Many human activities affect arthropod diversity and may threaten environmental health. Some insects may act as biological indicators based on their presence or absence in an ecosystem. The present study was conducted from 2006 to 2009 to evaluate changes in the diversity and abundance of ground Carabids following restoration activities conducted in three lowlands ecosystems that had previously experienced high levels of human pressure in Burkina Faso. Three micro-catchments were identified in the regions of Soum, Sanmatenga, and Kompienga, using a hydrographic chart of Burkina Faso. The diversity and abundance of carabids collected in pitfall traps at the beginning and end of the rainy season were compared using 2006 as a sampling reference year with restoration activities (abandonment of farming, forestation and scarification) occurring in 2007. Post-treatment surveys were conducted in the same seasons of 2008 and 2009. Forty-nine species of Carabids have been identified based on monitoring of 1800 pitfall traps. The number of species generally increased in 2008 and 2009, from 9 to 41 species in the three micro-catchments. Species richness and insect abundance definitely increased where human pressure decreased and restoration measures were successfully conducted. However, Carabid diversity increased only in Soum micro-catchment; this site seemed to be more affected by restoration. Carabids are likely to be good indicator species; reports can be prepared relatively quickly. The results are discussed in relation to the goal of developing ecologically sound tools based on bio-indicator insects that can be used for environmental management.

Abstract
Many human activities affect arthropod diversity and may threaten environmental health. Some insects may act as biological indicators based on their presence or absence in an ecosystem. The present study was conducted from 2006 to 2009 to evaluate changes in the diversity and abundance of ground Carabids following restoration activities conducted in three lowlands ecosystems that had previously experienced high levels of human pressure in Burkina Faso. Three micro-catchments were identified in the regions of Soum, Sanmatenga, and Kompienga, using a hydrographic chart of Burkina Faso. The diversity and abundance of carabids collected in pitfall traps at the beginning and end of the rainy season were compared using 2006 as a sampling reference year with restoration activities (abandonment of farming, forestation and scarification) occurring in 2007. Post-treatment surveys were conducted in the same seasons of 2008 and 2009. Forty-nine species of Carabids have been identified based on monitoring of 1800 pitfall traps. The number of species generally increased in 2008 and 2009, from 9 to 41 species in the three micro-catchments. Species richness and insect abundance definitely increased where human pressure decreased and restoration measures were successfully conducted.

De nombreuses activités humaines affectent la diversité des arthropodes et peuvent menacer la santé de l'environnement. Certains insectes peuvent agir comme indicateurs biologiques en fonction de leur présence ou absence dans un écosystème. La présente étude a été menée de 2006 à 2009 pour évaluer les changements dans la diversité et l'abondance des carabes suite à des activités de restauration menées dans trois écosystèmes des plaines qui avaient connu des niveaux élevés de pression humaine au Burkina Faso. Trois micro-bassins ont été identifiés dans les régions du Soum, Sanmatenga et Kompienga, en utilisant une carte hydrographique du Burkina Faso. La diversité et l'abondance des carabes recueillis dans des pièges à fosse au début et à la fin de la saison des pluies ont été comparées en utilisant 2006 comme année de référence d'échantillonnage avec des activités de restauration (abandon de l'agriculture, reboisement et scarification) effectuées en 2007. Des enquêtes post-traitement ont été menées dans les mêmes saisons en 2008 et 2009. Quarante-neuf espèces de carabes ont été identifiées sur la base de la surveillance de 1800 pièges à fosse. Le nombre d'espèces a généralement augmenté en 2008 et 2009, de 9 à 41 espèces dans les trois micro-bassins versants. La richesse en espèces et l’abondance des insectes a certainement augmenté où la pression humaine a diminué et les mesures de restauration ont été menées avec succès. Cependant, la diversité des carabes a augmenté seulement dans le micro-bassin versant du Soum; ce site semblait être plus touché par la restauration.
