Description :
A vegetation survey in the vicinity of Kinnvika in Murchisonfjord, Nordaustlandet, was carried out at 23 sites ranging from sparsely vegetated to almost complete cover on the slopes under a birdcliff. In total, 36 vascular plant species were recorded in the area, 28 species under a birdcliff and 21 species at the other sites. At moisture limited sites, recruiting plant density significantly correlated to cyanobacterial crust cover. This crust ameliorates the substrate surface providing moisture, warmth, nutrients and a more stable environment for establishing plants, and is thus of major importance for plant community development in High Arctic polar deserts.
