Description

GLEN TARFF Glen Tarff SSSI is situated just south of Fort Augustus, on the southern tip of Loch Ness. It is the largest in a series of gorge woodlands in the Inverness District and runs for approximately 7.5 km from Corrieyairack Hill north to Loch Ness, into which the River Tarff flows. It is notified for its variety of woodland types and a rare beetle. The variable conditions of soil, slope and aspect has led to the development of different types of woodland, with sessile oak and birch on the sides of the gorge and ash, wych elm and alder lower down. The wood is notable for a well-developed under-storey of hazel, bird cherry, holly and goat willow. The site shows both oceanic and continental climatic influences and the woodland habitats reflect this. They are particularly rich in mosses and ferns, including the mountain fern Oreopteris limbosperma, and scaly male-fern Dryopteris affinis. There are also locally important plants such as wood crane’s-bill Geranium sylvaticum and the grasses mountain melick Melica nutans and wood fescue Festuca altissima. The site is also important for the rare beetle, Bolitophagus reticulatus, which in the UK is found only in the Highlands of Scotland. The beetle larvae feed on bracket fungus in old birchwoods.
