Significance of Hippophae rhamnoides L. in evolution of the Eemian Interglacial' flora in Warsaw area

Krzysztof M. Krupiński

Abstract


Palynologic studies of sediments from Warsaw-Wawrzyszew and other sites in the Warsaw Basin enabled to analyze main occurrence phases of Hippophae rhamnoides during the widely understood Lake Pleistocene interglacial warming. In initial phases of the Eemian Interglacial (late glacial of a preceding glaciation) the area of Warsaw-Wawrzyszew indicated especially favourable conditions for such rich development of sea-buckthorn. Analysis of occurrence phases of this bush proves that besides climatic conditions, great influence on more abundant occurrence of sea-buckthorn in its late glacial (pre-interglacial) part could be played by edaphic conditions, mainly contents of basic compounds (CaCO3) in a substrate.
