Mapeamento e avaliação de danos ambientais em castanheiras no sul do Amapá

Abstract

The mapping facilitates the planning of collection activities and the control of the annual production of each tree of the species (Bertholletia excelsa Bonpl.), in addition to being a condition for the licensing of management, with the competent agency. The present work aimed to map and evaluate damage to Brazil nut trees in an area under forest management in the municipality of Laranjal do Jari-AP. In mapping the Brazil nut trees, field campaigns were carried out in the forest management area with the help of company employees to locate the trees of the species. Field sheets were used to assess damage to the remaining trees, data collection within the forest was used a table with codes that classifies damage to the crowns and trunks, to assess the trees. In Amapá state, there is a high rate of Brazil nut stands, which makes it important to monitor them so that we can control/mitigate damage caused by felling, cutting, and other anthropic and natural factors that harm the conservation of the Brazil nut tree. 165 trees of the species were evaluated, in which damage to the crowns, cause of damage to the crowns, damage to the stems, cause of damage to the stems and tree health were evaluated. Low amounts of damage were observed, the area was minimally impacted with regard to trees of the evaluated species.
