After being absent from its former habitat for more than 70 years, a protected species of butterfly has been reintroduced.
According to a natural history group, heathland conversion for forestry and housing has resulted in the loss of silver-studded blue butterflies from more than 80% of their former habitats over the past century.
Only four locations in Norfolk are currently home to them.
The group has moved 35 of the scarce butterflies from Buxton Heath to a country park near Horsford.
The site at Broadland Country Park was the original source of butterflies introduced to Horsford Rifle Range, Buxton Heath and Kelling Heath, but the original population was destroyed in the 1950s when plantation forestry took over.
The Norfolk and Norwich Naturalists' Society stated that the species should once again thrive in its former home now that the trees have been removed. Heather and black ants, which the butterflies need to complete their life cycle, have also returned.
Broadland District Council established monitoring at the park, and it will continue for at least five years.
Alan Dawson, who monitors the silver-studded blue at Buxton Heath for Butterfly Conservation, said: "The butterfly has done very well indeed here, and it was time to take some individuals back to their restored home. ".
Volunteer Dave Weaver added: "The return of the iconic silver-studded blue to its former home is a moment of great pride to us all. ".
