Bosherston Lakes is a series of shallow interconnected ornamental lakes and ponds within the Stackpole Estate in Pembrokeshire Coast National Park, Wales, in the United Kingdom. Created in the late 18th century as part of landscape works associated with Stackpole Court and the Bosherton demesne, the lakes form a notable wetland complex adjacent to Llanstadwell, Castlemartin Range, and the Pembrokeshire Coast Path. The site is managed for its heritage, biodiversity and public access by organisations including the National Trust (United Kingdom) and is designated within multiple statutory and non-statutory conservation frameworks such as Site of Special Scientific Interest and Ramsar Convention-related registers.
The landscape unit comprises a chain of ponds and broad shallow lakes fed by local tributaries associated with the River Cleddau catchment and set against the backdrop of the Stackpole Estate designed landscape, near coastal features such as Barafundle Bay and Broad Haven. Its geomorphology and designed features reflect influences from 18th-century landscape architects working for families like the Cawdor family and the Duty family who held the Stackpole demesne; the area has been the subject of studies by scholars from institutions such as University of Wales Trinity Saint David, Cardiff University, and the Royal Commission on the Ancient and Historical Monuments of Wales.
Hydrologically the lake system occupies low-lying fen and valley bottom in the eastern sector of the Pembrokeshire Coast National Park adjacent to the coastal promontory of Stackpole Head and drains toward Broad Haven and St Bride's Bay. Surface water inputs include small streams originating near Cresswell Quay and drainage channels cut during the creation of the ornamental lakes in the 18th century, with subsurface flows interacting with the local aquifer systems mapped by British Geological Survey. The morphology shows artificial embankments, sluice arrangements historically linked to the estate's water management practices and links with engineered water bodies at St Govan's Chapel environs; modern management interfaces with statutory flood risk regimes administered by Pembrokeshire County Council and environmental regulation from Natural Resources Wales.
The lake chain supports assemblages of wetland flora and fauna, with emergent and submerged communities including beds of Najas marina-type submerged aquatic vegetation historically recorded alongside reedbeds dominated by species common to Severn Estuary-influenced wetlands; surveys by Natural England-equivalent bodies have recorded rich macroinvertebrate and aquatic plant diversity. Avifauna includes regular records of species monitored under schemes run by Royal Society for the Protection of Birds and the British Trust for Ornithology such as mute swan-linked populations, passage waders, and wintering waterfowl noted in systematic counts akin to the Wetland Bird Survey. The site supports amphibians and fish communities influenced by stocking and connectivity to wider river systems; conservationists from groups like Wildfowl & Wetlands Trust and researchers at Bangor University have undertaken fieldwork assessing invasive species management and habitat restoration techniques.
The lakes were formed as part of the designed landscape of the Stackpole Estate in the 18th century during ownership transitions involving families connected to wider aristocratic networks in Wales and England. Estate works were contemporaneous with landscape movements linked to figures associated with the Picturesque movement and echo broader patterns seen at country houses such as Powis Castle and Stourhead. The lakes and their associated structures—bridges, boathouses and gate features—feature in archival holdings of the National Library of Wales and photographs in collections curated by the Royal Commission on the Ancient and Historical Monuments of Wales. Archaeological and documentary records indicate interactions with regional historical events, local parish narratives from Stackpole and Castlemartin communities, and land-use changes recorded in Tithe maps and Victorian-era cartography by the Ordnance Survey.
As part of the Pembrokeshire Coast National Park and near long-distance routes such as the Pembrokeshire Coast Path, the lake complex is a destination for walkers, birdwatchers, photographers and educational groups from organisations like the Ramblers Association and British Association for Shooting and Conservation members. The National Trust (United Kingdom) provides visitor information, waymarked trails, and interpretation linking to nearby attractions including Stackpole Quay, Barafundle Bay, and historic properties such as Stackpole Court ruins; visitor management interfaces with transport links to Milford Haven and accommodation networks in Pembroke and Tenby. Events and guided walks organised by local societies and voluntary groups often coordinate with county-level tourism initiatives led by Visit Wales.
Current management balances heritage conservation, biodiversity objectives and public access under frameworks administered by National Trust (United Kingdom), Natural Resources Wales, and statutory designations such as Site of Special Scientific Interest. Conservation measures address water quality, invasive non-native species, reedbed management, and fen restoration drawing on best-practice guidance from bodies including the Environment Agency (England and Wales) predecessors, Centre for Ecology & Hydrology, and academic research from Swansea University. Collaborative projects have engaged NGOs, local communities, and research councils to monitor ecological change, align with UK Biodiversity Action Plan targets and report under international commitments such as conventions to which the United Kingdom is a signatory.
