About the reserve


  • Spring is an exciting time with courting eider ducks and terns starting to arrive back on the reserve.  Thrift and sea campion are in flower.
  • In summer the three species of tern are busy feeding chicks.  You can see lots of ringed plover chicks as well.
  • In autumn there are large numbers of oyster catcher and curlew. The sea aster is in flower.
  • Winter is a great time to spot birds such as  brent geese, wigeon, knot and dunlin. You might also see long-tailed duck, Slovenian grebe or the occasional diver on the sea amongst thousands of eider.

At any time of year you might see seals. 

Island of pebbles

Foulney Island is formed entirely of pebbles that were brought from the Lake District to the coast by glaciers during the last ice age. Once a true island, Foulney Island is connected to the mainland by a man-made causeway built in the 19th century to prevent the Walney Channel from silting up. The saltmarsh to the east of the causeway has developed as a direct result.

Specialist plants

This is a great place to find specialist plants of shingle and saltmarsh. The vegetated shingle of the island itself is nationally important with species such as sea kale, sea campion and yellow horned poppy. On the saltmarsh you can find sea purslane, sea lavender and glasswort.

Breeding, migrating and wintering birds

Foulney Island is perhaps best known for its breeding terns which travel vast distances to nest on the island's shingle banks. Artic, common and little tern all breed here. Other breeding birds include ringed plover, oystercatcher, eider, skylark and meadow pipit. The island has a resident warden during the breeding season to monitor and protect the birds. In autumn and winter, curlew, dunlin, knot and oystercatcher may be seen in thousands and great-crested grebe, red-breasted merganser, cormorant and common scoter are frequently present offshore.

Keeping it special

Foulney Island has been leased and managed by Cumbria Wildlife Trust since 1974.
