Abstract

The aim of this paper is to report measurements made since 1981 of the growth rate of a very large lichen of the Rhizocarpon subgenus which, in 2007, had a maximum diameter of 465 mm, and to discuss the implications for lichen growth studies and lichenometric dating. Specific objectives are: (1) to estimate the extent of variability in the mean annual radial growth rate both around the thallus perimeter and through time; (2) to compare the growth rate with those of smaller lichens; and (3) to evaluate the implications of the results for lichen longevity, lichen growth-rate models and lichenometric dating curves
