Pollen Analyses of the Sediments of Plitvicka Jezera (Lakes of Plitvice)

In the area of the Lake of Plitvice two core holes were drilled to a depth of 8 m. Palynological analyses show Holocene forest vegetation, namely the climax Abieti-Fagetum . Initial postglacial forest phases which preceded the Abieti-Fagetum are not represented in the pollen diagram. Hence the conclusion can be drawn that the vegetation, as shown in the diagrams, starts as late as the end of the Boreal period, i. e. at bout 8000-7000 years B. P. The short-term dominance of Abies at the top of the diagrams may coincide with a similar rise of Abies at Ljubljansko barje, contemporary to Eneolithic settlement. At this time interval, 8000-4000 y. B. P. both pollen diagrams can be dated. Thereby also a direct indication is provided as to the time and the extent of the growth of the barrier and the rise of the water-level of Proscansko jezero.
