  abstract = {{B}razil nut, the {B}ertholletia excelsa seed, is one of the most important non-timber forest products in the {A}mazon {F}orest and the livelihoods of thousands of traditional {A}mazonian families depend on its commercialization. {B}. excelsa has been frequently cited as an indicator of anthropogenic forests and there is strong evidence that past human management has significantly contributed to its present distribution across the {A}mazon, suggesting that low levels of harvesting may play a positive role in {B}. excelsa recruitment. {H}ere, we evaluate the effects of {B}razil nut harvesting by the {K}ayapo {I}ndigenous people of southeastern {A}mazonia on seedling recruitment in 20 {B}. excelsa groves subjected to different harvesting intensities, and investigated if management by harvesters influences patterns of {B}. excelsa distribution. {T}he number of years of low-intensity {B}razil nut harvesting by the {K}ayapo over the past two decades was positively related to {B}. excelsa seedling density in groves. {O}ne of the mechanisms behind the higher seedling density in harvested sites seems to be seed dispersal by harvesters along trails. {T}he {K}ayapo also intentionally plant {B}. excelsa seeds and seedlings across their territories. {O}ur results show not only that low-intensity {B}razil nut harvesting by the {K}ayapo people does not reduce recruitment of seedlings, but that harvesting and/or associated activities conducted by traditional harvesters may benefit {B}. excelsa beyond grove borders. {O}ur study supports the hypothesis that {B}. excelsa dispersal throughout the {A}mazon was, at least in part, influenced by indigenous groups, and strongly suggests that current human management contributes to the maintenance and formation of {B}. excelsa groves. {W}e suggest that changes in {B}razil nut management practices by traditional people to prevent harvesting impacts may be unnecessary and even counterproductive in many areas, and should be carefully evaluated before implementation.},
