Abstract

This study uses 9 reliably dated surfaces covering the last 270 years within southeast Iceland to construct a regional lichenometric dating curve. The growth of lichen species within Rhizocarpon Section Rhizocarpon is non-linear over time, with larger (older) thalli apparently growing more slowly. Reasons for the non-linearity of the new dating curve are probably physiological, although climatic change over the last 3 centuries cannot be ruled out. Use of linear growth curves in Iceland is problematic over time-spans of more than c.80 years
