Summary: Brazil nut (Bertholletia excelsa H.B.K.) is a long-lived emergent, distributed throughout much of the Amazon?s terra firme forests, and lianas that climb this forest dominant are in a superior position for accessing light. However, traditional ecological knowledge expressed by local extractivists asserts that lianas negatively impact Brazil nut yield. We investigated Brazil nut-liana relations in a 420 ha forest located in Extractive Reserve Chico Mendes in the Western Brazilian Amazon. Our objectives were twofold: (1) To determine the relationship between Brazil nut crown vine loads and vine origin, number, and basal area; and (2) To determine the relationship between vine loads and Brazil nut tree fruit and nut yield, diameter growth, and crown form, position and area.
