Description

Strathfleet Strathfleet Site of Special Scientific Interest (SSSI) is located on steep slopes between the Mound causeway and Rogart in east Sutherland. The site has been designated for its nationally important rock outcrops, oak woodland and range of rare plant species. Moine (Geology) The rocks of Strathfleet SSSI are around 1000 million years old and form part of the ‘Moine Supergroup’ rocks. Around 425 million years ago, these rocks were partially melted by extreme heat to a molten ‘tonalite’ rock which now forms part of the ‘Rogart pluton’. A pluton is a mass of rock that was originally magma which solidified as it moved towards the Earth’s surface. The Moine rocks formed through the metamorphism of sedimentary rocks, such as sandstones and mudstones. These rocks were first metamorphosed at high pressure during a large-scale mountain building event, and then subjected to the high temperatures which partially melted them and changed them into a rock type known as ‘migmatite’. The migmatite zone around the Rogart pluton varies in width. Strathfleet SSSI exhibits an excellent section through the thickest part of the migmatite zone. It is one of the most readily accessible and detailed sections through a migmatite zone to be found in great Britain. Upland oak woodland The semi-natural upland oak woodland at Morvich is the most northerly oak wood of significance in eastern Scotland. Although this oak wood is relatively small, compared to other southern oak woodlands, it supports some impressive veteran oaks and a good range of typical woodland species for this habitat type. Site code: 1491 In addition to oak Quercus petraea/ robur, commonly occurring tree species are birch , hazel Corylus avellana, rowan Sorbus aucuparia and alder Alnus . The understorey is open with woody shrubs being uncommon, although gorse (whin) Ulex europaeus is locally common. The ground flora is largely dominated by grasses; wavy-hair grass Deschampsia cespitosa and sweet-vernal grass Anthoxanthum odoratum, and woodland herbs, such as; common cow-wheat Melampyrum pratense, wood sorrel Oxalis acetosella and wood sage Teucrium scorodonia. The oak woodland also supports a good range of lichens growing on tree branches and high stems. Vascular plant assemblage Due to the varied underlying rock types and associated soils, the site supports a nationally important assemblage of plant species. Of particular note is a population of the nationally rare rock cinquefoil Potentilla rupestris, known to exist at only two sites in Scotland. Other scarce plant species that also contribute to this assemblage include rock whitebeam Sorbus rupicola and pyramidal bugle Ajuga pyramidalis.
