North East 바카라 사이트˜Ark바카라 사이트™ sites are safe haven for endangered crayfish
The Environment Agency and Northumberland Rivers Trust have relocated hundreds of native crayfish to six refuge sites in North Northumberland.

The Environment Agency and Northumberland Rivers Trust have relocated hundreds of native crayfish from the abundant populations found in the River Wansbeck in Morpeth, to six refuge sites in North Northumberland.
These refuges, known as 바카라 사이트˜Ark바카라 사이트™ sites, give the crayfish new safe places to breed and build their numbers, ensuring several populations remain if disaster strikes on the main Wansbeck.
The River Wansbeck is one of the last remaining strongholds for the white-clawed crayfish, but the survival of the species is threatened by the invasive and highly aggressive American signal crayfish. Signal crayfish are bigger, outcompete for food and can pass on the 바카라 사이트˜crayfish plague바카라 사이트™ which is deadly to the native crayfish.
The signal crayfish, which originates from America, was introduced in the 1970s and can also burrow into banksides, causing increased siltation of watercourses.
Crayfish relocated during maintenance work
Over the last few weeks, native crayfish have been moved from the main River Wansbeck at Mitford and relocated to the Ark sites. The opportunity to move a large number of the crayfish has come as a result of maintenance works being carried out at Mitford Dam, which is part of the Morpeth Flood Alleviation Scheme.
The crayfish were collected by experienced and licenced staff using a combination of traps, stone turning and hand nets, all under a Natural England conservation licence.
It바카라 사이트™s just one part of the wider Northumberland Crayfish Strategy, which also involves partners including the National Trust and Northumberland Zoo, to ensure 2022 isn바카라 사이트™t the native species바카라 사이트™ final year in the county바카라 사이트™s rivers.
바카라 사이트˜Very real danger바카라 사이트™ of native species disappearing from rivers
The Environment Agency바카라 사이트™s Ian Marshall, Biodiversity Technical Specialist in the North East and white-clawed crayfish National Species Lead, said:
We바카라 사이트™re in very real danger of this native species disappearing from our rivers. These new Ark sites will give them a chance to breed and build new populations to help secure their long-term future.
It builds on the positive progress already made by ourselves and our partners in Northumberland to protect them.
Pete Kerr, Northumberland Rivers Trust, said:
While Northumberland바카라 사이트™s rivers do have some of the best remaining populations of native crayfish in the UK, the invasive signal crayfish are a constant and imminent threat.
Many people haven바카라 사이트™t seen a native crayfish but they are amazing creates that play a vital ecological role. We need to do all we can to shelter them from harm and these new Ark sites will play a key role.
The Northumberland Crayfish Partnership is calling on people to 바카라 사이트˜Check, Clean, Dry바카라 사이트™ their clothing and equipment after visiting local rivers to avoid transferring invasive crayfish and the crayfish plague between rivers which can be transported in damp soles of shoes or within fishing gear.
If you see any crayfish, alive or dead, leave it where it is and report it immediately to the Environment Agency on 0800 80 70 60. If possible, take close-up photos of the crayfish to help identify the species. It is illegal to handle or remove crayfish from the water without the correct licences.
