7 Overview

The site is comprised of 2 sectors, an intertidal sector comprising of rocky shore, sandy bays and shingle shore. A second, inland sector consists of machair plain, marsh, and wet moorland with several small lochs and numerous pools, and also one large freshwater loch. The inland areas provide roost sites for internationally important numbers of wintering geese from Greenland and breeding sites for a variety of wader species, while the intertidal sectors support internationally important numbers of wintering wader populations. Several of the lochs are of international importance for their rich aquatic plant communities which include a range of nationally scarce and nationally rare species, while the site provides excellent representation of dune and machair habitats, also of international importance.

12 Justification of criteria

Criterion 1. The site supports substantial areas of freshwater loch, freshwater marsh, wet machair and maritime grassland all of which are in near-natural condition. One of the lochs is of international importance as an example of a eutrophic machair loch; this and several other lochs are of international importance for their rich aquatic plant communities which include the nationally rare Shetland pondweed Potamogeton rutilis and a range of nationally scarce aquatic vascular plants and charaphytes. The site provides one of the best examples in Britain of machair habitat (including the associated machair loch) which has a very restricted world distribution.

Ramsar criterion 6 During the Breeding Season the site regularly supports internationally important populations of: Dunlin Calidris alpina schinzii. Over winter the site regularly supports internationally important populations of: Barnacle Goose Branta leucopsis, Ringed Plover Charadrius hiaticula, Turnstone Arenaria interpres, White-fronted Goose Anser albifrons

16 Ecological features

The intertidal sector comprises of rocky shore, shingle shore and sandy shore. The inland sector is largely moorland with frequent pools and lochans. The predominant vegetation is wet heathland with abundant Calluna vulgaris, Erica tetralix and Scirpus caespitosus; there are also areas of marsh and fen. The substrate is generally wet and locally boggy. There is also an area of machair plain grading from low dune into wet machair. There is one large eutrophic freshwater loch (Loch a’Phuill) with high pH levels, and several smaller lochs. Several of the lochs support diverse communities of aquatic plants including a variety of Potamogeton species.

Site vulnerability and management statement. Sheep and/or cattle grazing is the main land use over most of the site; the continuation of low-intensity grazing regimes will help to maintain the special interest of the site. Crofters undertake occasional ditch creation or clearance on the wet moorland areas, and in some cases this is likely to affect the qualifying interests. However this will continue to be addressed through management agreements or agri-environment schemes as necessary. Groundwater extraction for public use takes place from Loch a’Phuill and its vicinity and could have a localised impact on the qualifying interests, this issue is addressed through discussion with the local water authority. Small-scale sand and gravel extraction takes place from intertidal and machair areas, and is locally impacting on the qualifying interest. However, this issue is being addressed through the development of an aggregates strategy by a partnership between SNH, the local authority and islanders. Much of the site is entered into an agri-environment scheme which promotes overall conservation management.

25 Current scientific research/survey/monitoring and facilities

- Monitoring of bird populations at the Reef sector of the site is undertaken by RSPB.
- Monitoring of qualifying features will be undertaken by SNH as part of its Site Condition Monitoring programme.

26 Current conservation education

27 Current recreation and tourism

Parts of the site used for informal recreation (walking, wildlife watching, etc) by locals and visitors, particularly in summer. Wind-surfing takes place on several of the beaches, mainly in autumn. There is occasional freshwater fishing on Loch a’Phuill. Wildfowling takes place in season.
