Dendrochronologic dating and age calculation of old wooden items with the help of rings. Every summer a new ring appears in trees. A "good" summer will see a thick ring, and a "bad" summer will see a thin ring. This happens similarly over relatively large, uniform areas. This can be used to put together a medium curve that shows how the growth of trees has varied within an area, f.e north Dalarna.

- Our ambition is to date buildings, historical items as well as archaeological and forest-historical finds. By collaborating with country administrative boards, museums, local heritage associations and private people, we wish to create interest and point out the importance of the cultural inheritance the old buildings and items constitute.

With the help of successively older overlapping trees the curve can be extended back in time. The age of the ring farthest out in living trees is known, therefore all the other rings can be calculated as well.

The work with describing dendrochronological base curves in Norrland began over 20 years ago in north Lapland. The activity continued through the years and in the end of the 1990s resulted in one of the worlds longest dendrochronological series, the so-called Torneträskserie, which reaches 7400 years back in time. Therefore it covers the larger part of the time after the latest ice age. As a result of this research DendroLab was founded in 1999. DendroLab has activities in Lycksele, Sollerön and research in Abisko.

Please contact us if you have any questions regarding analysing etc. We can also mediate datings of objects in southern Sweden.
