Resumo: | ABSTRACT Amazonian peoples use and manage plant populations in previously domesticated landscapes, but the extent of landscape transformation remains uncertain, especially in interfluvial areas. We tested the hypothesis that useful plant communities vary in richness, abundance and basal area around pre-Columbian and current settlements independent of the distance to a major river. Nine plots were established at different distances from settlements in the Humaitá National Forest and the Jiahui Indigenous Land, where trees and palms with DBH ≥ 10 cm were sampled. Interviews were used to identify species, their uses and management practices. We found high values of richness, abundance and basal area of useful species around settlements both close to and 70 km from the major river. Different use categories presented different responses to current management, which shows that management by current and past populations is selective. We showed that areas of intensive management and landscape transformation are not limited to the margins of major rivers, but also occur in interfluvial areas within a radius of 5 km from pre-Columbian and current settlements. Indigenous people and local communities manage forests around their settlements over time, showing that they are key actors in the sustainable use of Amazonia.
