Abstract Copaifera oleoresin is an important traditional non-timber forest product in the Amazon; however, the Carajás National Forest has no plans to harvest this product to benefit extractive families. The objective of this study was to determine Copaifera oleoresin extraction potential in the Carajás National Forest, Eastern Amazon, identifying variables that could increase the chances of finding oleoresin. We mapped 129 trees and formulated a multiple logistic regression model (logit) with the collected variables: diameter at breast height (DBH), tree crown, tree health, presence of termites, and presence of damage or bifurcation. Among the mapped trees, we perforated 50 trees to harvest the oleoresin. Most of the oleoresin production occurred in trees with a DBH between 50 and 75 cm. The logit model predicted that an increase in DBH, dense crown, unhollowed trunk, and presence of damage or bifurcation increased the chances of oleoresin extraction, whereas termites did not. The model could contribute to the sustainable management of forest resources by avoiding random perforation of trees and establishing rational routes and cycles of extraction. Since the variables are easily measured, the model can be continuously used for future extractions. Keywords Sustainability · Logit · Non-timber forest product · Forest management
1 Introduction Carajás National Forest is a Conservation Unit in the Eastern Amazon comprising approximately 4,119 km2 of three municipalities created in 1998 (ICMBio 2016). Conservation Units in Brazil fall into two main groups according to Brazilian Federal Law, number 9985/2000, Sistema Nacional de Unidades de Conservação da Natureza (SNUC): Integral Protection, whose purpose is to protect nature from human interference (indirect use of natural resources), and Sustainable Use, which allows the direct use of natural resources * Marcos Rodrigues [email protected] Extended author information available on the last page of the article

for the development of economic activities while respecting the environment, biodiversity, and natural resources. Carajás National Forest is classified as Sustainable Use and has a concession for mining as its main economic activity in addition to the exploitation of non-timber forest products (NTFP) by traditional communities and ecological tourism as described activities in the Conservation Unit’s management plan (ICMBio 2016). Although mining plays a major role in the economic development of the region (Matlaba et al. 2017), it has several negative externalities such as an increase in deforestation, including both
