Dustin,
Pretty sure the variety I am talking about is called blue grama, although I am not a biologist. It is short, and provides little cover, especially from avian predators, which, are doing quite well here, better than at any other time in my life.
It is less useless than, say, paved highway, to pheasants on a sub-zero January day, but, far less useful than an acre of standing row crops, that bordered woody brushland, that were removed to make way for the above plantings, during the same time frame.
They do, generally, leave the cattails, which provides winter cover, if not that much to eat.

Best,
Ted
