“…Outros trabalhos atestam a importância desta espécie em outras regiões, onde a coleta é mais expressiva do que a observada no local (Souza et al 2006). Outras espécies citadas como ornamentais, Epidendrum fulgens e Ipomoea pes-caprae, chamam a atenção por suas fl ores coloridas e vistosas e são preservadas nos terrenos ou coletadas e replantadas nos quintais.…”

(Ethnobotany and urbanization: knowledge and use of restinga plants by the native community of Distrito do Campeche (Florianópolis, Santa Catarina, Brazil)). Th e occupation of the Brazilian coastline has increased greatly over the past decades, leading to urbanization of areas previously occupied by traditional populations. Th is study aimed to investigate the ethnobotanical knowledge of restinga species of members of the local community of Azorean descendents living in the Campeche District (Florianopolis, Santa Catarina, Brazil), an area suff ering from an accelerated process of urbanization. We selected informants through purposive sampling and we did 15 interviews with native residents from 42 to 84 years old. Th e native residents that experienced the past rural reality in the area have ethnobotanical knowledge of restinga plants related to times gone by, when many species were used for their maintenance and survival, but they are also increasing this knowledge with plants currently in use, mainly in the medicinal category. From the rural past to the urban present, use frequency of cited plants decreased considerably, which may cause a loss of ethnobotanical knowledge among future generations. Ethnobotanical research in changing areas contributes to the valorization of local cultures and can attach cultural value to restinga vegetation, thus contributing to the conservation of this ecosystem.

“…Another possible negative impact is the ecological effects on the resource [ 73 ], since the intensity of leaf extraction (especially immature) can reduce the size and biomass of reproductive and vegetative structures, according to Vieira et al [ 71 ]. One of the implications of this is the importance of seeking strategies for the sustainable use of biodiversity resources of economic importance, such as the carnaúba leaf, in order to match the conservation of natural resources with income for human populations that use such resources [ 74 , 75 ].…”

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. 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). 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 number of leaves extracted and extraction time (R2 =0.04 and p>0.05) did not indicate a relationship.Conclusion: C. prunifera is economically and culturally important for the studied communities. 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.
