The vegetation of the Asinara National Park, established in 1997, is dramatically degraded as a consequence of the intensive human use during the last centuries. Fire, overgrazing, intensive and extensive farming activities, carried out during the 112 years of the presence of a penal colony, determined the spread of secondary plant communities. Human induced effects are evident also in the communities of the psammophilous and hygrophilous geo-sigmeta.
