This resulted in the emergence of the terms natural capital and ecosystem services, which are defined as the benefits people obtain from ecosystems. The traditional approach to ecosystem services overlooks the services provided by geodiversity, which comprises the diversity of non-living nature. This article aims to quantitatively assess and map the ecosystem services provided by geodiversity in the Carajás National Forest, located in Pará, Brazil, referencing its management plan. The study area also includes the Campos Ferruginosos National Park. The methodology was in two main stages: (i) Identification and classification of ecosystem services provided by geodiversity; (ii) Counting occurrences of each type of geodiversity service. Variables were grouped into regulation, support, provisioning, and cultural categories. Considering the relevance of cave occurrences, speleosystemic services were included. Ecosystem services in the Carajás National Forest mining zone are very high in all categories, mainly from the presence of over 900 caves. This area includes iron, manganese, deactivated gold, licensed but not yet installed copper, sand, and granite mines. The mining zone aims to minimize the impact on adjacent areas and prioritize recovering degraded areas with native species, prohibiting invasive exotics. The management plan does not directly address caves crucial for ecosystem regulation, water quality, and soil stability. Besides caves, high-altitude lakes play a fundamental role in regulating the hydrological cycle and promoting water quality. Provisioning services are very high in the mining zone but only medium in the Sustainable Forest Management zone, where timber management is unfeasible due to mining impacts. The Preservation Zone, classified as having low potential for geodiversity ecosystem services, maintains nature in its most primitive state. It is essential for regenerating other zones and preserving ecosystems and genetic resources.
