Amazon Tree Inventory with Biomass Calculations for Ducke Reserve

This dataset contains common names, base diameters, and calculated masses for nearly 3,000 trees within a 5-hectare plot in the Ducke Reserve near Manaus, Brazil. Measurements were collected during a single field campaign from October to December 1999. The data was compiled by the ORNL_CLOUD organization, providing a detailed snapshot of central Amazon forest structure.

Use Cases

• Estimating above-ground biomass and carbon storage using the calculated tree mass column.
• Analyzing forest structure through stem density and diameter class distribution derived from base diameter measurements.
• Studying taxonomic composition at the family or genus level using the common names of trees.

Strengths

• Provides a detailed census of nearly 3,000 individual trees within a standardized 5-hectare plot.
• Includes calculated tree mass, a key derived variable for biomass and carbon studies.
• Measurements follow a standardized protocol, with diameters taken at 1.3 meters height (DBH) or above anomalies.

Limitations

• The dataset is a single snapshot from late 1999, offering no temporal trend analysis.
• Specific column names and the complete data file structure are not described in the provided metadata.
• There is a conflict in the 'last updated' field between platforms (1999 vs. 2026), suggesting potential metadata inconsistency.
