Great Orme, Conwy

Surrounded on three sides by the sea and bathed in sunshine, the Great Orme has an exceptionally mild climate which, combined with the lime-rich rock, make it one of the top five sites for rare plants in Britain.

An unprecedented number of native wild flowers – 360 species in all – grow here and nearly 20 of these are nationally rare and threatened, including the Great Orme Berry (Cotoneaster cambricus) that occurs nowhere else in the world. There’s an abundance of rare lichens and mosses too, all of which mean the Great Orme is recognised internationally as an Important Plant Area. This diversity supports a host of other wildlife, such as unique subspecies of silver-studded blue and grayling butterflies, as well birds such as chough.

But in 2001, following the foot and mouth outbreak, sheep were restricted to small enclosed areas of farmland and grazing over the Orme’s wilder unenclosed landscape has declined. As a result large areas became dominated by thick grass and shrubs such as blackthorn and invasive non-native cotoneaster. Without action, this undergrazing would have threatened many of the Orme’s special flowers.

In 2016, the National Trust purchased Parc Farm on the summit of the Orme, and with it the grazing rights to nearly 300 hectares of the surrounding wild landscape. Plantlife purchased a flock of over 400 sheep for the Trust’s new shepherd to target grazing in priority areas.

Our goals:

  • Restore limestone grassland habitat by controlling the growth of vigorous grasses and scrub
  • Help control the spread of invasive non-native Cotoneasters with increased grazing
  • Allow the special flowers and invertebrates found on the Great Orme to flourish again.

What are we saving?


Hoary rock-rose (Helianthemum oelandicum subsp. incanum)

This little rockrose, which produces carpets of tiny flowers in late spring above mats of silvery foliage, grows in just a handful of sites in Wales. Its diminutive size makes it vulnerable to undergrazing and the encroachment of vigorous grass. In many places on the Great Orme, it is now confined to the rockiest ledges where the grass is thin.


Great Orme Berry (Cotoneaster cambricus)

Our only native cotoneaster, there are just six original wild bushes of this little gem left in the world. Many other plants have been raised from seed and cuttings and some of these are planted out on the Orme to bolster the population (if you want to see it, there is one in the wildflower garden at the visitor centre on the summit). This species is vulnerable to grazing from a feral population of Kashmir goats and from invasive non-native cotoneasters, which get a foothold in the same little pockets of soil on the limestone cliffs.


Basil Thyme (Clinopodium acinos)

The beautiful purple-blue flowers of this little annual plant are produced throughout the summer. In Wales, it grows only on the Great Orme and several places on the south coast, such as the Gower peninsula. It grows on lime-rich soil in open places where its seeds can germinate and it cannot tolerate competition from dense grass.

How's it going?


July: Thanks to the grazing, wildflowers are blooming.

Watch Plantlife's Trevor Dines and Dan Jones as they reveal the importance of the Great Orme for wild plants and the how the grazing is needed to conserve them (video in Welsh and English).


October: the first 295 Lleyn sheep – a native breed from the nearby Lleyn peninsula - arrive on the Great Orme (photo © Richard Williams). They will soon be joined by a small number of Herdwick sheep

September: Dan and Colin Cheesman (Head of Plantlife Cymru) scour the autumn livestock markets to buy a flock of over 400 sheep, purchased wholly with the support of Plantlife members.

August: Shepherd Dan Jones is granted the "£1 a year tenancy" of Parc Farm, beating competitors from as far afield as New Zealand and the USA.

Meet Dan the shepherd:


Parc Farm, a small productive farm on the summit of the Great Orme, comes up for sale in March along with grazing rights to 292 hectares of the surrounding unenclosed landscape, where all of the wildflower interest is found. With advice from Plantlife, the National Trust purchase the farm and in September form a partnership with ourselves and other organisations to help manage the Great Orme.
