December 21, 2024, Taf Fechan Local Nature Reserve

Ancient broadleaved woodlands, calcareous grasslands, river, and cliffs. Part of the Cwm Taff Fechan Woodlands SSSI, and a Local Nature Reserve. Taf Fechan LNR comprises about 2.5 km of river with steep valley sides of Carboniferous limestone. The river has eroded the limestone into a narrow gorge in the centre of the site. A mosaic of deciduous woodland on the slopes with a canopy of Beech, Birch and Ash, gives way to Alder and Grey Willow closer to the river, together with Hawthorn scrub, calcareous grassland, heathland, wet flushes, and tufa formations. The valley is one of the best recorded sites for bryophytes in Glamorgan. Please note that the river next to the Gurnos quarry may contain unseen hazards and as a result the Trust does not consider the site suitable for wild swimming or play.

High above the A470 to the north of Quaker’s Yard, the Giant’s Bite is a dramatic gap in the skyline quarried from the ridge top at the former Cefn Glas mine and quarry. ❤️👌 The site was intensively grazed up to the mid-1990s when a large belt of native trees were planted on the lower slopes. These trees are now maturing and have helped to heal the visible mining scares. The shales forming the upper soil horizons support a wide variety of native flowering grassland species including wild strawberry, cowslip, foxglove and wild thyme, and the site is increasingly becoming re-vegetated by scrub species. Incredibly Fine views of the Taff and Cynon valleys are afforded from the summit ridge, while the line of the former Glamorganshire Canal is also discernible.
