Dendrochronological research project.

The year in which the research stored in https://dataverse.nl/dataverse/stichtingring took place, from 1985 onwards can be found in the report number, with for example ‘P:1997001’ implying that this particular study took place in 1997. Interpretations of the most likely wood provenance and estimations of the number of missing sapwood rings, if included in the original research report, are based on the knowledge at the time and may be subject to later refinement.

Years: -789 to 444 (this is an approximate time interval; see the research report(s) in this dataset for the exact calendar years).
