Resum
The evolution of the conservation status of several geosites has been estimated: Covadonga Lakes and Comeya Hollow (Picos de Europa National Park); Cirque of Marboré (Ordesa y Monte Perdido National Park) and Pleistocene glacial lakes of Somiedo (Somiedo Natural Park). They all have similar characteristics that have allowed us to establish a common analysis methodology: a) they are all glacial lakes, whose main geological interest is of geomorphological type; b) they have been subjected to a direct human environmental impact; c) they are currently included in protected natural areas of Spain (national parks and a natural park). To quantify the development and monitoring of the condition of the geoheritage, a system of indicators has been designed to monitor the changes experienced at present and, above all, to estimate of conservation status in the past from historical data and the multi-proxy analysis of cores recovered from their sedimentary filling. Multidisciplinary evaluation and monitoring of these physical-chemical and paleolimnological indicators will provide scientific criteria for the estimation of their ancient and present conditions and to adopt dispositions for their future conservation.
