Mosses over the sea

There is very little land in ST1971 but this monad does include the outer portion of Penarth Pier. A trip with the family last weekend revealed six species growing on the wooden deck of the pier, directly above the sea at high tide but presumably elevated enough to limit the influence of salt. The species were Bryum capillare, B. argentuem, B. dichotomum, Ceratodon purpureus, Hypnum cupressiforme and Dicranoweissia cirrata.
