Description

Loch Beannach Islands Loch Beannach Islands Site of Special Scientific Interest (SSSI) comprises the eastern half of Loch Beannach, approximately 6km northeast of Lochinver, Sutherland. This site is nationally important for the birch woodland on eight islands within Loch Beannach. The islands of Loch Beannach support birch-rowan woodland with an unusually diverse ground flora. The woodland canopy is dominated by birch Betula pubescens and rowan Sorbus aucuparia with aspen, holly and a shoreline fringe of alder Alnus glutinosa. Juniper Juniperus communis occurs on some of the islands and the brown earth soils support a comparatively rich flora including bluebell Hyacinthoides non-scripta, red campion Silene dioica, climbing corydalis Ceratocapnos claviculata, herb robert Geranium robertianum, wild angelica Angelica sylvestris and hay-scented buckler-fern Dryopteris aemula.

Insects to look out for

These moths, butterflies and beetles are known to feed on plants recorded at this site, and carry a notable UK conservation status — but a host-plant being present doesn't mean the insect has actually been recorded here. Treat this as "worth watching for," not a confirmed sighting.
