Title:	Brazil nut fruit production and growth from two sites in Acre, Brazil 2010-2019
Alternate Identifier:	DOI PLACE HOLDER
Abstract:	Data on fruit production and diameter were collected annually from a stratified sample of 129 Bertholletia excelsa trees in each of two extractive reserves. The large, canopy-emergent B. excelsa is a cornerstone of the Amazonian extractive economy, supporting a multimillion-dollar commodity crop (Brazil nut), which is harvested almost exclusively from old-growth terra firme forests. The same sampling protocols were followed in the two reserves, Filipinas and Cachoeira, located in Acre, Brazil, which have similar climate and forest types. The objective of the project was to assess the drivers of production at a tree- and site-level using data from 2010-2015 and 2016-2019. Tree-level data included information on tree crown size and form, as well as competition from neighboring trees. These data have been supplemented by publicly available observations of climate to assess the relative effects of individual tree and site-level factors, as well as climatic variability, on long-term productivity of this economically and ecologically important long-lived tree.

Description:

Fruit production was observed annually by counting fruits on the ground, which fall synchronically at the start of the wet season (~February). The samples of reproductively mature trees were selected in a stratified manner, to ensure a representation of tree sizes. Brazil nut trees in the two study sites naturally occur at densities of 1.35-1.82 trees per ha, and trees with overlapping crowns were excluded from selection so that fruit fall could be unambiguously attributed to a single tree. Tree diameter at breast height (1.3 m above ground level; DBH) was assessed annually. Three crown attributes of each sample tree were assessed once during the study: (1) Crown position was categorized as (a) Dominant (full overhead and side light), (b) Co-dominant (full overhead light), and (c) Intermediate (some overhead or side light) or (d) Suppressed (no direct light); (2) Crown size (m²) was estimated from radii measured in four cardinal directions for trees with regular crowns, and with 8 cardinal directions for trees with irregular crowns, using an ellipsoid formula; and (3) Crown form was categorized as: (a) Good, (b) Tolerable, or (c) Poor. Using a high-accuracy geodesic GPS unit, tree location and elevation were also noted. Competition from neighboring trees was evaluated in 2018, using the Bitterlich method, whereby competing trees were selected through evaluation of their size and distance from each subject (B. excelsa) tree. Using a prism with a 2.3 m²/ha basal area factor, we measured the DBH of all competing trees. For each tree, we calculated the basal area and number of competitors >30 cm DBH. In 2010, sapwood data were collected using a standard 5-mm increment borer at 1.3 m height, extracting two perpendicular cores ~150mm in length per tree. Each core was visually cross-dated, and the sapwood area (cm²) was calculated.

Description:

• The Filipinas study site was located in one unlogged 420-ha extractivist landholding in the southeastern portion of Extractive Reserve Chico Mendes (Colocação Rio de Janeiro in Seringal Filipinas). The Reserve maintains 92% forest cover. Filipinas is dominated by open forest with bamboo and/or palms, with a small area classified as dense forest 2. Our second study site was located in the Chico Mendes Agro-Extractive Settlement Project (informally known as Cachoeira), which maintains 90% forest cover. This site shares similar forest types as Filipinas, but in different proportions. Cachoeira is dominated by dense forest with a smaller area classified as open forest with bamboo and/or palms
