3.3 Cuckmere Haven west, around saline lagoon TV 5154 9774 Date of visit: 16 September 2003. Surveyors: TY. Site Description: Area 0.45ha, 15% bare shingle. The site surveyed comprised the low lying are of shingle around a saline lagoon, backed by concrete tank traps from World War II, and part of the shingle slope. Management history: Cuckmere Haven has been extensively managed since medieval times. Shingle extraction from the beach occurred until around the 1950s and the area was used as a decoy using World War II. Hard defences at the base of the cliffs below the Coastguard Cottages and a lack of new material being added because of impeded longshore movement have resulted into a heavily eroded beach. The mouth of the river has been fixed in place since the early 1900s and wooden groynes were also put in place at around this time. Shingle is dredged out of the river mouth, recycled to the west beach then reprofiled at least twice a year. The site lies within the Seaford Head Local Nature Reserve and the Seaford to Beachy Head SSSI, designated in 1953. Damage/disturbance: Relatively little disturbance due to lagoon. Some evidence of rabbit grazing around the edges of the site. Habitat description: Saltmarsh community on shingle with a high diversity of species (53 recorded) Notable species: A. portulacoides, S. ramosissima, S. maritima, A. tripolium, B. vulgaris ssp. maritima, Salicornia sp., Cakile maritima. Also L. purpurea as it is a known larval food plant of the BAP and RDB3 species C. lunula (UK Biodiversity Group, 1999b; Clancy, 2001). Shingle habitat score: 0.3 Community type: a) Shingle community: No fit to any shingle communities. b) Broad shingle community: No fit c) NVC: Atriplex portulacoides dominated habitat similar to SM22 Halimione [Atriplex] portulacoides – Frankenia leavis saltmarsh or SM14 Halimione portulacoides saltmarsh community. d) Habitats Directive Annex I: No fit Table 14.
