Influence of Land-Use Type on Forest Bird Community Composition in Mount Kenya Forest

الملخص EN

Few studies have explored how human land uses influence and support persistence of forest biodiversity in central Kenya.

In the case of the Mount Kenya ecosystem, farmlands and plantation forests are significant land-use types.

Using point counts, we assessed bird communities in natural forests, plantation forests, and farmlands in the Nanyuki Forest Block, Western Mount Kenya.

Bird point counts were undertaken during two sampling periods (wet and dry season).

Compared to farmlands and plantation forest, natural forest had the highest overall avian species richness and relative species richness of all except one forest-dependent foraging guild (granivores) and nonforest species, which occurred frequently only on farmlands.

Plantation forest had the lowest relative richness of all avian habitat and foraging guilds.

Conversely, specialist forest-dependent species mainly occurred in the structurally complex remnant natural forest.

Our study underscores the importance of remnant natural forests for the persistence and conservation of forest biodiversity and risks posed by replacing them with plantation forests and farmlands.
