SoDdGA Gweunydd Nant y Twyn - Arolwg Dosbarthiad Llystyfiant Cenedlaethol (2024)
A standard Phase 2 NVC survey was undertaken at Gweunydd Nant y Twyn as part of the Site of Special Scientific Interest (SSSI) designation process.
Gweunydd Nant y Twyn consists of a cluster of small fields, with tall, wooded hedgerows. The site is of particular importance for bryophytes.
The site comprises the original Phase 2 site survey site of Mockridge et al. 1998, which has now been resurveyed (2024) and extended to include several contiguous small fields, and a further extension centred on 5 small nearby fields, approximately 1/3rd of a km to the north, linked by a block of woodland and pasture. The total area of the Phase 2 survey site is now 39.9ha.

Standard National Vegetation Classification (NVC) survey techniques were used. The survey was carried out in-house by Natural Resources Wales (NRW) staff.
Note, the Phase 2 survey site boundary does not coincide with the Gweunydd Nant y Twyn SSSI boundary, which excludes certain fields of more modified grassland.
Currently we are unable release this data, as the SSSI is undesignated. In addition, one of the files contains sensitive species.
