Inventory and assessment of geological sites at Alto Ribeira Touristic State Park (São Paulo, Brazil): A contribution to its management

Abstract

Over the past decade, various methodologies have been developed to systematize, discuss, and propose measures for protecting and sustainably managing geological heritage. The Alto Ribeira Touristic State Park is a crucial component of the most significant network of protected areas in the State of São Paulo, Brazil. It has international recognition for its speleological heritage, which underpins its status as a popular tourist destination. This intensive touristic use necessitates solid management plans that ensure sustainable tourism while preserving the karst features. Therefore, this work refined the inventory of geological sites and provided a quantitative assessment of their degradation risk and potential for use. Three geosites and twenty four geodiversity sites were identified and assessed. The quantitative evaluation of these geological sites was conducted using the System for Registration and Quantification of Geosites and Geodiversity Sites (GEOSSIT), which was developed by the Geological Survey of Brazil. The application of this tool, designed for use in a vast and diverse country like Brazil, revealed the need for adaptations when applied to a smaller area such as Alto Ribeira Touristic State Park. This work helped establish management priorities for these sites and determine the most suitable uses for each geological site, providing valuable information for park managers. Such studies demonstrate that proper management of protected and conserved areas should always include geodiversity and geoconservation in their action plans.
