Title of the project:
Holocene climatic changes reflected in arboreal vegetation succession, tree-limit and fire history in Finnish Lapland

2.summary of work performed and results

The aim of this study was to carry out anthracological examinations on Holocene charcoal samples derived from Finnish Lapland.

This research is supported by a Marie Curie Fellowship of the European Community programme “Improving the Human Research Potential and the Socio-Economic Knowledge Base” under contract number “HPMF-CT-2002-01728”.

Description of the research project

The sites around sand dunes of Lapland containing charcoal layers are the followings: 1. Iijärvi, 2. Kiellajoki, 3. Mutusjärvi, 4. Hietatievat, 5. Pasmajärvi, 6. Pöyrisjärvi, 7. Palojärvi, 8. Kuttanen (Seppälä, 1995), in order from East to the West along the polar tree limit in Northernmost Finland. Hietatievat (Seppälä, 1974; van Vliet-Lanoë et al., 1993) and Kuttanen (Seppälä, 1981) are esker-dune regions, with several, sometimes up to 35 charcoal layers in one exposure. All sites have several exposures.

The aim of this study is to carry out anthracological examinations on the samples from the different layers of the sites mentioned above. That would mean:

-collection of new samples from the sites according to fine-stratigraphy and anthracological (Vernet, ed., 1992) methods;

-application of pedoanthracological methods in the examination of the collected samples – this allow us to draw conclusions on former forest density, then density changes in the different ages, thus on climatic factors;

-tree species identification on the charcoal pieces using xylotomy – forest type succession – follow forest oscillations in time;

-comparing the results from the different sites at the different ages – forest oscillations in space;

-tree age determination on the basis of xylotomy – forest age determination;

-application of derivatography– conclusions on fires;

-new datings to be done on the same samples;

-possible correlation of layers of the different sites with layers of other sites and events reconstructed with other types of Quaternary methods;

-comparing the results to Hungarian Pleistocene finds: both seems to have faced discontinuous permafrost with boreal forests.

There are also old charcoal samples at the Department of Geography, University of Helsinki, which had already been radiocarbon dated. It is also important to examine these samples as descripted above.

Examinations in the SEM lab would concern charcoal, namely examination of charcoal sample surfaces under SEM to make histological identifications of the samples.

Sample size varying between 1-2 cm – 5 mm of charcoal cubes.

Due to the different time-scale of the scholarship as a result of the delay of the beginning of the granted period the project plan could not be fully evaluated.

During the three months from the granted seven I just started the project. First of all I started with collecting and reading the literature concerning the subject, namely to get acquainted with the sites, their geography, vegetation and Holocene history known so far. The University of Helsinki proved to be an excellent place to get all the papers I needed, as lots of works can be found directly by the internet. It was a marvellous experience that I can download full text papers from the net thanks to the overall subscriptions that the University has. Where there is no electronic version available I could find all the papers and books in the neighbouring library, or in other libraries of the University.

Detailed geomorphological investigations were carried out on sand dunes in Finnish Lapland dealing with deflation and redeposition of sand in order to study the possible causes and mechanism of sand movements and desertification (Seppälä 1974, 1981, 1984, 1995; van Vliet-Lanoë et al. 1993; Filion 1984; Mann et al. 2002). During the fieldwork of these investigations several charcoal layers with extremely high amount of fossil material came to light from buried palaeosols, which are very common in Finnish Lapland.

Palinological investigations were carried out, as well, from surrounding peat bogs (Carpelan, Hicks 1995; Eronen et al. (eds.) 1993; Hicks 1975, 1985, 1992, 1993a, 1993b, 1994, 1995, 1999, 2001; Hicks, Hyvärinen 1999; Vuorela, Hicks 1996), but no arboreal vegetation reconstruction took place at all from these sites as no anthracology as a palaeoecological method was used here. As the charcoal remains in situ it allows us to examine the local former vegetation.

Studying Holocene climatic changes in the region and new palaeoclimatological methods are also needed to the planned reconstruction so I studied the literature concerning these subjects, as well (Bianchi, McCave 1999; Eronen et al. 1999; Falcon-Lang 2000; Jacoby et al. 2000; Korhola et al. 2000, 2002; Kullman 1995; MacDonald, et al. 2000; Pienitz, Vincent 2000; Seppä, Birks 2002; Stuiver et al. 1997; Waelbroeck et al. 2001; Wolfe et al. 2000) Biogeographical (Huntley, Webb 1989; Lavoie, Payette 1996) and anthracological issues were also concerned (Falcon-Lang 2000).

Charcoal samples are at the Department of Geography, University of Helsinki, waiting for anthracological examinations. The sites around sand dunes of Lapland containing charcoal layers are listed in the project plan, but due to the short time I started to work only on the Kaamasjoki-Kiellajoki area. Another problem emerged that fieldwork and collection of new samples would have been needed but due to the limited grant sum travelling to Lapland seemed to be impossible. I tried to travel with the supervisor, but he neither had suitable trips to the sites. There has also been a dating project on the charcoal layers with several data carried out in the University of Wales, Swansee by Prof. John Matthews. So I received charcoal samples from the radiocarbon lab, which have already been dated and some charcoal left, originating from the Kuttanen esker-dune region. Here the profiles are with several, sometimes up to 35 charcoal layers in one exposure. Although, complete examination of all of the samples from this site was not possible during the scholarship.

In the Physical Geography Laboratory at the Department of Geography of University of Helsinki, they provided me every facilities to the evaluation of the project.

I also intended to reveal the fire history of the area, also the possible causes and intensity of fires, and the effects of fires on deflation and desertification. Fire-climate relations would also be possible to trace. So I collected literature on the boreal forest fires, and forest fire dynamics, as well (Campbell, McAndrews 1995; Clark 1995; Clark, Royall 1995; Clark, et al. 1989; Rowe, Scotter 1973; Shugart et al. eds. 199; Siegert et al. 2001).

Possibility of tracing human action also appears.

Also the aim of this fellowship was to carry out botanical-vegetational investigations on the today forests of Finland – to be able to stand a model close enough for the Hungarian Pleistocene vegetational reconstructions. I started this part of the project as well, by collecting data on the present day botany of Finland.

Preparation of a reference collection of charred wood for Hungary for the Pleistocene interstadial vegetation identification also started with the collection of wood pieces from different species of the boreal forest zone.
