Fourteen-region phytolith/charcoal synthesis: little to no intensive-use signal in most sampled terra firme
- what the source states
- The cumulative program's regional sequences "particularly in interfluvial areas showed a dominance of diverse, often closed-canopy forests with little to no evidence for annual crop plants or significant forest clearings and few signs of persistent forest burning during the pre-Columbian era" — summarized as "little to no evidence for: 1) agriculture with annual seed and root crops, 2) significant forest clearing, 3) anthropic soils, 4) human enrichment of favored tree taxa such as palms, or 5) recurrent/extensive fires."
- limitations
- New fieldwork covers three regions; fourteen is the cumulative synthesis.
- Soil-core sampling is spatially sparse; negative signals count only where the proxy could detect the activity.
