Hyytiälä SMEAR II: Pre- and Post-Thinning Forest and Carbon Inventory

Twenty-four measurement plots at the SMEAR II research station in Hyytiälä, Finland, provide detailed forest and carbon stock data before and after a thinning operation. The dataset includes tree-wise inventory data, plot-level forest characteristics, carbon stock calculations, and a plot map. It is intended for analyzing the impacts of forest management on carbon sequestration and stand structure in a boreal forest.

Use Cases

• Quantifying carbon stock changes due to thinning based on plot-level carbon stock files
• Modeling forest growth and yield using tree size distribution and plot measurement data
• Assessing silvicultural treatment impacts by comparing pre- and post-thinning forest characteristics
• Spatial analysis of forest structure using the provided plot map geospatial data

Strengths

• Includes detailed, cleaned tree-wise inventory data for 24 measurement plots
• Provides both pre- and post-thinning measurements, enabling direct impact analysis
• Contains supporting documentation including methodological descriptions and calculation equations

Limitations

• Key metadata such as row count, file size, and specific update date are unavailable across all sources
• The dataset's temporal coverage is ambiguous, referencing both 2019 and 2020 measurement results
• Column names and a complete data dictionary are not provided in the available descriptions
