'Virtual fences' help Great Fen cows create wetland habitats
Collars with electric pulses have been placed on cows' necks to help create wetland habitats in the fens.The 'Nofence' collars are part of a conservation grazing project at the Great Fen in Cambridgeshire.The wildlife trust for the county said grazing using native breeds of cows and sheep was a vital part of managing fen grasslands, to promote wildflower growth and provide ideal habitats for butterflies, dragonflies and birds.The collars give out a short low level pulse, similar to an electric fence, with livestock quickly learning the extent of their new boundaries and to avoid approaching the "virtual fence line" again.
The Great Fen landscape project began in 2001 to connect the two national nature reserves of Woodwalton Fen and Holme Fen by restoring the surrounding land for wildlife.The Wildlife Trust for Bedfordshire, Cambridgeshire & Northamptonshire said the former agricultural land, with square, drained fields, has been turned into a natural mosaic of grass, pools and winding channels.It said static electric fences were no longer practical, so remote GPS-connected cattle collars were purchased, giving the conservation team greater flexibility over how the area is grazed.To maintain livestock welfare standards, the team also installed new cattle management areas, ditches and water supplies at New Decoy Farm, near Peterborough.Senior reserves officer David Metcalfe said: "Although it's known for its wide arable fields, the fenland landscape has been home to cows and sheep for generations. "We always knew getting grazing animals into the emerging new wild wetland areas was going to be a challenge, so the Nofence collar technology has been fantastic."The solar-powered collars are controlled via an app. Cows are alerted by an audible tone when they approach the boundary, or if they persist, they will be deterred by a weak electrical pulse.The collars can be managed remotely by the project team. The rewilding project at the Great Fen in Cambridgeshire was supported with a £78,000 grant from the FCC Communities Foundation, which awards grants for community projects through the Landfill Communities Fund.

Wildlife Trust reveals plan to revive biodiversity in the East
A conservation charity has unveiled a plan to reverse biodiversity loss over the next five years across three counties. The Wildlife Trust for Bedfordshire, Cambridgeshire and Northamptonshire aims to improve nature reserves, run education programmes and help landowners create wildlife-friendly organisation hopes to finance these efforts by raising £1.5m over the next five years, which will also fund scientific research to monitor species declines. Brian Eversham, the chief executive of the Wildlife Trust for the regions, said: "The nature of [Bedfordshire, Northamptonshire, and Cambridgeshire] is worth fighting for, and that's the ambition we have laid out in this plan." Our Wilder Future: A Plan for Nature Recovery in Beds, Cambs and Northants – 2030 includes proposals to restore habitats in the Great Fen, a 3,700 hectare peat landscape between Huntingdon and Peterborough, and teach school pupils about Luton's chalkland Eversham added: "The world has changed a lot since the start of the decade and funding the protection of nature has got a lot harder. "We could scale back our ambitions to reflect this new reality – but nature urgently needs our help so we have chosen instead to do more for nature and reach further into communities for support."According to the Wildlife Trust, there has been a 19% decline in wildlife in the UK since 1970 and nearly one in six species is threatened with extinction from Great Britain. In its plan, the Wildlife Trust has also committed to investing in more community outreach work, running education events on nature reserves and encouraging community groups to take action to protect nature.

Work begins to create new wetland at Great Fen near Ramsey
Diggers have started work on turning 25 hectares (62 acres) of land into new wetland habitat. Groundwork has begun to create a new area of wetland at the Great Fen nature reserve, in Cambridgeshire, as part of The Great Fen project. Work at New Decoy Farm, near Ramsey, will create channels that will eventually fill with water and help turn former arable fields into reedbeds, grassland and Parker, Great Fen project manager, said: "A lot of planning and preparation work has led up to this moment, so it is fantastic to see the diggers breaking ground at New Decoy for the first time." The work is part of one of the latest phases of the Great Fen vision, called the Peatland Progress, funded by the National Lottery Heritage Fund. The five-year project will see the linking of two remaining fragments of ancient fens, Woodwalton Fen and Holme Fen. The Great Fen Vision began in 2000 as the Wildlife Trust for Bedfordshire, Cambridgeshire and Northamptonshire came together with other bodies to create a 14-square mile (36 sq km) wetland landscape. Ms Parker said: "It's great timing as this spring marks 25 years since we first started out on the Great Fen journey." The new wetland will be created alongside a large winter water storage pool, ditches, and water control structures. "It will look a bit messy in the short term as we move earth about, but the vegetation will quickly grow back and there will be a newly transformed landscape where people can enjoy nature for generations to come," she added. Nearly 2,000 hectares (4,900 acres) of land is now under restoration management and work is set to begin at Speechly's Farm to continue joining the two National Nature Reserves.
