The development of conservation strategies for nontimber forest products requires the characterization of the management systems and ethnoecological knowledge of the used species, as well as the analysis of the biological impacts of these processes. This study aimed to evaluate management systems and extractivist areas and related ethnoecological knowledge of Dimorphandra gardneriana (fava d’anta) in the semiarid region of Ceará, Northeast of Brazil. Fava d’anta produces fruits with high concentration of bioflavonoids, substances with various pharmacological properties, being exploited by extractivist communities in the mosaic of protected areas in Chapada do Araripe, Ceará. Ethnoecological knowledge has been concentrated on collectors who have been in activity for a longer time and/or plant the species. We identified three management systems that can impact in different ways on fava d’anta populations, depending on the area and level of human interference with the species. The extractivists respect the zoning of protected areas and do not enter in the full protection area, choosing areas with the highest tree density. The different systems produce a mosaic that creates different extraction opportunities and modifications to the local landscape and to fava d’anta populations. Factors that may have effects on the conservation of the species are the lack of supervision and overexploitation of the resource in native areas, while the factors that affect the health of extractivists are the infrastructure of the work and exposure to wild environments.

巴西东北部 Chapada do Araripe Semiarid Ceará 保护区内 Dimorphandra gardneriana 的民族植物学和管理

非木材林产品保护战略的制定需要对所用物种的管理系统和民族生态学知识进行描述,以及对这些过程的生物影响进行分析。本研究旨在评估巴西东北部塞阿拉州半干旱地区的 Dimorphandra gardneriana (fava d'anta) 的管理系统和采掘区以及相关的民族生态学知识。Fava d'anta 生产的水果含有高浓度的生物类黄酮,这些物质具有多种药理特性,被塞阿拉州 Chapada do Araripe 保护区马赛克中的采掘业社区所利用。民族生态学知识集中在从事活动时间较长和/或种植该物种的采集者身上。我们确定了三种管理系统,它们可以以不同方式影响蚕豆种群,具体取决于人类对该物种的干扰的区域和水平。采掘主义者尊重保护区的分区,不会进入完全保护区,选择树木密度最高的区域。不同的系统产生马赛克,为当地景观和蚕豆种群创造不同的提取机会和修改。可能对物种保护产生影响的因素是缺乏监管和对本地资源的过度开发,而影响采掘者健康的因素是工作的基础设施和对野生环境的暴露。取决于人类对该物种的干扰的面积和程度。采掘主义者尊重保护区的分区,不会进入完全保护区,选择树木密度最高的区域。不同的系统产生马赛克,为当地景观和蚕豆种群创造不同的提取机会和修改。可能对物种保护产生影响的因素是缺乏监管和对本地资源的过度开发,而影响采掘者健康的因素是工作的基础设施和对野生环境的暴露。取决于人类对该物种的干扰的面积和程度。采掘主义者尊重保护区的分区,不会进入完全保护区,选择树木密度最高的区域。不同的系统产生马赛克,为当地景观和蚕豆种群创造不同的提取机会和修改。可能对物种保护产生影响的因素是缺乏监管和对本地资源的过度开发,而影响采掘者健康的因素是工作的基础设施和对野生环境的暴露。不同的系统产生马赛克,为当地景观和蚕豆种群创造不同的提取机会和修改。可能对物种保护产生影响的因素是缺乏监管和对本地资源的过度开发,而影响采掘者健康的因素是工作的基础设施和对野生环境的暴露。不同的系统产生马赛克,为当地景观和蚕豆种群创造不同的提取机会和修改。可能对物种保护产生影响的因素是缺乏监管和对本地资源的过度开发,而影响采掘者健康的因素是工作的基础设施和对野生环境的暴露。
