The Arish Burn

Nick came to do the bryophyte survey in connection with the proposed hydroelectric scheme on Tuesday and I went along for the ride. It was the best day this week weather-wise and I was able to do some preliminary  vascular plant recording as well as being the official photographer.   However, several things really will have to wait until later in the season – some grasses and sedges plus orchids, if any.

We spotted some tufa forming on what Nick identified as Palustriella commutata

Nick found one Nationally Scarce moss, Gymnostomum calcareum, but there are several sites for it on Raasay.

One section of the burn was unfamiliar to me and it may be that I have never got there before. Until a few years ago it would have been hidden in the middle of a conifer plantation and it may have been missed. Anyway, like other parts of the burn it shows some influence of basic rocks and had Galium odoratum (Woodruff). Plants fully in flower included Chrysosplenium oppositifolium (Opposite-leaved Golden-saxifrage), Luzula sylvatica (Great Wood-rush), Primula vulgaris (Primrose)and Viola riviniana (Common Dog-violet).
