Essex Red Data List comment
Tidal habitat.

Species text
The species was found in tidal litter on the shell shingle bank to the south of Piers Marsh. It probably occurs in similar habitat at other points around the reserve. In Britain the spider is confined to strand-line litter and under stones on the banks of tidal rivers or on estuaries and saltmarshes, but most records are from the east coast between Lincolnshire and Kent. Pollution on some rivers and loss of saltmarsh to land reclamation may threaten the species at some sites. Sea level rise and saltmarsh erosion are more likely to threaten the species on the Essex coast. Retention of strand-line litter is important (Harvey et al. 2002). References
