Brazil nut fruits fall to the ground in December through February when extractivists work almost exclusively in the collection and opening of these fruits to release the commercially valuable seeds or nuts. Based on income generated and labor utilized, this is the most important non-timber forest product activity in the state. Nonetheless, little is known about collection impacts on population structure. This study evaluated Brazil nut population structure in three traditional rubber tapper estates (sites) located in the municipalities of Xapuri and Brasiléia where the species occurs naturally: Filipinas, Cachoeira, and São Francisco Figueiredo.  aBrazil nuts  aPopulation dynamics  aBertholletia Excelsa  aCastanha do Para  aDinâmica Populacional  aAcre  aAcre River Valley  aAmazonia Occidental  aAmazônia Ocidental  aBrasiléia (AC)  aCastanha do brasil  aDinámica poblacional  aNuez del Brasil  aSeringal Cachoeira  aSeringal Filipinas  aSeringal São Francisco Figueiredo  aVale do rio Acre  aWestern Amazon  aXapuri (AC)1 aWADT, L.
