Use, Perception, and Local Management of Copernicia Prunifera (Miller) H. E. Moore in Rural Communities in the Brazilian Savanna
Abstract Background Copernicia prunifera is a species native to the northeastern region of Brazil and is economically important as a source of income for many human populations in the region that carry out intense extractive activity on the species. This study aimed to evaluate the uses, management, and perception of the species by local extractors. Methods Two communities were studied, Bem Quer, where 15 extractors were interviewed, and Cana, where 21 extractors considered specialists were interviewed, totaling a sample of 36 informants. A regression analysis was used to explore the relationships between social variables (age, time in extractive activity, and income obtained from extraction) with the number of leaves exploited. The relationship between time of extraction, and time of residence in the community was also analyzed. Results The leaf was indicated as the most used part, from which an important powder is extracted for the production of wax. In addition, the leaf was also indicated for fertilization and construction. Uses were also indicated for the stem (construction) and fruit (forage). The relationship between the socioeconomic variables, income obtained through extraction and the amount of leaves extracted (in thousands) was significant (R2 = 0.73 and p < 0.001). However, the other variables analyzed in this study, such as the time spent extracting leaves and the amount of time residing in the community (R2 = 0.03 and p > 0.05), the number of leaves extracted and the age of informants (R2 = 0.05 and p > 0.05) and number of leaves extracted and time of extraction (R2 = 0.04 and p > 0.05) did not indicate a relationship. Conclusion C. prunifera was had a great economic and cultural importance for studied communities. It is possible that the economic factor is the preponderant force that directs the management strategies of native species.
