It takes a while, of course, and the first years of a pond can be very picturesque, after the initial scouring of the edges is masked by emergent vegetation. Once a sizeable invertebrate fauna becomes established, perhaps augmented by the arrival of sticklebacks or other fish via the storm system or other means, larger animals appear: waterfowl, herons, raccoons, etc.But such paradises must be managed closely in urban settings. The filling in of a pond can be remarkably fast because of the amount of debris that decends onto the surface during winter months. Some may be windthrow from winter storms, but there is another kind of throw, anthropothrow.
Why does this happen?
Because we want to break the ice!
Even complete automobile wheels won’t do it. Anybody know where we can get an anvil? A safe?
