  1. Our first wind farm analysis suggested that turbines be place no closer than 1/4 to 4.5 miles from the actual shoreline along Saginaw Bay in Michigan. Turbines placed at 4.5 miles or further from the bay have caused no swan mortality to date to our knowledge. Considering that we predicted 1 to 2 mortaities per year at this distance (having determined that to an estimate on the high side–e.g. no more than that number of swans) we are somewhat pleased. Turbines closer to the Bay near Pigeon Michigan have not been in place long enough to get a good statistical sample, However, we welcome the data. Similarly, in our surveys, both with restidents, wildlife experts, and our own surveys, we rarely found swans inland more than a mile from the shoreline, suggesting that there is little habitat impact. Place with some care, we do not anticipate population level impacts from wind turbines near Saginaw Bay. Caitlin Coberly, Principal Ecologist, Merlin Ecological.
