Breeding groups of wild horses have been re-introduced to a nature reserve in Cambs after a 4,000 year absence.
The last herds roamed the area of Wicken Fen thousands of years ago, wardens said on Tuesday.
A herd of konik ponies - a primitive Polish breed - was brought to the fen to help manage it in a sustainable way.
The fen has been home to the breed since 2001, but the first breeding herd came in 2003. After two years, they have produced their first offspring.
Four male foals have been born this spring, increasing the herd to 29.
Wicken Fen is one of Britain's oldest nature reserves and has been managed by the National Trust since 1899.
