Biomass and Soil Properties of Fragmented Amazonian Forests

1997 to 2001 data from the Biological Dynamics of Forest Fragments Project (BDFFP) study area north of Manaus, Brazil. This dataset provides plot-level summaries of aboveground dry biomass, productivity, and soil characteristics for 50 one-hectare plots in undisturbed and fragmented central Amazonian rainforest. It is managed by NASA and consists of six comma-separated files.

Use Cases

• Modeling carbon stocks in fragmented tropical landscapes using aboveground dry biomass estimates.
• Analyzing the relationship between forest fragmentation and soil chemical/physical properties.
• Calculating above-ground productivity trends from repeated biomass surveys.
• Assessing the impact of land-use change on Amazonian forest structure and function.

Strengths

• Data is derived from detailed plant and soil samples across 50 standardized 1-hectare plots.
• Covers a 1,000 km2 experimentally fragmented landscape, providing a controlled study context.
• Includes repeated surveys enabling productivity calculations over a multi-year period (1997-2001).

Limitations

• Exact row counts, column names, and file sizes are not provided by any source.
• Conflicting last updated dates: NASA Earthdata lists 2001-05-05, while Data.gov lists 2026-03-13, suggesting metadata inconsistency.
