Threats to recovery from Scottish lake acidification

Latest report from Environmental Change Research Centre

Threats to recovery from Scottish lake acidification

Rick Battarbee, Chris Curtis and Ewan Shilland have produced a Commissioned Report for Scottish Natural Heritage on the UK Acid Waters Monitoring Network site at the Round Loch of Glenhead in Galloway, south west Scotland. Evidence from 20 years of water chemistry and biology monitoring under the UK's Acid Waters Monitoring Network, shows the loch is recovering but remains chronically acidified.

 

The recovery process is also threatened by climate change, particularly an increase in winter rainfall and sea-salt laden Atlantic storms. The long-term collaborative study, based in the UCL Environmental Change Research Centre, showed that increasing nitrate concentrations are offsetting the recovery while amounts of sulphate still remain above those that would normally be expected.

 

There are also concerns that the increasing nitrate concentrations, from air pollution and climate change effects in the catchment, may cause further damage by adding too many nutrients to the loch.
