Eemian organogenic deposits, analysed at the Struga and Parysów sites (Garwolin Plain, central Poland), reveal the vegetation history. Palynological analysis supported by plant macrofossil analysis revealed a pollen succession encompassing seven regional pollen assemblages zones, E1-E7 RPAZ, within which indicator taxa for various climate characteristics (mainly temperature and humidity, including Tilia tomentosa and Hedera helix) were recorded. Additionally, the Struga G-120 profile encompasses a Late Saalian section of deposits in which stadial and interstadial oscillations are inferred. The data corroborated earlier findings that the warmest and wettest part of the Eemian interglacial was during the hazel phase (E4 RPAZ) and the beginning of the hornbeam phase (E5 RPAZ). The younger part of the hornbeam phase bears the record of a decrease in humidity and gradual drop in air temperature. During the telocratic period encompassing the spruce-fir (E6 RPAZ) and pine (E7 RPAZ) phases, increased humidity and rising water levels in the lakes studied are again evident. The reconstructed plant succession and climatic conditions are discussed against a broader background of other Eemian profiles from Poland and neighbouring countries. They largely confirm that, at that time, the Garwolin Plain showed characteristics typical of a transitional climate from oceanic in Western Europe to continental beyond the eastern borders of Poland.

The paper presents results of pollen analysis of organic sediments from the site Katowice 2. Six local pollen assemblage zones identified in the section represent the youngest part of Mazovian Interglacial. The pollen spectra of the basal part of the section display some changes indicative of intra-interglacial cooling, well recorded in many profiles of this interglacial in Poland. The forest landscape was subsequently dominated by hornbeam-fir communities which were replaced later by those of pine forests. In turn, taxa of thermophilous aquatic plants, represented by pollen Trapa and microsporangia Azolla filiculoides and Salvinia evidence of lacustrine environment. The results of pollen analysis of sediments from the Katowice site and those hitherto obtained from some other localities in western and central part of the Polish Uplands (Malice, Raków, Wielki Bór, Konieczki i Białe Ługi) became the basis for distinguishing seven regional pollen zones for this area. As compared to pollen succession from Podlasie and eastern Poland, the most significant differences concern the course of pollen curves of Carpinus and Abies and the sequence of their pollen culmination.

The paper shows results of pollen analysis of organic sediments from the site Malice (M1). The diagram includes 11 local pollen zones representing Mazovian Interglacial. Forest landscape in the vicinity of the site has changed together with the climate amelioration. In the beginning of the interglacial, birch and pine forests predominated in this area. Later, they were replaced by alder, spruce and yew communities, and next by multispecies deciduous forests and fir woods. Warm and humid climate of this interglacial is indicated for instance by high percentage of Taxus pollen (49%). According to Janczyk-Kopikowa, 1991 at the beginning of the pollen period III the pollen curves show that an intrainterglacial climate cooling might have taken place what has also been recorded in many pollen diagrams of this interglacial in Poland. Pollen succession from Malice, apart from features characteristic for the succession of Mazovian Interglacial, also shows many local features caused by differentiation of habitats, and various hydrological and microclimatic conditions. Similar features are also revealed from the succession at the site Konieczki located nearby. Despite the fact that the influence of oceanic climate in Mazovian Interglacial reached farther eastwards than it is now, the forest landscape of Poland was also regionally differentiated, although not as distinctly as it is today.

This paper presents the results of palaeobotanical studies (pollen and plant macrofossil analyses) of the sediments from the profile Michałowo P-3 (Gródek-Michałowo Depression, NE Poland). At this profile the second bed of peat under Holocene peat and the layer of silts and sands was discovered. The pollen succession indicates that it were deposited, with some gaps, from the beginning of Eemian Interglacial to Early Vistulian. The local pollen zones, distinguished in the Pollen diagram, correlate with the regional pollen stratigraphy of the Eemian Interglacial, but the pollen record of hornbeam (E5 R PAZ) and spruce (E6 R PAZ) regional zones is absent in Michałowo. In the middle part of the Michałowo pine zone (Mi-5 Pinus L PAZ), a cool oscillation of climate is marked by an opening of forests and development of herb plant communities.
