ARCTIC FOX (ALOPEX-LAGOPUS) DENS IN THE DISKO BAY AREA, WEST GREENLAND

Seventeen arctic fox (Alopexlagopus) dens in the Disko Bay area, West Greenland are described regarding location, type, size and vegetation cover. The dens were found in ridges, screes and level ground, mainly in areas of dwarf-scrub heath. The mean number of entrances was 17.8 /- 18.4 SD (range 1-63), with more than half of the dens having fewer than 10 entrances. For dens in slopes, there was a prevalence for sout h-facing slopes, but for dens with an open exposure, entrances were mo st frequently oriented towards the north and east. The dens were not f ound to be lush green, as reported from several other areas. A visual difference between the den vegetation and the surrounding vegetation c ould only be recognized at a few den sites. A vegetation analysis reve aled a significant difference between the den and the surrounding area in the occurrence of eight plant species. Among the species occurring more frequently on the den than in the adjacent area, Stellaria longi pes was the most conspicuous because of its white flowers. This specie s is therefore suggested as a guide species in the search for new dens in the Disko Bay area. Dens with recent fox activity were larger and more conspicuous than dens without sign of recent activity.
