Raasay SSSI Part 3

I returned to one of the two known Arabidopsis petraea (Northern Rock-cress) sites on Raasay where I had failed to find any plants last week. This time, armed with images from earlier years I succeeded, though the natural cycle of erosion and colonisation is putting this colony in danger. There again, another erosion event might provide bare rock with crevices that would be very suitable for Arabidopsis.

I returned to the proliferative deergrass and found much more. A specimen sent to Jeremy Roberts confirmed it as the hybrid Trichophorum x foersteri.

I also checked up on some Orthilia secunda (Serrated Wintergreen) in a site I hadn’t visited for over twenty years and nearby found a new site for Gymnocarpium dryopteris (Oak Fern).

There were several very fine specimens of Northern Eggar larvae around:

On Wednesday, members of the Skye Botany Group joined me to complete the southern part of the Raasay SSSI Site Condition Monitoring. We looked at two sites, one for Epipactis atrorubens (Dark-red Helleborine) and one for Dryas octopetala (Mountain Avens).
