Litterfall Production Across a Forest Disturbance Gradient in Eastern Amazonia

Twenty 250 x 10 meter plots in the Brazilian Amazon provide litterfall measurements from January 2015 to October 2018. Study plots represent a gradient of forest disturbance, including undisturbed primary, logged, logged-and-burned primary, and secondary forests. Eight plots were affected by understory fires during an El Niño-mediated drought in December 2015, enabling analysis of fire impacts on forest productivity.

Use Cases

• [Modeling post-disturbance carbon flux] based on litterfall measurements across logged, burned, and secondary forest plots
• [Assessing El Niño drought impacts] based on the timing of understory fires in December 2015
• [Comparing ecosystem resilience] based on data from undisturbed primary forests versus human-modified forests
• [Analyzing temporal trends in forest productivity] based on data collected over a nearly four-year period

Strengths

• Provides a controlled spatial design with 20 study plots distributed across a defined disturbance gradient
• Captures a specific climatic event, with eight plots affected by understory fires during the 2015 El Niño drought
• Offers a multi-year temporal perspective with data collection spanning from January 2015 to October 2018

Limitations

• Key metadata such as specific column names, row count, file size, and license are missing from all platform entries
• The exact data collection methodology and measurement units are not described in the provided metadata
• The last update date (2026-04-16) from one source is in the future, suggesting a potential metadata error or placeholder value
