We investigated the influence of socioeconomic factors (age, gender, and occupation) on the local knowledge of medicinal plants in the Araripe National Forest, Brazil, and the priority of conservation of the species as perceived by people. Additionally, priority species for in situ conservation were identified by calculating conservation priority (CP). Initially, free lists were developed with 152 informants in order to identify the plants known and used by them. Based on the most cited plants in these lists, a salience analysis was performed to identify the ten most prominent tree species. In a second moment, through a participatory workshop, these ten species were classified by the perception of local experts as to their environmental availability and intensity of exploitation. Then, the population size of the forest plant species was quantified through a phytosociological sampling and the conservation priority index (CP) of the species was calculated. A total of 214 ethnospecies were cited by the informants, which were identified in 167 species. Local knowledge was influenced by socioeconomic factors, with positive correlation between age and local knowledge and difference in knowledge among professions. Among the ten most prominent tree species in terms of their medicinal importance, was highlighted as a priority for conservation in the experts' perception because it has low environmental availability and a high exploitation rate. The ten species were ordered by the CP differently from the ordering made by the local experts' perception, indicating that people's perception of species conservation status may not correspond to the actual situation in which they are found in the forests. Conservationist measures based on the perception of informants need complementary ecological studies on the species accessed.
我们调查了社会经济因素（年龄、性别和职业）对巴西阿拉里皮国家森林中药用植物当地知识的影响，以及人们所感知的物种保护优先级。此外，通过计算保护优先级（CP）确定了原地保护的优先物种。最初，与152名信息提供者编制了自由列举表，以确定他们已知和使用的植物。基于这些列表中被提及最多的植物，进行了显著性分析以确定十种最突出的树种。在第二个阶段，通过一个参与性研讨会，当地专家根据对这十个物种的环境可获得性和开发强度的认知对其进行了分类。然后，通过植物社会学抽样对森林植物物种的种群规模进行了量化，并计算了物种的保护优先级指数（CP）。信息提供者共列举了214个民族植物种类，经鉴定为167个物种。当地知识受到社会经济因素的影响，年龄与当地知识呈正相关，不同职业之间的知识存在差异。在药用重要性方面的十种最突出树种中，专家认为[物种名称未给出]是保护的优先物种，因为它的环境可获得性低且开发率高。这十个物种按CP排序与当地专家认知的排序不同，表明人们对物种保护状况的认知可能与它们在森林中的实际情况不符。基于信息提供者认知的保护措施需要对所涉物种进行补充性生态研究。
