Bedrock dominated by a forest of L. hyperborea with a lower limit of 17 m, and a sparse undergrowth flora, the rock surface mainly dominated by Lithothamnion. Echinus common and a variety of other echinoderms especially Luidia, Marthasterias and Antedon. Caryophyllia abundant and Corynactis viridis common in patches on vertical surfaces. Many crevices providing shelter for species such as Munida and Cucumaria.

The kelp forest had a heavy growth of epiphytic algae but undergrown algae were poor, and animal species few. Antedon was the predomiant species on vertical surfaces. Foliaceous algae frequent on the sediment plain (about 30% cover), attached to debris.

The level of the water is only slightly affected by the tides due to the stone embankment (Nicol, 1936) but the loch is predominantly marine in character since there is little freshwater inflow. The margins of the loch are low and are edged with stones, boulders and bedrock with a good cover of lichens above the water line. The bottom of the loch is composed of small stones and boulders extending out for a varying distance and giving way to soft mud with distinct smell of hydrogen sulphide indicating deoxygenation. The high salinity allows the development of an extensive algal cover in the shallower parts, consisting mainly of species normally found intertidally. A total species list is given in Appendix V, and includes previous records from Nicol, 1936. At the Eastern end of the loch, there was a dense growth of algae with Ascophyllum nodosum, Fucus vesicolosus and Fucus serratus (very wide fronds) predominant around the edges and the 'cape' form of Laminaria saccharina further out. Beneath this was a dense growth of Furcellaria lumbricalis with Mesogloia as an epiphyte. These species were common around the whole loch. In the Western arm Codium fragile was also locally common as was Enteromorpha intestinalis wherever there was significant freshwater runoff. At the North-east end (Site 13) a small sandy bay supported a bed of Zostera marina and dense wiry mats of Vaucheria litorea. The fauna was fairly diverse although limited to somewhat euryhaline species. Undersides of stones supported large numbers of Dendrodoa grossularia and encrusting bryozoa. Large masses of Halichondrea panicea covered both rocks and algae. A dive in the Eastern end showed much of this to be green in colour and covered in gas bubbles suggesting the presence of symbiotic algae. Scyphistomae of Aurelia were also found on rock faces at this end. The soft mud beyond the stones supports little life but small soft specimens of Asterias rubens were common (c.f. Loch Obisary). The 'rapids' formed by the outflow of water on the ebb tide made this area the richest in terms of species, and this area also has the highest salinity. The L. saccharina and fucoids in this region bore epiphytic growths of hydroids and bryozoa and also of Spirorbis. Barnacle spat was common on the rocks. The largest growths of Halichondria were found here. Littorina saxatilis was locally extremely abundant along the Western arm and L. littorea and L. littoralis were also common. Sandy areas supported numbers of Cardium edule and Nicol also recorded Macoma balthica.

Disused wooden pier present. Rock dominated by L. saccharina with a sparse undergrowth of red algae. Caryophyllia smithii, Ascidiella aspersa and Clavelina common on rock. Heavy covering of silt on rock and Laminaria. Much debris on mud surface including stones, shells and artefacts providing a substratum for foliaceous algae, ascidians and occasional Laminaria. Mud well worked, characterised by Virgularia and Cerianthus and rich in infaunal annelids and bivalves.
