An Oxfordshire wildlife trust has joined a group of charities in calling for action to protect the UK’s chalk streams.

The Berkshire, Buckinghamshire and Oxfordshire Wildlife Trust has joined the group of nature charities in urging the government to safeguard these rare habitats in planning reforms.

Chalk streams are characterised by their clear waters and diverse wildlife, with 85 per cent of the world's chalk streams found in England, including Letcombe Brook and Chalgrove Brook in Oxfordshire.

However, out of more than 220 habitats, only 11 have legal protections.

Conservationists argue these measures are insufficient to protect chalk streams from indirect pressures such as pollution elsewhere in a river’s catchment, or abstraction to supply water for new housing.

Estelle Bailey, chief executive of Berkshire, Buckinghamshire and Oxfordshire Wildlife Trust, said: "Our chalk streams should be sparkling crystal clear and bursting with life.

"As one of the rarest habitats in the world they should be the crown jewel of our natural environment but like all our rivers they have been let down.

There is currently no formal plan to protect or restore English chalk streams, with the fate of a 'Recovery Pack’ which was in development under the prior government currently unclear.

A letter to Angela Rayner MP and Steve Reed MP, which calls for proper protections, is headed by the Wildlife Trusts and signed by various river, water, and wildlife charities including The Rivers Trust, Angling Trust, River Action, and Wild Trout Trust.

It follows the March for Clean Water, which saw more than 15,000 people, including charities, campaigners, and celebrities, gathered in London calling for the government action to improve the health of rivers, lakes, and seas.

Steve Backshall, wildlife presenter and president of the Berkshire, Buckinghamshire and Oxfordshire Wildlife Trust, said: "Chalk streams are our equivalent of the Amazon Rainforest, home to everything from kingfishers to salmon and water voles.

"They need us, they need our efforts, and they need proper rules in place to protect them."
