Les oiseaux cavicoles : indicateurs de l’état des systèmes agroforestiers à base de café dans les Ghats Occidentaux, Inde

Abstract : This paper aims to find an indicator of the state of coffee based agroforestry systems in the Western Ghats, India. Coffee plantations are modified at different degrees. Within the plantations, forest tree populations are altered and can be totally replaced by an exotic species Grevillea robusta. We studied the potential use of the cavity-nesting birds community as an indicator of the state of coffee based agroforestry systems. We sampled 14 species along the plantations using the playback method. Their presence was described using the characteristics of forest tree populations, landscape and management of the coffee. We found that the species richness of cavity-nesting birds was positively influenced by the tree species richness and the average DBH (Diameter at breast height). The species richness of cavity-nesting birds showed a strong decrease with a percentage higher than 20 % of Grevillea robusta. The members of this community responded differently to the forest tree population’s characteristics. The primary excavators were the most affected by the presence of Grevillea robusta. Cavity-nesting birds can describe the state of coffee based agroforestry systems regarding the forest-tree population’s characteristics but not the landscape background or the management of the coffee.
