VAPU Dataset: Tree Biomass and Structure for Scots Pine and Norway Spruce in Finland

The VAPU dataset contains biomass and structural measurements for 162 Scots pine and 163 Norway spruce trees collected in southern Finland between 1988 and 1990 by the Finnish Forest Research Institute. Data sheets for pine and spruce match sample branch measurements with biomass information by cluster and tree number. Biomass estimation methods for foliage and branches are detailed in published scientific papers.

Use Cases

• Modeling age-related changes in tree biomass allocation based on species-specific measurements.
• Estimating carbon stocks in boreal forests based on tree-level biomass data.
• Developing allometric equations for Scots pine and Norway spruce based on branch and foliage measurements.
• Analyzing the relationship between tree structure and age for ecological modeling.

Strengths

• Contains measurements for 325 individual trees (162 Scots pine, 163 Norway spruce).
• Data collection was conducted by a national research institute (Finnish Forest Research Institute).
• Biomass estimation methods are peer-reviewed and published.

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.
