Because of the growing and intense impact of human population on natural resources, environmental monitoring programs become increasingly necessary to continually evaluate such impacts and propose mitigation measures in a timely manner. However, effective monitoring programs are limited by the lack of time, fi nancial resources and qualifi ed professionals. Thus, this study aims to evaluate the most effective strategies to monitor the zooplankton community in the Lagoa Bonita, located in the Águas Emendadas Ecological Station, Planaltina (DF). The following issues were raised: (i) which is the zooplankton diversity at the study area? (ii) do the zooplankton groups show concordant patterns of spatial distribution? (iii) is there a signifi cant loss of information when using higher taxonomic levels (genera data instead of species data) and different numerical resolutions (species occurrence data instead of organisms density data?). The results of this study indicates that cladocerans, copepods and rotifers could be well evaluated in a environmental monitoring program at genus level, once the loss of species data information is low. On the other hand, all zooplankton groups and the information generated from density data must be considered.
