This poster presents work carried out as part of a PhD thesis comparing geosites management methods in 2 UGG working together: M’Goun (Morocco) and Massif des Bauges (France) Geoparks.The ongoing inventory of geosites is one of the conditions for success and for maintaining UGG status. How to integrate ongoing addition of geosites to the management of the geosites collection grounding a Geopark is the stake of the study, analysing first the strategy used by the Massif des Bauges UGG to manage the increase from 50 initial geosites to 73 current ones.
