Coed Trellyniau once formed part of a larger woodland, known in medieval times as Coed y Gelli.
Situated within an agricultural landscape, it is linked to other woods by a network of ancient hedgerows, which offer a vital lifeline for a great number of birds and animals.
Swathes of wildflowers carpet the woodland floor in spring, including wood anemones, wild garlic, and bluebells.
HOW THE SITE IS MANAGED
The ancient woodland of Coed Trellyniau was cleared in the 1950s and replanted with pine and beech trees, which were grown as commercial crops. To restore the woodland to its natural state, the Wildlife Trust is encouraging native trees to regenerate by gradually thinning out the remaining beech trees.
