Trodday and Eilean Flodigarry

Yesterday saw a group of seven of us hire a RIB (thanks, Andi) and head out to Trodday and Eilean Flodigarry from Staffin. Thanks are due to the Wild Flower Society for a grant towards this expedition as part of their contribution to Atlas 2020.

Trodday was last surveyed botanically in 1987 but the records were not split between the two tetrads and so none of them appear on tetrad distribution maps. Interestingly, 120 taxa were recorded then and 124 yesterday. Most, but not all, were common to both lists. The best finds yesterday were Dactylorhiza x formosa (D. maculata x purpurella), new to the 10 km square NG47 and Anagallis tenella (Bog Pimpernel) with only an unlocalised, undated but old record in NG47.

Flodigarry Island was also surveyed in 1987 when 108 taxa were found. This time we found 137 despite the evidence of considerable burning perhaps two or three years ago. New 10 km square records here were less significant: Dryopteris borreri (a Scaly Male-fern) which would have been recorded as the common aggregate if we had not had James with us as a fern expert, Elytrigia repens (Common Couch) (!) and and a variety of Salix repens (Creeping Willow): var. argentea with silvery foliage.

This effect on Eleocharis palustris (Common Spike-rush) is curious, though I feel as though I have seen it before locally:

and James spotted this on a grass – a white patch at the same point on each stalk, which I now (LATER) think is the choke fungus Epichloë festucae:

Nick did well for bryophytes including the liverwort Geocalyx graveolens on Flodigarry Island which is listed as Vulnerable in the British Red List. Bob and Martin had good bird lists and we also recorded a few other things especially butterflies and moths.

The scenery was special too:
