The area drained by these rivers is of exceptional conservation value, particularly around the internationally important estuary, which has a Site of Special Scientific Interest designated as one of only three Biosphere Reserves in the UK.

THE BUILDINGS OF MORFA BORTH - the Marsh Harbour Ceredigion That part of Borth Village on a pebble bank with the sea on one side and the Cors Fochno marsh some reclaimed and the railway on the other. In the distance is the River Dyfi. Photograph Michael Lewis Photographs and History by BERYL LEWIS This work is for research and educational purposes only. AWELON Morfa Borth The first house in the old Township of Cyfoeth-y-brenin and at the north end of the village with the beach over the road. Formerly called Moreland (Moorland) House. The name Awelon in Welsh means ‘cheerful air’. Home of Theophilus and Frances Rees who took in holiday visitors and lodgers, as did carpenter and builder William Williams and his family. Built after 1859 but by 1871. Awelon in 2015. Awelon is an end of terrace house and two storeys high under a gable roof at right angles to the road and within the roof is an attic. The house is double fronted, and its walls are stone, probably rubble stone, and are rendered. The chimneys are narrow and of a dark brick. The four windows and front door seem to be symmetrical which is unusual for Borth. The windows are modern. There is a porch on the front with a sloping lean to roof with a door at the side, and a window with one large light facing the road. This has a quarry tiled floor. The front garden is enclosed by a low wall, and part is planted. Part of the north wall butts against Morlan Bwthyn but is not joined to it.
