John - Sounds like we have similar interests in terms of ponds that function primarily as wildlife habitat. However, I still am interested in nudging the pond in the direction I desire by stocking fish that I want and planting the plants that I want, and removing invasives. I love to see others, especially kids, catch fish in our ponds, but love the ducks, herons, and kingfishers. We have seven half grown wood ducks that are being raised in one of our shallow duck ponds which have thick reed beds for cover. I do remove the occasional muskrat though. A nudge here and there...
