Abstract

The Budapest Tree-Ring Laboratory (BTRL) is a fully equipped dendrochronological laboratory, established in 2002 at the Department of Paleontology and currently hosted by the Department of Physical Geography, Eötvös University, Budapest, Hungary. The lab has the proper sampling equipment for field work, a sanding workshop to prepare tree-ring samples for measurement and measuring-stages with software for recording and analyzing tree-ring data. Throughout the first 20 years of activity the BTRL collected and analyzed ∼360 living and ∼470 relict samples (including historical and subfossil material) from more than 33 sites distributed mainly in Europe but including a few localities in Asia. The most represented genera are Quercus and Pinus, both among the living and the relic subsets. Open access publication of the essential ancillary scientific information of the stored material will make the sample archive of the BTRL an actual national research infrastructure.
