Distribution
E. oelandica has been recorded from a few localities in the mid-south and south-east of England, with the most recent record from Juniper Hall, Surrey. The Norfolk record mapped for Norfolk in Harvey et al. (2002) is in fact E. mordax and other old coastal records may be misidentifications for this species. The species has been recorded from France, Belgium, Germany and Switzerland, and is on the Red List for Sweden (Gärdenfors 2000).Habitat and ecology
This species has been recorded from sand dunes, dry sandy heaths and grassland. It is found under stones or among vegetation. Adults have been recorded between May and August while females alone have been found in September.Status
Recorded from a single site since 1992, as against four recorded hectads with spider records before this date.Threats
Public pressure on coastal sites can degrade these habitats through trampling, while fragmentation and loss of heathland to agriculture and forestry is another threat. The remaining areas are at risk from fires and scrub encroachment.Management and conservation
Many of the sites are managed by conservation bodies. Scrub invasion should be controlled by grazing, mowing or controlled burning. Text based on Dawson, I.K., Harvey, P.R., Merrett, P. & Russell-Smith, A.R. (in prep.).Stats
