Quail as we have found out all over the country are a finite resource that can't take a great deal of pressure. Snow or any other factor that in combination creates stress isn't good. Long periods of snow pack, like 10 days in a row compounds the problem. If they have hard woody cover and weed seeds, sumac, they get by. Managing wild quail successfully is vastly more difficult than pheasants, requires careful harvest management, specific habitat requirements, last but not least good and lucky weather. Makes me want to cry when I think how we were lucky enough to have the perfect storm of circustances to produce armies of quail, 40 years ago, and all by accident! Now we fight for a few coveys here and there.
