The main objective of this article was the assessment of the impact of damage caused to the MIOMBO clear forest on the diversity of litter fauna. In order to lead to results it was specially selected three different stations (the MIOMBO clear forest, the shrub savannah and the farmed field) those were characterized by the pH, the water content and the organic matter concentration of their soil. The litter fauna species listed on the inventory of the Miombo forest were compared in quality and quantity to those listed in shrub savannah and the land under farming after the calculation of diversity indications. So it was brought out that the acidity and the organic matter concentration were more considerable in the soil of the forest than the shrub savannah and the land under farming. The same goes for the litter fauna that was more abundant and diversified in the forest (to wit the relative abundance of 59, 8%) than the land under farming that has registered 30, 4% of all listed species and the shrub savannah with 9, 8% only. These results constitute the evidence that damages caused to the MIOMBO clear forest has negative actions on the abundance and diversity of the litter fauna.

Abstract: (french)
Cet article a eu comme objectif principal d’évaluer l’influence de la dégradation de la forêt claire Miombo sur la diversité de la faune de litière. Pour aboutir aux résultats il a été sélectionné trois stations différentes (la forêt claire Miombo, la savane arbustive et un champ cultivé) qui ont été caractérisées par le pH, la teneur en eau et la concentration en matière organique de leurs sols. Les espèces de la faune de litière inventoriées dans la forêt Miombo ont été comparées quantitativement et qualitativement à celles de la savane arbustive et du sol sous culture après calcul des indices de diversité. Ainsi il s’était dégagé que les sols de forêt ont une acidité importante et une forte teneur en matière organique que ceux de la savane et du champ cultivé. Il en va de même pour la faune de litière qui a été significativement abondante et plus diversifiée dans la forêt Miombo (soit une abondance relative de 59,8%) que dans le sol sous culture qui a enregistré 30,4% des espèces inventoriées et la savane avec 9,8% seulement. Ces résultats constituent une preuve que la dégradation de la forêt Miombo agirait négativement sur l’abondance et la diversité de la faune du sol.
