“…The informants reported high use of most of the investigated species, which is in accordance with earlier findings from the study area (Kristensen & Balslev 2003;Lykke et al 2004;Smith et al 1996;Wezel & Lykke 2006). Differences in use were related to three characteristics: informant's village, project-contact, and view on importance of the forest as a food source.…”

“…On one hand, many informants were concerned about a decline in the use of traditional foods, whereas on the other, people approved of the arrival of new products, were optimistic about the future, and generally found the species easy to get when asked specifically about each species. Regarding changes in vegetation status, a decline in vegetation cover is reported elsewhere from the same area (Lykke et al 2004) and is also reflected in answers from the structured interviews: the species reported to be harder to obtain are predominantly local trees, while the species perceived as easier to obtain are the newly introduced ones. In light of the importance of wild foods, the decrease in forest cover will reduce the food source considerably, both in daily life and in periods of hunger.…”

Ethnobotanical interviews on the use of food plants were conducted with 90 informants from two villages in eastern Burkina Faso. A total of 25 plant species and one type of stock cube were included in a structured questionnaire regarding use, importance, reasons behind use, changes in use, and preferences, followed by a supplementary semi-structured questionnaire about reasons behind use, changes, and preferences. Most species were highly used and considered important. Adansonia digitata L., Bombax costatum Pellegr. & Vuillet, Parkia biglobosa (Jacq.) R.Br. ex G.Don, and Vitellaria paradoxa C.F.Gaertn. were particularly important and useful species. Tradition, taste, health, and the lack of other possibilities were main reasons for people using the plants. A decline in traditional food products and an emergence of new products were observed. Answers were strongly related to informants' home-village and project-contact. There seems to be an extensive interest in health aspects and, consequently, a potential for an increased use of healthy traditional products if people are better informed about their nutritive qualities.

“…Mais, très peu d'études se sont focalisées sur l'utilisation des ressources végétales et leur dynamique [4,12,13]. Or, une bonne évaluation des facteurs influençant la dynamique de ces espèces, de concert avec les populations locales, pourrait contribuer à intégrer les savoirs locaux dans les stratégies de gestion de la biodiversité végétale.…”

--Introduction. Protected areas represent a huge reservoir of biological resources which local residents are highly dependent on. The non-inclusion of local knowledge is often an obstacle to conservation policy and sustainable use of biodiversity in these areas. The Reserve of Pama, located in the South-sudanian zone of Burkina Faso, is a good example of the discrepancy between the subsistence needs of local populations and the need to conserve biodiversity. Assessing the socio-economic importance of this reserve for local residents could lead to adapting a better strategy of natural resource management. Materials and methods. Ethnobotanical surveys were conducted based on interviews. The information obtained from the interrogation of 30 resource people identified the different uses made of the reserve by local people and the impact of these uses on the flora, and assessed the perception of villagers on the way of managing their forest resources. Results. A total of 58 plant species in the reserve, over 15% of the local flora, provide various resources to local populations, including construction equipment (90% response), medicinal plants (73.33%), food plants (73.33%), etc. The plant species most in demand were found to be, among others, Vitellaria paradoxa (80%), Parkia biglobosa (66.67%), Diospyros mespiliformis (33.33%), Gardenia erubescens (33.33%), Lannea microcarpa (33.33%), Tamarindus indica (33.33%), Andropogon gayanus (26.67%) and A. chinensis (26.67%). Some of these species have proved increasingly rare due to the deterioration of climatic conditions, abuse of green wood and soil depletion. Conclusion. The study we conducted on the reserve of Pama leads us to advocate stronger measures to protect the environment through the involvement of local residents. Moreover, the field planting of useful species in the process of depletion would be able to limit the operating pressure on the reserve.Burkina Faso / plant communities / biodiversity / plant genetic resources / resource conservation / environmental impact / Sudano-Sahelian region Dégradation des aires protégées par l'exploitation des ressources végétales : cas de la réserve partielle de faune de Pama, Burkina Faso (Afrique de l'Ouest).Résumé --Introduction. Les aires protégées représentent un immense réservoir de ressources biologiques dont dépendent fortement les populations riveraines. La non-prise en compte des savoirs locaux constitue souvent un frein aux politiques de conservation et d'utilisation durable de la biodiversité dans ces aires. La réserve de Pama, située en zone soudanienne au sud-est du Burkina Faso, est un bon exemple de la divergence existant entre les besoins d'autosubsistance des populations riveraines et la nécessité de conserver la biodiversité. L'évaluation de l'importance socio-économique de cette réserve pour les populations riveraines pourrait permettre de mieux adapter la stratégie de gestion des ressources naturelles.

The main objectives of this research were to determine which medicinal plants are culturally most important for the native community of Vencedor as well as testing a new measure of the cultural importance of medicinal plants that can be used outside of this one particular case. Data were collected through participant observation, informal conversation, and semi-structured and structured interviews to 31 heads of family. According to the Cultural Significance for Conservation Index (CSCI) developed, significant species were Petiveria alliacea L., Jatropha gossypifolia L., Mansoa alliacea (Lam.) A.H.Gentry, Hura crepitans L., and Banisteriopsis caapi (Spruce ex Griseb.) C.V.Morton. Our index showed a significant correlation with the other indices considered in this paper. We conclude that CSCI is a good indicator of the cultural importance of medicinal plants and that it can be useful in cases where there is a need to recognize which culturally important plants are more vulnerable.
