The Allt Daraich runs from Coire na Sgairde into the River Sligachan just before the latter reaches the sea. There is a long gorge where Hymenophyllum wilsonii (Wilson’s Filmy-fern) was recorded in 1968 and 1976. I had a quick look today but failed to find any. However, there was a fair bit of water in the burn, limiting access, and an awful lot of gorge to search.
The burn has some very attractive stretches:
Botanically, the most noticeable feature was the alien shrubs along the gorge. There were huge numbers (many hundreds, perhaps thousands) of Berberis darwinii (Darwin’s Barberry) and Gaultheria mucronata (Prickly Heath), a lot of Rhododendron ponticum (Rhododendron) and quite a few plants of Rubus laciniatus (Cut-leaved Bramble).
