Koenigia islandica has a disjunct Arctic-sub Arctic circumpolar distribution extending southwards to several isolated mountain ranges of northern Europe, Asia and North America. The population of this plant on the Isle of Skye (at altitude 461-726 m) and Isle of Mull at (385-523 m) was the most Southerly in Europe and therefore the most vulnerable likely to exhibit the impact of climatic fluctuations on numbers and survivorship. Koenigia was also an annual, which made it particularly vulnerable to adverse conditions and exhibited large fluctuations in number and survivorship between years. Mapping the precise position of colonies of Koenigia on island of Mull and Skye was done by geographical positioning systems (GPS).
