Sandscale Haws is one of the few remaining breeding sites for the endangered natterjack toad in Britain.
The reserve contains nearly 600 species of flowering plants, representing about 20% of the UK's total flora.
It is home to the rare petalwort, a tiny liverwort that grows in the damp dune slacks.
The dunes are subject to natural 'blowouts,' where wind removes sand to create new, bare areas essential for pioneer plant species.
The site hosts a unique subspecies of the northern dune tiger beetle, which is only found in this part of Northwest England.
The area was historically used for military training during World War II, and unexploded ordnance occasionally surfaced due to coastal shifts.
The dune slacks act as seasonal wetlands, filling with rainwater during winter and spring.
Sandscale Haws is a dynamic dune system located on the Duddon Estuary in Cumbria, managed by the National Trust. It supports a unique ecosystem comprising shifting dunes, sandy beaches, and salt marshes. The site is a designated Site of Special Scientific Interest (SSSI) due to its rare flora and fauna. It hosts a significant proportion of the UK's population of natterjack toads during their spring breeding season. The landscape is characterized by a high diversity of orchid species, including the rare dune helleborine. Visitors walk through a mosaic of habitats ranging from damp hollows called slacks to dry, sandy ridges. The estuary location provides expansive views of the Lake District fells across the water. Coastal erosion and sand deposition constantly reshape the dune topography.
The high dune ridges looking north toward the Black Combe fell during golden hour.
Wear waterproof footwear as the dune slacks can remain boggy or flooded even in dry weather.
Stay on marked paths to protect the fragile marram grass and rare dune vegetation.
Keep dogs on a short lead, especially near water, to avoid disturbing the natterjack toad population.
Walking across the mudflats of the Duddon Estuary, which are treacherous due to shifting sands and rapidly rising tides.
Do not disturb wildlife, avoid trampling on fragile dune vegetation, and remove all waste to protect the sensitive ecosystem.
