Human impact on an island ecosystem:pollen data from Sandoy, Faroe Islands
Aim To investigate the form and dynamics of ecosystems on an isolated island in the North Atlantic before human settlement in the first millennium AD, and the effects of human activities thereafter. Location The island of Sandoy, Faroes (61°50' N, 6°45' W). Methods Two sequences of lake se...

Aim To investigate the form and dynamics of ecosystems on an isolated island in the North Atlantic before human settlement in the first millennium AD, and the effects of human activities thereafter. Location The island of Sandoy, Faroes (61°50' N, 6°45' W). Methods Two sequences of lake sediments and one of peat were studied using pollen analysis and sedimentological techniques. Age models were constructed on the basis of radiocarbon dating and, in one case, tephrochronology. The data were analysed statistically and compared with existing data from the region.
