RE: Am I wasting my time?
The old pasture is basically worthless for what you are attempting to do-you could over plant with clover or brohm grass and enhance the feeding qualities. As stated by Dan O. if you want to improve the quality you will need to reduce the hunt pressure and leave a complete safe zone no matter how much you want to do in and do hunting there. Also sounds like you need more sillohette covering. Not trees but shrubs
