Tarnbrook Moss Tarnbrook Moss is a raised peat bog and wetland complex in Cumbria within the Lake District National Park. The site is notable for intact peat layers, diverse mire vegetation, and as habitat for specialist invertebrates, birds, and bryophytes. Tarnbrook Moss has been the focus of conservation designations and long-term hydrological research involving national and international bodies.
Tarnbrook Moss lies on the western fringe of the Pennines near the valley of the River Duddon and the settlement of Coniston. The mire occupies a plateau between the Duddon Valley and the headwaters of the River Leven, rising to approximately 240 metres above sea level. Surrounding features include the fells of The Old Man of Coniston, Wrynose Pass, and the upland commons of Seathwaite Fell. Access routes link to the A593 and the minor roads toward Torver and Hawkshead.
Tarnbrook Moss sits on late Carboniferous and Permian sedimentary bedrock overlain by glacial till and windblown peat deposits. The bog is a classic raised mire with a domed peat profile reaching depths over three metres in places, formed since the beginning of the Holocene epoch. Groundwater flow is influenced by permeable gravel outwash from Pleistocene glaciation and impermeable clay units; local springs feed headwaters of the River Duddon and tributaries to the Leven. Hydrological studies by the United Kingdom Centre for Ecology & Hydrology and Natural England have documented water table dynamics, surface runoff, and peat carbon accumulation. Historical peat extraction and drainage for agriculture and grouse moor management altered hydrology until restoration schemes reinstated raised water tables using ditch-blocking and revegetation.
Tarnbrook Moss supports a mosaic of ombrotrophic bog, fen, wet heath, wet flushes, and acid grassland. Typical species assemblages include blanket bog specialists such as Sphagnum magellanicum, Sphagnum capillifolium, and Erica tetralix, alongside carr dominated by Betula pubescens and Salix spp.. The site hosts breeding populations of curlew, lapwing, snipe, and overwintering whooper swan in adjacent tarns. Notable invertebrates include the Coenonympha tullia, peatland craneflies, and ground beetles studied by the Natural History Museum, London. Bryophyte and lichen communities have affinities with western oceanic mires and show links to sites in Snowdonia, Dartmoor, and western Scotland.
Human interaction with the Tarnbrook Moss landscape dates to prehistoric peat cutting and turf use recorded in nearby archaeological surveys alongside Bronze Age cairns on adjacent fells. Medieval and post-medieval transhumance by upland shepherds from Lancashire and Cumberland shaped commons management; records in the National Archives (UK) reference grazing rights and enclosure disputes. In the 19th century industrial peat extraction and drainage occurred to fuel local ironworks in Barrow-in-Furness and to improve pasture for sheep farming. 20th-century scientific interest brought peat science expeditions from the University of Oxford, University of Manchester, and the University of Glasgow, resulting in published surveys in journals associated with the British Ecological Society. Post-war conservation impetus led to statutory designations and restoration projects led by Natural England and regional wildlife trusts.
Tarnbrook Moss is designated as a Site of Special Scientific Interest and forms part of a designated Ramsar site for lowland peatland. Management objectives are coordinated by Natural England in partnership with the Cumbria Wildlife Trust, local landowners, and the Environment Agency. Active restoration includes blocking drainage ditches, re-establishing Sphagnum populations, controlling invasive Rhynchospora alba in certain compartments, and rewetting to enhance carbon sequestration and biodiversity. Long-term monitoring programs on peat depth, greenhouse gas fluxes, and bird populations involve collaborations with the UK Centre for Ecology & Hydrology, University of Lancaster, and international peatland networks such as the International Mire Conservation Group. Agri-environment schemes under the Common Agricultural Policy and successor rural development programs provide incentives for low-intensity grazing and restoration-compatible practices.
Public access is available via footpaths connecting to trails around Coniston Water and the western Lake District fells, with nearest parking at Torver and public transport links from Ulverston and Coniston. The site is used for low-impact recreation: birdwatching, bryology fieldwork, and guided nature walks by the Cumbria Wildlife Trust and local volunteer groups. To protect sensitive habitat, access to some compartments is seasonally restricted, enforced under SSSI regulations administered by Natural England. Visitors are encouraged to follow promoted access routes linking to rights of way network maintained by Cumbria County Council and to consult information provided by the Lake District National Park Authority.
