Abstract

Conversion of forest to agricultural plots, plantations, and pastureland is one of the top two reasons for the unprecedented rate of tropical forest destruction. Coffee, in terms of area, is the most important crop in Costa Rica and continues to threaten remaining forest (Lean 1990). This study examined how proximity of coffee plantations to forest stands affects avian diversity, and the role of avian insectivores on coffee herbivory. Avian diversity was studied at two coffee plantations, one near and one far from the forest. Avian diversity was significantly higher in the near-forest coffee plantation than in the far forest. However, there was no significant difference in herbivory or insectivory between the two sites. These results suggest that forest stands are important to the conservation of avian diversity in coffee plantations.

Resumen

La transformación del bosque en parcelas de agricultura, plantaciones y fincas ganaderas es uno de las razones más importantes de la destrucción del bosque tropical. El café es el cultivo mas importante en Costa Rica y por lo que amenaza la sobrevivencia del bosque existente (Lean 1990). Este estudio examino como el efecto de la proximidad de los cafetales al bosque influye sobre la diversidad de las aves, depredación de larvas y el porcentaje de herbivoría del café.
