Campaigners are calling for more action to help wildlife in the Broads following a new ‘health check’ of the wetlands.

A quarter of Britain’s threatened species can be found in Norfolk’s waterways, making it the most biodiverse wetland in the country.

But a report by the Campaign for National Parks has shown that the condition of some of the habitats they live in are in decline and just 7pc of the rivers and lakes that make up the Broads are categorised as “good”.
