Biodiversity is important for the quality of agroecosystems. This study aims to analyze some components of biodiversity in agroecological systems lead by family farmers in the municipality of Choró, CE. Agricultural areas were selected by the time of adoption of intercropping systems as well as areas under natural vegetation used as reference. The soil fauna, the flora of the herbaceous and tree-shrub extracts, soil samples and coprolites were collected randomly or in transects to be analysed. The richness, and diversity and uniformity index (Shannon and Pielou, respectively) were also calculated. The adopted intercropping systems favour the soil fauna and flora diversity when compared to the natural vegetation areas.
