Sedge and sphagnum moss are the primary plants here near the pond's outlet. Like the last two photos this area is like muskeg and spongy. It can potentially hold a lot of water but the water is
covered with a oily film from all the decomposition taking place in the sponge. There is very little oxygen in the water and probably subnormal amounts in the pond water it self. So this is almost the final image of the death of Zeacliff Pond although, in reality, it will be several more decades before the pond is completely transformed.
