Brazilian Forest DBH and Species Data from Burned and Unburned Sites

Four forest sites in eastern Acre, Brazil, provide diameter at breast height (DBH) measurements and species identification for trees. NASA collected this inventory data in October and December 2017 across locations burned in 2005 and 2010, as well as nearby unburned control areas. The dataset supports analysis of post-fire forest structure and composition.

Use Cases

• Analyzing changes in tree diameter distribution between burned and unburned forest plots.
• Comparing species composition and richness in areas affected by fires of different years (2005 vs. 2010).
• Modeling forest recovery and structural resilience following wildfire disturbances.
• Ground-truthing remote sensing estimates of forest biomass or damage in the Brazilian Amazon.

Strengths

• Data includes a controlled comparison across four distinct sites with both burned and unburned conditions.
• Surveys provide specific temporal context, conducted during two months in late 2017.
• Inventory covers forests impacted by fires in two separate years (2005 and 2010), allowing for temporal analysis of recovery.

Limitations

• Exact row count, file size, and complete column schema are unknown across all sources.
• Conflicting last update dates exist between platforms (2017 vs. 2026), suggesting potential metadata inconsistency.
• License is ambiguously listed as 'other-license-specified', requiring further investigation for reuse terms.
