Plan to save British crayfish
July 21st, 2009 | by Nick |

A £210,000 breeding programme has been started to save Britain’s rare native white-clawed crayfish. The species (Austropotamobius pallipes) is in danger of being wiped out by invasive American signal crayfish, which carry a disease, crayfish plague, which is fatal to the British species. The crayfish are being bred at secret locations in the south-west of England. American crayfish were introduced in the UK twenty years ago for farming. This has since led to the disappearance of almost 95% of the native species, which faces extinction from UK waters within 30 years unless new populations can be created in safe, uncontaminated waters.

The oldest osprey of the UK – and probably the world – has returned to her eyrie in the Scottish highlands. When she left for West Africa at the end of last summer, no one expected her to return. At 26 she’s lived 3 times longer than most female ospreys. In her life she’s laid 58 eggs and hatched 48 chicks, a massive individual contribution to the survival of ospreys in Scotland, where there are still only about 200 breeding pairs. The questions now are if her mate will return and if she is still fertile. Events can be followed on the 
Otters, water voles and fish are all benefitting from the improved quality of the UK’s waterways, now described as the cleanest since the industrial revolution. Since almost disappearing from the wild in the 1970s, otters are thriving, particularly in the south west of England, Cumbria and Northumberland. The population of water voles, highly precarious in the 1990s, is also beginning to recover. The good results of stricter pollution controls and extensive conservation work are set to continue in the new year with the introduction of new European water quality directives.
