Abstract

In the new lichenometric curve which was constructed for the Polish section of the Tatra and Karkonosze Mountains, the thallus growth curve for the first 100 years was defined in a linear manner in relation to altitude. Therefore the curve can be easily used for dating items located in any part of the altitude zone for which the curve was defined. The paper also tackles the problem regarding the number of thalli that should be assessed when dating. An approach which assesses a certain number of the largest thalli of a similar diameter seems to be the most suitable for small-scale landforms (with small numbers of thalli) which were formed during one event. The shape of the thallus growth curve is strongly influenced by the landforms (either convex or concave) and the vertical extent of the zone in which the measurement is performed. The presence of multiannual snow patches in close proximity and air pollution also influence thallus growth on the mountains investigated
