Abstract : This is an ethnobotanical study focused on the traditional medicinal plants used by local communities to treat human diseases. It was carried out from March to September 2020, in Righa dahra forest in the wilaya of Setif, Algeria. This forest is located in a bioclimatic transition zone with vegetation stages from the thermo Mediterranean to the supra Mediterranean, which contribute to develop a very important floristic richness. The research was based on a data that collected using semistructured interviews, group discussions and questions asked to the population of this region; experienced elderly people, men and women ... about herbal remedies and how to use them in traditional medicine. Descriptive statistical analysis of 100 interviews were identified a total of 58 medicinal plants, distributed in 30 families plant. The result showed that grass constituted the highest proportion of medicinal plants (55%) followed by shrubs from which it was found that Artemisia herba-alba and Juniperus phoenicea are the most useful species by the population of this region. Plants families with the highest medicinal plants in the study area used for various diseases treatment were Lamiaceae, Apiaceae and Cupressaceae. Leaves (27%) were the most frequently utilized plant parts for preparation of traditional herbal medicines. Oil was a widely used mode of preparation of traditional remedies followed by infusion. It appears that most plants are used in the treatment of 30 condition bellings to seven diseases groups of which gastrointestinal diseases and respiratory diseases are the most treated by plants.

Abstract : This work consists in evaluating the viability and the degradation by the various pressures affecting the stand of Q. suber and Q. canariensis of the Ouled Bechih forest. The collection of data related to this work has used a random forest inventory and a count of pressures. The state was evaluated by analyzing these components. The results obtained showed that the stand of the Ouled Bechih forest is of good quality according to the PHF index (221) and zero mortality, but this does not prevent the forest from being subject to pressures of biotic and abiotic origin. Grazing and illegal logging are the most important pressures from anthropic actions. However, these pressures, the forest are classified as a viable ecosystem. This good level of viability of this forest implies the proposition of a management plan to conserve it; monitoring is an essential activity, hence the propositions of a permanent monitoring plan for the forest.
