| A Review of the scarce and threatened spiders (Araneae) of Great Britain: Species Status No. 22 (Sep 2017) | Red listing based on 2001 IUCN guidelines | Critically Endangered (possibly extinct) | 42979 | The only British records of this species are two males and six females found at two sites in the Cairngorms in 1979 and 1980, at an altitude of 900-980m. Despite some targeted searches, it has not subsequently been re-discovered. It is unlikely that recreational pressures are important for this species, given the area of similar Empetrum/Vaccinium habitat available. The key threats are likely to be climate change, affecting the vertical zone it can occupy, with little scope for adaptation or migration, and nitrogen deposition affecting vegetation composition and structure. Threats: There have been proposals for skiing developments close to the sites where this species was found. Lurcher's Gully was the subject of a public inquiry in 1981 and the proposals were rejected at that time. In the late 1980s there were further proposals for another ski-tow, a café and other means of access, but these may not be permitted now that the structure plan for the area shows a presumption in favour of conservation. The compaction of snow caused by heavy skiing can have severely damaging effects on upland vegetation, which, owing to its slow growth, is unable to recover during the summer months. Snow-fences increase the duration of the snow cover, which causes the vegetation to change from dwarf heath to a Nardus stricta sward. Such a change in the vegetation structure is not likely to be within the tolerance limits of this spider. |
