In 1916, this area was noted as 'bogs and woods' alongside Deer Dike Moss and three other sites. Although the mosses had already been cut over for peat, they were well-regarded for plants, birds and moths. Now the Roudsea Wood and Mosses Site of Special Scientific Interest (SSSI), the site consists of coastal saltmarsh, acid and limestone woodlands, and lowland raised bog. It supports all kinds of wildlife including over 280 species of fungi, and rare plants like Lancashire whitebeam and true fox sedge. Dormouse, red squirrel and otter frequent the site; while birds such as nightjar and skylark breed here. Now managed by Natural England.
