Sir David Attenborough's film about protecting Richmond Park has won at the national Charity Film Awards.

It came first in the category for best longform film by a charity with less than £5million turnover, beating 84 competitors.

Friends of Richmond Park made the film asking visitors to "tread lightly" to minimise their impact on wildlife.

From April 2017: Sir David Attenborough’s new film about Richmond Park asks its millions of visitors to 'tread lightly'

Chairman Ron Crompton said: "As a small local charity that has never made a film before, let alone entered any awards competition, we're extremely proud and pleasantly surprised to have won our category."

The 21-minute film also won Gold in the EVCom Clarion Awards in 2017.

Mr Crompton said: "Most importantly, this will help to spread the key conservation message of the film - tread lightly in Richmond Park - designed to raise awareness that Richmond Park is a national nature reserve and a very special place for wildlife.

"The millions of visitors who enjoy the park can help us to protect this special place by following the film's helpful conservation guidelines as expressed by Sir David."
