The Nature of Bannau Brycheiniog -Craig Cerrig Gleisiad

Join me at Craig Cerrig Gleisiad, one of the most remarkable landscapes in Bannau Brycheiniog National Park, where geology, glaciation and ecology come together in a spectacular natural setting. At the heart of the reserve lies a dramatic north-facing glacial cwm, carved by ice during the last Ice Age and framed by towering cliffs, moraine ridges and a vast natural amphitheatre. The landscape also bears the scars of a massive post-glacial landslide, while the exposed cliffs reveal 400-million-year-old Devonian Old Red Sandstone.

What makes this place special is the way its geology continues to shape the living world. The cool, sheltered cliffs and inaccessible ledges have provided refuge for rare Arctic-alpine plants that have survived here since the glaciers retreated. Species such as purple saxifrage, mossy saxifrage and roseroot persist on the crags, protected from grazing animals by the steep terrain. Across the reserve a rich mosaic of habitats, including rock faces, scree slopes, heather moorland, peat bogs, streams and woodland, supports a remarkable diversity of plants, birds, mosses and insects.

Through observation, discussion and exploration, this workshop will investigate how the landscapes we see today are shaped by ancient geological forces, and how the plants and wildlife of Craig Cerrig Gleisiad remain living legacies of the Ice Age.

We'll be out all day, whatever the weather some come dressed and prepared. Don't forget our lunch and drink

There’ll be a CPD point for MTA
