Resultados finales de la monitorización del LIG del icnofósil del gusano gigante (p.N. De Cabañeros) para el establecimiento de geoindicadores en la gestión del patrimonio geológico

Zusammenfassung

The final results of the analysis and interpretation of the data recorded by an instrumental monitoring system installed during three years at a geosite in the Cabañeros National Park (Ciudad Real-Toledo provinces, Castilla-La Mancha region, Central Spain) for the establishment of geoindicators for geoheritage management are presented. The geosite monitored was the ichnoffosil of an Ordovician giant worm situated at Boquerón del Estena reach. There, two geoindicators were established: one about its geoconservation status (incidence of effective cryoclastic processes); and another one relative to its public use access (interruption access to the existing pathway and footbridge during Estena river flash floods). The first presented no incidence during the monitored period, as there were no ice-thaw cycles on the surface of the rock, even though they were recorded at the air temperature. The second showed higher flood induced access cut temporary values than the ones that initially were expected and very short reaction time lags (less than six hours, flash floods) between the peak precipitation at the headwater and the peak flow of the hydrograph. Thus, this last result is considered fundamental for the management of the National Park visitor evacuation in case of emergency.
