For five years Suffolk wildlife Trust has been looking after Knettishall Heath, near Thetford.
Over that time the trust has developed a relationship with the community, with volunteers and visitors working together to restore the habitat and species.
The Knettishall Fair will be held on Sunday (August 13) as a celebration for what has been achieved on the reserve.
Visitors will be able to find out the work the trust does for wildlife and that of other conservation groups, including the Exmoor Pony Society and Suffolk Bat Group.
There will be stallholders selling plants and handmade jewellery, with local craft demonstrators including leather working, spinning, dyeing and wood craft.
Refreshments will be available alongside family activities such as mini beast hunting and trails.
The event is between 11am and 4pm.
Entrance is free but car parking is £1.
