Extractive activity of Euterpe oleracea Mart. (Acai palm tree) in the Araguari River Valley, Eastern Amazon

The acai palm tree is a species of multiple use and of great importance for the Amazonian economy and riverside families. The high appreciation of the acai berry in the national and international markets contributes to the search for new producing areas and the reduction of repressed demand. This research aimed to identify the knowledge of the riverside families about the acai berry extraction activity in the Araguari river valley. The study was between the municipalities of Ferreira Gomes and Cutias, in an extension of 80 kilometers. The properties were sampled according to the following criteria- i) presence of natural acai massifs; ii) acceptance of the research by the interviewee and iii) permission to implement sample plots. Data were obtained through a form and interviews with structured questions. Non-probabilistic sampling (n = 13) was used to select local extractivists who hold acai areas. The field research with extractivists allowed us to infer that the period of high fruit production extends from March to June. The use of byproducts of the acai is little expressive. Although livestock is the most expressive activity in the region, others stand out- fishing, agriculture and extractivism. The commercial production of acai fruit is destined to the municipality of Cutias and most native acai owners have significant interest in the management of this species.
