RESUMO:

The Tapajós National Forest, created in 1974, was designed to be a model in the sustainable use of natural resources. Currently has several research projects and multiple national and international partnerships, in the most diverse areas of knowledge. This study highlights the scientific production carried out in Tapajós Flona, focusing on the area of forest inventory, population structure of tree species and forest exploration. It aims to analyze scientific production, highlighting articles related to floristic composition and forest structure; analyze the census forest inventories conducted in the last 20 years in order to understand the structure of the main tree species of wood value; and to analyze the directional cutting of trees selected in the census inventories, as well as the occurrence of hollows. A bibliometric survey of all scientific articles produced on the theme of forest inventory conducted in the Flona do Tapajós, published from 1980 to 2020, will be indexed in the databases of Scopus SciVerse, Web of Science, SciELO (Scientific Electronic Library Online) and BDPA (Agricultural Research Database), to show the authors, the number of articles published and the journals that transmit these articles, to measure scientific production. The keywords used in the bibliographic research process were: “Floresta Nacional do Tapajós” and “Tapajós National Forest”. Based on bibliometric analysis, articles containing information on floristic composition and forest structure will be selected to be compared with data from census forest inventories, conducted by Flona's cooperative, which since 2005 manages the forest, to obtain wood, showing which tree species of wood value are present in all forest inventories carried out. The floristic composition will be analyzed based on the numbers of individuals, species, genera and families. Floristic diversity will be calculated using the Shannon-Wiener index and Pielou's equitability. The horizontal structure will be described by means of the abundance, dominance and frequency parameters, in addition to the importance value index (IVI) of the inventoried species. The evaluation of the directional felling of the trees selected in the census inventories will consider the angles of natural fall, planned fall, effective fall and fall of the crown and the time of execution, observed at the time of forest exploration. The external characteristics of the trees will also be observed, such as: presence and dimensions of the sapopemas, shape of the canopy, presence of vines, slopes of the bole and in the ground, damage to the remaining vegetation and the occurrence of hollows, which will assist in the assessment of the direction of fall of the trees, as well as in the evaluation of the occurrence of hollows. Hollow detection will be carried out by drilling with the chainsaw's saber tip, at a 90-degree angle to the tree trunk, at the time of the felling activity. The frequency of hollows will be related to the external characteristics of the trees. Bibliometric, structure and forestry analysis will contribute to a more detailed knowledge of the populations of the main tree species of wood value and how these species are being explored in the Tapajós Flona.
