Web site: Terrestrial/Plants – Government of South Georgia & the South Sandwich Islands . 3 October 2019 . South Georgia is home to just 25 species of native vascular plant, none of which are endemic. The poorly developed vascular plant flora is probably as a consequence of the island’s isolation from major landmasses and the relatively harsh year-round climate. In contrast there are around 125 species of moss, 85 liverworts and more than 200 species of lichen..
