or food plots nearby to provide food, but you would notice the difference. I have only ever seen one switchgrass field that was too dense to provide cover. It had been planted at 20 lbs/acre by mistake. A dog couldn't even get through it. We have found that at 8 to 10 lbs, there is plenty of open spaces for movement.
