Microclimatic characterization of tourist caves in Parque Nacional Cavernas do Peruaçu, Minas Gerais, Brazil
Abstract The cave environment has very peculiar atmospheric conditions that directly influence the existence and maintenance of biotic and abiotic, socioeconomic, and historical-cultural elements represented by or associated with caves. In caves where tourist activities occur, the human presence may affect the delicate balance of these conditions. This study was developed to characterize the cave microclimates of seven caves that are part of the tourist itinerary in the Parque Nacional Cavernas do Peruaçu, located in the north of the state of Minas Gerais, Southeast Brazil. Temperature and relative humidity data were collected through 41 automated meters that each accumulated more than 110,300 readings. This research stands out for being one of the only long-term studies (2017 to 2019) developed in the country. The information analysis enabled not only characterization of the cave microclimate, but also observation of the relationship of these attributes with the internal morphology and the position of the caves in relation to the karstic relief of the region. The methodology developed in this study could support the Programa de Monitoramento das Condições Ambientais das Cavernas (Cave Environmental Conditions Surveillance Programme) to be implemented by the administration of the National Park, and identification of more sensitive environments in the interior of the caves will enable reordering of the visitation of these attractions.
