Autumn Birch Leaves and Aquatic Sphagnum Moss

Acid lakes are widely occurring in Southern Norway. Low pH robs the aquatic ecosystem of its biological diversity and favours the expansion of acid-tolerant species, such as this Sphagnum moss. As acidification progresses, the water itself may become crystal clear. This clarity is readily apparent in my shoot here depicting fallen autumn birch leaves floating on the surface of an extremely acid bog lake in the Tovdal Valley of S Norway.
