Uncovering population declines of Atlantic salmon on both sides of the channel

The strategy, put forward by the Catchment Based Approach’s (CaBA) Chalk Stream Restoration Working Group, sets out recommendations to protect and restore chalk streams in England. Chalk streams face a unique set of interwoven challenges including pollution, over abstraction and habitat degradation. The strategy calls for chalk streams to have enhanced status, and drive investment to prevent further escalation of pressures.
Dr. Janina Gray, Head of Science and Environmental Policy, at WildFish said: “The strategy presents a real opportunity to improve our nations chalk streams, but it is just the beginning, and the challenge is vast. For the opportunity to be realised, and to save these unique habitats for nature and wildlife, we must have an ambitious roadmap for implementation and delivery which sits alongside the strategy”.
“S&TC’s own data from the Riverfly Census highlighted that the current bar is not set high enough for chalk streams, and according to the generic Water Framework Directive classification, ‘good’ is not enough to protect the invertebrate communities which define a healthy chalk stream”.
The key recommendations in the strategy are:
Janina adds: “reducing abstraction is a critical first step in the restoration of many chalk streams, but we need to be ambitious and go further. The longer-term planning needs to support achieving zero abstraction of all chalk streams and their aquifers (or as close as technically possible). Removing the current dependence on ‘cheap’ aquifer water, will in turn reduce pressures on water quality and riverine habitats that reduced flows bring”.
Other recommendations in the report include:
Janina concludes: “we are in a biodiversity crisis, with freshwater species declining quicker than any other, and chalk streams are on the front line. We know the measures needed to improve this habitat, what we need now is political will and the resources to make it happen. What we do in the next six months will be critical in establishing if the potential promised by the strategy can start to become a reality”.

Did you know we have a freshwater habitat in England rarer than coral reefs?
A habitat almost exclusive to this count...
Over 2,000 plants and animals have been introduced to Britain from all over the world. Most are harmless, but 10-15% spread ...
