Sheep are to be reintroduced on the '£1 a year rent' far in Conwy county, Wales.
The tenant who took over the £1m farm, 38 year old Dan Jones from Anglesey, was handed over the keys from the National Trust for the 124 acre Parc Farm in North Wales.
The site has rare habitats and species - some of which the charity said existed nowhere else on Earth.
The 360-strong flock will graze on the grassland to encourage the survival of rare plants and animals.
Sheep have not been seen on the headland since the foot and mouth crisis more than a decade ago.
Property manager William Greenwood said: "If we get this right, we should see the rarer species such as the silver studded blue butterfly and wild cotoneaster, which exist only on the Great Orme, really flourishing."
The unique £1 tenancy follows on from the announcement of the conservation charity’s new ten year vision, aimed at reversing the alarming decline in wildlife – 60 per cent in the past 50 years – and finding long term solutions to help nurse the countryside back to health and deliver for nature.
