National Distribution

About this species

Recorded altitude range
0m to 5m

Species text

Distribution
British records are all from the east and south-east coasts of England from Norfolk to Kent. The species is mainly coastal in distribution, whereas C. similis, with which it was formerly confused, is a Central European and more upland species.

Habitat and ecology
Coastal sand dunes. The spider occurs in marram tussocks on sand dunes. Adults have been recorded in May and June and again in September and October.

Status
Recorded from only five hectads since 1992, with no evidence of decline but always at risk from leisure use of its dune habitat, the construction of coastal defences and other infrastructure development.

Threats
Public pressure can cause damage to the fragile dune vegetation, destroying it by too much trampling or by climbing in the steeper dunes. Possibly holiday development has destroyed some habitat, and this is always a threat to coastal dunes which lack statutory protection. Sand dunes are popular sites for golf courses (Sandwich Dunes now supports three) and the associated buildings, roads and re-profiling and reseeding of the dunes cause damage to the natural ecosystem. Several sites where it occurs, such as Minsmere, are nature reserves. Sea level rise is a potential future threat to existing sites.

Management and conservation
Ensure dune habitats are managed to reduce damage caused by recreational pressures and holiday development.
