The National Trust is to extend a popular Dorset nudist beach following successful work by wardens to tackle anti-social and indecent behaviour.
The northern section of Studland Beach dedicated to naturists will be extended 160ft (50m) inland.
The Studland Beach Users Action Group (SBUAG) was set up in 2005 to improve relations between beach users.
Allegations of indecent behaviour reported to National Trust staff have fallen from 37 in 2003 to five in 2012.
New signs will be placed on the approaches to the extended nudist area.
The length of beachfront designated for naturism remains the same and will not affect the Heather Walk footpath.
Beach operations manager Emma Wright said: "Naturists have been asking for more space for some time and we are happy to help in a way which is sensitive to the needs of all our visitors.
"We will keep the situation under review and continue to work with SBUAG and the police to ensure the beach remains a safe and welcoming environment for everyone."
Peter Thurley from British Naturism said: "Naturism is a healthy lifestyle and anyone whose behaviour drags it into disrepute doesn't get any support from us.
"Studland beach is a success story. We hope the way people work together will be a blueprint for elsewhere in the country."
