RESUMO

With the aim of understanding the impacts of visits by the public on inland aquatic ecosystems, the present study was developed at the Formoso river, Bodoquena plateau, Mato Grosso do Sul, Brazil. Through a case study, it was attempted to characterize the impacts provoked by different modes of public use of the Formoso river, considering the use of physical and chemical variables as indicators of public visitation impacts during the high season, Carnaval of 2006. In conjunction, to better understand the relationships between the impacts on the environment and the predominant use of the region, aspects of the relationship between tourist undertakings and the aquatic ecosystems of the Bodoquena plateau, the structure of the tourist undertakings open to the public along the river, and the profile and aspects of environmental perception of the visitors to these tourist undertakings were characterized. The data were obtained from research of documents, use of questionnaires filled-out by visitors to the river, and collection in the field of physical and biological variables describing different compartments of the aquatic ecosystem. The following results were obtained: 1. The aquatic environments are the most sought-after by the tourist undertakings and visitors; 2. the bathing areas exhibit the highest levels of impact of all the compartments analyzed of the aquatic ecosystem; 3. water movement and trampling of the bottom substrate are the most pronounced interferences of public visitation in the river; 4. the most impacted areas receive the least environmentally demanding visitors; 5. the variables water transparency, leaf litter, richness and diversity of benthic macroinvertebrates, and the index of ecosystem physical structure alteration were selected as the most applicable indicators of environmental evaluation and monitoring of public visitation impacts on the Formoso river.
