Tree Ring Width Chronologies for Four Pinaceae Species in Yakutia

Yakutia in Siberia hosts this collection of tree ring width chronologies for four boreal forest species: Larix gmelinii, Picea obovata, Pinus sylvestris, and Pinus sibirica. The data was collected during fieldwork in 2018 by scientists from the Alfred Wegener Institute, University of Potsdam, and Russian research institutes. Samples were processed into site chronologies using cross-dating techniques.

Use Cases

• Analyzing historical climate signals based on tree ring width chronologies.
• Studying species-specific growth patterns in boreal forests based on the four Pinaceae species.
• Cross-dating and validating dendrochronological records based on the described methodology.
• Correlating tree growth data with other environmental datasets linked in the description.

Strengths

• Data is linked to related datasets on tree height, crown diameter, and biomass, providing a broader ecological context.
• Specific geographic coordinates are provided for sample collection sites, enabling spatial analysis.
• The dataset is derived from a multi-institutional scientific expedition, suggesting rigorous collection methods.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Last update date is unknown; freshness unverified.
