Coarse Woody Debris Measurements from Brazilian Old-Growth Forest

Measurements of standing and fallen coarse woody debris (necromass) were collected in an old-growth upland forest at the km 67 eddy flux tower site in Brazil's Tapajos National Forest. Data collection spanned from April 2001 through July 2001, with debris categorized into specific size classes measured across different plot scales. This dataset was produced by the National Aeronautics and Space Administration as part of the LBA-ECO project.

Use Cases

• Estimating necromass carbon stocks in old-growth tropical forests using the categorized size classes (2-10cm, 10-30cm, >30cm, standing).
• Analyzing the spatial distribution of coarse woody debris across different plot sizes (64 m², 1600 m², 38400 m², and 50m x 1000m transects).
• Calibrating remote sensing or ecological models for forest biomass with ground-truthed measurements from a primary forest tower site.
• Studying coarse woody debris dynamics and decomposition processes during the April-July 2001 observation period.

Strengths

• Data includes measurements across four distinct, ecologically relevant size classes of coarse woody debris.
• Measurements were taken at multiple spatial scales, from 64 m² subplots to large 50m by 1000m transects.
• Data originates from a well-defined, long-term ecological research site (km 67 tower site) within the Tapajos National Forest.

Limitations

• The exact row count, column names, and dataset size are not provided by any source.
• Sources conflict on the last update date, with datagov listing 2026-03-13 and nasa_earthdata listing 2001-07-15.
• The specific license is unclear, only described as 'other-license-specified'.
