Chronologies compiled at the Dendrochronological Laboratory
Publications by the staff of the Dendrochronological Laboratory

The Dendrochronological Laboratory of the Institute of Latvian History is at present the only scientific unit in Latvia engaged in dendrochronological dating of timbers mainly deriving from historical structures preserved in the territory of Latvia and compiling long absolute tree-ring chronologies. The majority of the historical wooden structures dated so far have been discovered in the course of archaeological excavation (mainly in Old Riga, as well as Cēsis, Jelgava, Ventspils, Krustpils and Āraiši). The remaining dated structures are preserved in architectural monuments in Old Riga, Āraiši, Bauska, Cēsis, Gaujiena, Turaida and Ventspils. Among the dated historical features are various wooden structures of historical residential buildings and churches, former revetments of riverbanks and slopes, wooden water pipe systems and street surfaces of logs as well as timbers from the base of the Riga city earthworks. An attempt has also been made to date a shipwreck washed up on the beach.

The absolute tree-ring chronologies compiled presently cover the whole of the second millennium AD (early 11th to late 20th century). These are mainly pine chronologies, with some spruce chronologies. Up to the second half of 2012, oak timbers from historic structures have not been dated, since they occur rarely.

The Dendrochronological Latboratory maintains close contacts with various dendrochronological laboratories in other European countries. Particularly important for the dating of exported timber and timber floated from a long distance away has been cooperation with colleagues in Estonia, Lithuania, Belarus, Denmark, Germany, the Netherlands and the United Kingdom. Questions relating to the history of the wood trade and wood export at the European scale during the previous centuries have been studies in collaboration with researchers from several other European countries, such as Russia, Poland, Austria and Belgium. Practical work has begun on the processing of dendrochronological information obtained by the laboratory for inclusion in an international database (Netherlands).

In the period 2005-2008, in collaboration with the Faculty of Biology of the University of Latvia, and partly also the Faculty of Geography and Earth Sciences, the Dendrochronological Laboratory has undertaken a small-scale basic research project "Dendroclimatological research in Latvia". This project has provided evidence of the impact of climatic factors on the radial growth of pine in the territory of Latvia at the present day, and it is planned to apply these findings in a further dendroclimatological study, aimed at obtaining more precise information about past weather conditions in Latvia.
