“…2.2). These dates show good agreement with results of regional studies (Amon et al 2014;Veski et al 2012) and support the idea of relatively rapid ice retreat from the eastern Baltic. Moderately higher OM and lower MS values indicate changes in vicinity corresponding to the warmer period (Allerød) (Lowe et al 2008) at the end of GI-1 (Fig.…”

“…One such factor is the vegetation colonisation period. Previous studies have shown that the colonisation of pioneer vegetation took only a few decades after the land became ice-free (Jones & Henry, 2003;Heikkilä et al, 2009;Amon et al, 2014), which is within the error limits of the AMS age determination. Another factor for terrestrial floral development is connected with palaeohydrology and landscape.…”

“…The local late-glacial minerogenic sediments contain very little, but sufficient, organic (terrestrial) material for AMS 14 C dating and palaeobotanical studies (e.g. Amon & Saarse, 2010;Amon et al, 2014). So far, the plant macrofossil data indicates that the late-glacial treeline was located in southern Estonia , but new sites in northern Estonia help to define the detailed dynamics of the treeless tundra.…”

In this study, the deglaciation chronology of the Pandivere Upland is defined, and the late-glacial vegetation trends of north-eastern Estonia are summarised. The multi-proxy study includes accelerated mass spectrometry 14 C dating, plant macrofossil, magnetic susceptibility, loss-on-ignition and grain-size distribution data of the lacustrine sediment record from one previously unpublished study site (Kursi), and the study discusses the results in combination with five previously published study locations from the area.The results indicate that the deglaciation of the Pandivere Upland started at approximately 14 200 cal. yr BP and was completed by 13 800 cal. yr BP. The ice recession rate was approximately 180 m yr -1 . Based on these new radiocarbon dates, the Baltic Ice Lake stage A 1 submerged the northern and western ice-free areas of Estonia by ca. 13 800 cal. yr BP. The prevalent vegetation type in north-eastern Estonia during the late-glacial period was tundra with local variations in the dominant shrub species. The region remained treeless until the Holocene.

“…The Lateglacial vegetation in Europe was dominated by herbaceous vegetation types with abundant Poaceae and Artemisia as well as scrublands with Juniperus and Betula nana and boreal woodlands with Pinus and Betula trees. During the Lateglacial the latitudinal tree line formed in central Europe (Theuerkauf & Joosten, 2012;Mortensen et al, 2014), and reached a more northerly position to the east of the Baltic Ice Lake (Amon et al, 2014). However, this tree line consisting of Pinus and Betula is not adequately represented in the maps (see methods) resulting in biases in their Lateglacial distribution.…”

Aim Palaeoecological reconstructions document past vegetation change, with estimates of fast shifts in species distributions. The resulting rates of plant spread are often not matched by model simulations of climate-driven vegetation dynamics. Genetic surveys of extant plant populations document directions of the post-glacial spread of trees, challenging traditional interpretations. Our aim is to examine an updated continental pollen data set from Europe in the light of the new ideas about vegetation dynamics emerging from genetic research and vegetation modelling studies.Location Europe.Methods We use pollen data from the European Pollen Database (EPD) to construct interpolated maps of pollen percentages documenting changes in the distribution and abundance of major plant genera and the grass family in Europe over the last 15,000 years. Main conclusions The calculated rates of post-glacial plant spread are higher in Europe than those from North America, which may be due to more rapid shifts in climate mediated by the Gulf Stream and westerly winds. Late Holocene anthropogenic land use practices in Europe had major effects on individual taxa, which in combination with climate change contributed to shifts in areas of abundance and dominance. The high rates of spread calculated from the European pollen data are consistent with rapid tracking of early Holocene climate change by common tree species, documenting that plants can spread fast tracing their climate space, regardless of their dispersal strategy.
