The vegetational history of Inaccessible Island, a remote uninhabited island in the Tristan da Cunha group, has been reconstructed by means of pollen analyses from two bogs. The first is on the plateau in an area today dominated by fern-bush; the second, Skua Bog, had formed in a hollow on the surface of a landslip near sea level and is surrounded by dense tussock grassland. The pollen analyses, reveal marked differences between the bogs, indicating that the broad composition of the vegetation surrounding each site has changed very little during the time these sediments accumulated. Diatom analyses have also been undertaken from these two sites. The diatom evidence from Skua Bog indicates an initial brackish influence that lessens upwards, reflecting stages of sedimentary infill and overgrowth. from Authors
