About this species

Recorded altitude range
6m to 400m

Species text

Distribution
The species has scattered and patchy records in England, Wales and Scotland and is apparently absent from some parts of the country which would appear to contain suitable habitat. For example, it has been fairly common in wet wooded areas on heathland in Surrey and the New Forest, but has never been recorded from the many similar areas in Dorset. It has also been recorded from Redgrave and Lopham Fens, but not from the better-known Wicken or Woodwalton Fens. The species is widespread in northern and central Europe.

Habitat and ecology
N. sarcinatus occurs among wet, usually tall, moss (Sphagnum, Polytrichum, etc.), often under pine or other trees in swampy places, often in heathland areas, or sometimes in fens. Both sexes are adult in autumn, winter and spring.

Status
UK Biodiversity Action Plan priority species. The spider has been common at some sites, but local. There appears to be a major decline in England and Wales, especially in the south and east.

Threats
The loss or drainage of heathland for agriculture, forestry or development. Although it is often found in wooded areas, it is less likely to be able to survive in the generally drier and more disturbed conditions under forestry plantations.

Management and conservation
Maintain swampy areas with trees on heathland.
