Planet Earth reports that European lakes have become less acidic after the EU successfully tackled acid rain in the 1980s, although a complete recovery for freshwater animals and plants is ongoing. Dr Guy Woodward has been working at Lochnagar, a remote lake in the Scottish Highlands, and has found biological recovery is lagging behind. Currently there are low levels of insects and algae on the lake although he hopes that more species will come to the lake as more food is available. “As the lake becomes less and less acidic, we'll see an increase of algal production. At the top of the food web we hope to see more trout and in better shape,” he said.
