Moelyci Environmental Centre was established in 2003 by a group of enterprising local people aiming to conserve and manage its rich natural heritage. The area possesses a remarkable range of habitats from the mountainous wind-swept heath land down to lowland pasture, marshes, streams, flower-rich meadows and woodland.
The acid heathland of the mountain, perhaps the best in North Wales, boasts a beautiful expanse of Heather, Bilberry and Gorse of such high value that it is now part of the Eryri Site of Special Scientific Interest (SSSI). Red Grouse, Stonechat, Raven and Chough are seen regularly, along with a variety of birds of prey. Throughout spring the heath is alive with the song of Skylarks, Meadow Pipits and Linnets. Large numbers of Bumble Bees thrive on the colourful succession of bloom, beginning with the delicate red-green bells of Bilberry, followed by the purple haze of Ling and Bell Heather and the brilliant yellow of Western Gorse. Many rare invertebrates have been found on the mountain including a range of specialist heathland moths, two of which are native to North Wales.
The mountain wall demonstrates local dry stone construction dating back to the heyday of the nearby Penrhyn Quarry. Over time this wall has weathered and formed a rich growth of lichens thriving in the clean air and fresh westerly winds. A rabble of butterflies also inhabit the mountain wall, including Wall Brown butterflies patrolling their territories, migrants such as Red Admiral and Painted Lady congregate, and the Peacock butterfly is observed on the wing as early as mid-February.
A walk along the mountain reveals the subtle habitat variations caused by weather, geology and past management. The Moelyci site encompasses a fascinatingly varied geological section in a relatively small area. Recent Ice Age geology is wonderfully represented within the landscape, with moraine and esker gravel banks and "pingo" depressions formed by the melting of buried ice.
Car park, with disabled access, is available.
