Background Copernicia prunifera belongs to the Arecaceae family, and its production chain includes a set of economic activities based on the use of the stipe, petiole, fiber, fruits, roots, and leaves from which carnaúba wax is extracted, an economically valuable resource in the region. 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 of carnaúba leaves were interviewed, and Cana, where 21 extractors considered specialists were interviewed, totaling a sample of 36 interviewees. Interviewees were asked questions about uses, ways of handling, and perception of morphological variation in the carnaúba leaves. The number of leaves extracted and the income obtained from the sale of leaves were estimated from interviews and notes that each leader of extractors held during the year of the research and previous years, as well as direct observations made by researchers in the communities which recollection area of straw hold about 80 thousand individuals of C. prunifera. 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. 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 to be used for fertilization and construction. The relationship between the socioeconomic variables, income from extraction, and the number 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 years of residence in the community (R2 = 0.03 and p > 0.05); the number of leaves extracted and interviewee age (R2= 0.05 and p > 0.05); and the number of leaves extracted and extraction time (R2 = 0.04 and p > 0.05) did not indicate a relationship. Conclusion Local extractors observed that new leaves have the highest sales value, as they have the highest production of powder. In addition, economic factor is the preponderant force that directs the management strategies of native species. For this species, however, morphological and genetic studies are needed for further clarification.
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.
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. C. prunifera belongs to the Arecaceae family and its production chain includes a set of economic activities based on the use of the stipe, petiole, fiber, fruits, roots and leaves from which carnauba wax is extracted, an economically valuable resource in the region. Our hypothesis was that people would perceive morphological diversity in carnaúba. In addition, we expected to find a correlation between socioeconomic variables and the number of leaves used. 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 interviewees. Interviewees were asked questions about uses, ways of handling, and perception of morphological variation in the carnauba leaves. The number of leaves extracted and the income obtained from the sale of leaves was estimated from interviews and notes that each leader of extractors held during the year of the research and previous years, as well as direct observations made by researchers in the communities. 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 from extraction, and the number of leaves extracted (in thousands) was significant (R2 =0.73 and p<0.001).

It is possible that the economic factor is the preponderant force that directs the management strategies of native species. Thus, human selection and traditional plant management may be the main mechanisms that lead wild plant populations to the incipient domestication process. For this species, however, morphological and genetic studies are needed for further clarification.
