Phytohistorical aspects of the natura 2000 site "Maramureş Mountains".

This paper presents the results obtained through palynological analysis of a core sequence from the Cristina glacial cirque (Latitude 47°50'07''N, Longitude 24o37'07''E, altitude 1573 m). It is a relatively short sequence, reaching 300 cm in depth, but the first 145 cm could not be taken, as it consisted of wet and very loose peat. Three C 14 datings performed on samples taken from the analyzed sequence, at the Radiocarbon Laboratory in Poznan, Poland, have provided the following ages: Cr 250 - 6190 ± 40 BP; Cr 265 - 5200 ± 50 BP; Cr 300 - 7150 ± 40 BP. For the basal sample of the sequence the dating assigns an Atlantic age. Pollen spectrum analysis from the depth of 150 cm, not yet dated, suggests a Sub-Atlantic age, through the presence of beech and fir pollen.
