Coal spoil at Penygroes

A total of 60 bryos were recorded growing directly on coal spoil at this development site in Penygroes, vc44. Most interest was focused on the mildly basic 'Cratoneuron filicinum-Bryum pseudotriquetrum' seepages found around the margins of the site, with noteworthy species including Bryoerythrophyllum ferruginascens and Palustriella falcata. Both were rare on site and it's the first time that I have encountered the latter on spoil, the location of the only patch I saw shown below. 

The central plateau was much less interesting, being dominated by Campylopus introflexus and Lotus corniculatus, which together with locally frequent Cladonia spp. formed a distinctive coal spoil community.
