Brazil nut is considered a model non-timber product for promoting conservation through use. Demographic studies, however, have demonstrated differential impacts of nut harvest on Brazil nut population structure. Comparing three populations with different forest use histories, degrees of road access, and recent levels of nut harvest, we asked: (1) Are they exhibiting regeneration failure? and (2) Are seedling/sapling densities explained by adult Brazil nut structure, fruit fate and/or overall forest structure?openAccessCastanha do brasilProduto florestal não madeireiro (PFNM)Manejo florestalReserva extrativistaExtractive reserveReserva extractivaSilvicultura sustentableRegeneración naturalProductos forestales no madererosNuez del BrasilCastanha do paráBertholletia excelsaRegeneração naturalBrazil nutsNontimber forest productsSustainable forestryNatural regenerationArtigo de periódico
