Rhos pastures are a special habitat found in Wales. They consist of flower rich grasslands which contain a mixture of heathland and purple moor grass vegetation. The name, which has come to be used in other parts of the UK, derives from the Welsh word "rhos" meaning "heath".
These delightful flowery meadows delight the eye during the spring and summer months and are important habitats for many rare species of wildlife such as the Marsh Fritillary butterfly.
They are becoming increasingly rare due to agricultural threats and many important examples have been obliterated for ever due to Opencast Mining.
The Selar Farm SSSI was obliterated by one such mine dug by Celtic Energy in the mid 1990s and now they are proposing the Selar North extension.
