Ripples on the River

Ripples of excitement are spreading through Europe's rivers and wetlands. A generation ago, otter watching was a wildlife highlight restricted to remote coastal areas - otter populations had been decimated over the previous century by pesticide poisoning and habitat disturbance. Now we are seeing the positive effect of determined conservation efforts over recent decades. As our waterways improve, otters are returning and spreading throughout their former habitats. One of the UK's leading natural history photographers, Laurie Campbell got to know otters while working in Scotland's Highlands and Islands, but he had never seen these elusive predators on his home beat. Then, in the early 1990s, he was delighted to find otters back on the Tweed and its tributaries, a river system he has lived close to for most of his life. The discovery launched him on a quest to create a photographic account of their lives on his home river.
