But I have never encountered knee high cover that held an abundance of birds, but agree it would be the best cover for a pointer (or any other breed) to hunt and retrieve in. Here, the only grass that seems to stay knee high is brome, the native grasses that most CRP is planted to seem to be waist to head high. This year, being exceptionally dry, the switch grass was only around waist high, so it was easier to hunt this year...for the hunter and hound. Dry climates must have more of the knee high grasses, that we don't see in Iowa. As locations/climates change, the habitat changes and the methods of hunting changes. I sure wouldn't hunt knee-high brome if native stands of grass were available.
