About the reserve

Whilst protected specifically for rare plant species such as variegated horsetail and sharp rush, the reserve is also home to dune specialist invertebrates, amphibians, and reptiles. Scrub and willow provide nesting opportunities for spring migrant birds such as chiffchaff, willow warbler, and whitethroat, while ground-nesting species such as oystercatcher and reed bunting find cover in the long grass.
