The aim of the project was to find precipitation sensitive trees in Eastern Austria and to perform a 500 year long reconstruction of precipitation sums. The black pine (Pinus nigra var. austriaca) is described in the literature as a precipitation sensitive tree and due to its high age (up to 700 years) it is possible to set up 500 year long reconstructions of precipitation totals in the area of the ŃThermenlinień in the eastern part of Austria. As there is only a small number of trees available in the early period we focus on the period from 1700 to 1995 AD. In addition the parameter "false rings" (or density deviations) was used to reconstruct the amount of precipitation in May. This reconstruction shows interesting results throughout the period from 1880 to 1995 AD especially regarding the interpretation of year rings.
