Gróðrarleivdir (sáð) av dvørgabjørk (Betula nana) í Føroyum: A pollendiagram from the Faroe Islands showing former presence of Betula nana

Abstract

Introduction. The Geological Survey of Denmark (D.G.U.) has taken up systematic studies on che vegetational history
of the Faroe Islands. This paper gives one of tlhe first results, namely the fact that Betula nana, which to day is absent from
the islands — as all other birches — has been growing there earlier. At Hoydalar, Streymoy, a boring ihas been made and
analyses of the lowermost samples in tlhe profile have clearly proved che existence of Betula nana.
