The public school students in Cariri Paraibano are mostly children of farmers and use the native vegetation along with their families for various purposes, leaving the Caatinga vulnerable to several negative environmental impacts. The objective of this study was to detect the use value and the local knowledge of the students in relation to arboreal-shrub species, considering their usefulness and the vulnerability, threats and extinction dangers arising from this process. The work was carried out in 2016, with an argumentative questionnaire, composed of 8 open questions, with 480 students from 30 classes of 1st, 2nd and 3rd year of each school in the municipalities of Asunción, Gurjão, Livramento, Monteiro, Parari, Serra Branca, São João do Cariri, São José dos Cordeiros, Santo André and Sumé. It was decided to work with one public school per city and the choice of these urban centers occurred in a random way. The purpose of the applied questionnaire was to evaluate the students' knowledge regarding the use, conservation and vulnerability of the Caatinga vegetation. They were mentioned by 59 species, belonging to 25 families. The families of the students use 41 species, highlighting food, medicines and fodder. The species with the highest values of use were Spondia tuberosa, Anacardium occidentale and Miracrodruon urundueva. The students cited 36 species of little concern, threatened and in danger of extinction. The results also show that schoolchildren need to be more aware of the state of vulnerability, so that they can use native species in a sustainable manner based on conservation principles, anchored in Environmental Education and the appreciation of local conservation knowledge.
