- Abstract
Agroforestry systems in transformed landscapes could be used as a tool to increase connectivity and heterogeneity in rural landscapes. Biodiversity functional groups have received great attention for several years as they influence supply of ecosystem services through sustaining of different ecological processes. We assessed the bird diversity, functional groups and ecosystem services they provide on a Colombian coffee landscape. We estimated richness, diversity and functional groups in three types of vegetation: forest fragments and two agroforestry systems: shaded coffee plantations and wooded pastures. Bird richness was similar between agroforestry systems and forest fragments, forests are the richest (S =71), followed by shaded coffee plantations (S =69) and finally the wooded pasture (S =63). Among vegetation types, despite differences found in the floristic and structural composition, the trees are common elements in all the vegetation types. There was no correlation between structural elements and composition of vegetation with the richness and diversity of birds responded to an altitudinal variation of the sampling sites. Furthermore, taking into account the functional characteristics of food and body weight guild, 18 functional groups are formed, of which 17 were found in wooded pastures and 16 coffee plantation and forest. The small birds that feed on small invertebrates and fruit were the most redundant group. In conclusion, in previously forested landscapes, when tree elements and floristic complexity increases, birds diversity and richness is greater. We recommend further research in each functional group to understand the economic value of services they provide, in order to seek arguments to promote birds conservation in transformed landscapes.
