The organisation that manages the Broads National Park has warned that urgent action is needed to protect wildlife from the impact of climate change and pollution.

Declaring a biodiversity emergency, the Broads Authority said the area of open water and rivers in Norfolk and Suffolk had been losing species at a rate of six per decade in the past 50 years.

It said it wanted to raise public and political awareness and “foster stronger partnerships” on critical issues, because “time is running out”.
