RESUMO:

The Amazon is the biome that holds the greatest planetary biodiversity. Among so many animal and plant species found in this biome, the Brazil nut tree stands out, belonging to the Lecythidaceae family. The aim of this study will be to investigate the population structure, dendrometric growth and the productivity of B. excelsa populations established in two management areas in the Tapajós National Forest (FLONA). The measurements and data for this research will come from two Annual Production Units (01 and 10), both located at km 117 of BR163. To assess the growth of the species over time, dendrometric data will be collected for two consecutive years, in addition to the measurements derived from previous inventories. Regarding mortality, the inventoried Brazil nut trees that have been found dead during data collection work in both areas will be noted. For the study of the productivity of the Brazil nut trees of UPAS 01 and 10, the number of fruits per trees, previously selected, will be counted. The methodology applied will be the counting of hedgehogs located on the forest floor in what comprises the tree canopy radius. In addition to counting the fruits, the circumference of 20 hedgehogs will be measured in each tree, counting the seeds present inside them, and also measuring all the almonds, in order to obtain data related to the morphometry of the fruits of B. excelsa. The minimum distance between trees selected for fruit production studies should be 50 meters in order to ensure that there are no risks of high kinship between them (sample independence). In addition, the study plans to collect data related to the entry of light in forest environments in order to prove the effects of forest management on the forest cover with LIDAR (Light Detection and Ranging) equipment and spherical densiometer. The differences in dendrometry growth, productivity, morphometry of hedgehogs and seeds, estimation of agouti activity and% of canopy coverage between the two areas will be tested with several means comparison tests. As there is still no collection of Brazil nuts in the forest management area of FLONA of Tapajos, the results of this study will serve as a subsidy to identify the most productive trees and their potential for collection based on accessibility and facility of production flow.
