Nordvesthjørnet's vegetationBy Øystein Overrein (ed.), Jørn Henriksen, Bjørn Fossli Johansen, Kristin PrestvoldThe vegetation in the area is mostly influenced by soil and climate. The soil follows the bedrock in the area, while the climate changes slightly from the outer coastline in the west, to Raudfjorden in the east. The basement rocks in the far north-west (Smeerenburgfjorden and the larger islands) consist of silica-rich gneisses and granites, which results in rather poor vegetation (except underneath the bird cliffs). The Devonian sandstones along Raudfjorden are rich in carbonate and form fine-grained, Ca-rich reddish soil. For vegetation that thrives on calcium, this provides fertile conditions.* Updated June 2015 |
