Hydraulic Traits of 16 Tallest Amazonian Trees, November 2024

14 standardized hydraulic traits measured on 16 Dinizia excelsa trees ranging from 19.7 to 74 meters tall in Brazil's Tumucumaque Mountains National Park. The data were collected during a single November 2024 field campaign to test if tree height influences drought vulnerability. This dataset is curated by the Environmental Information Data Centre and is embargoed until September 30, 2027.

Use Cases

• Modeling drought vulnerability based on tree height and hydraulic trait measurements.
• Analyzing trait variation within a single canopy across different sampling positions.
• Studying the functional ecology of a dominant tropical tree species, Dinizia excelsa.
• Benchmarking hydraulic trait data collected using standardized field methodologies.

Strengths

• Data collection followed standardized methodologies for each of the 14 traits.
• Measurements were taken from specific canopy positions (top, lower, branch) on 16 individual trees.
• All data originates from a single, controlled field campaign in November 2024.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• The dataset is limited to 16 trees from one location, which may affect generalizability.
• Row count is unknown, which may limit suitability assessment for large-scale modeling.
