Lund Warming is in central-southern Minas Gerais at the intersection between two biodiversity hotspots, the Cerrado (Brazilian savannah) and the Mata Atlântica (Atlantic Forest). It presents multiple surface water catchments that seasonally flood, forming a system of temporary lakes which confer to the Site its high biodiversity value and scenic beauty. Hundreds of caves, shelters and important archaeological and palaeontological sites are found, containing a large number of fossils, artefacts and drawings of the first human settlements. The Site also hosts threatened species such as the vulnerable masked titi (Callicebus personatus). Mining activities in the surrounding area have caused the loss of native vegetation and changes in the quality of the surface water and groundwater.
