The spider is local and not common on high mountains. All recent records are from Scotland, where it is widespread, except one in N. Wales.Threats
At some sites, recreational development (including for skiing) could represent a threat. In the longer term, global warming as a result of climate change represents a threat to this and other montane species in Britain. The ecology of this species requires further research to determine what threats it faces at present.Management and conservation
Protect montane sites from excessive recreational development. Text based on Dawson, I.K., Harvey, P.R., Merrett, P. & Russell-Smith, A.R. (in prep.).Stats
