In Corsica

In Corsica, the decline of the populations appears to be less severe yet very real (particularly south of Bastia, in the Porto-Vecchio area and in the Gulf of Ajaccio). Its decline is mainly due to fire forests and urbanisation; these two threats have grown in the last twenty years.
However, given the healthy numbers observed and the population dynamics, the situation is of far lesser concern here than it is on the mainland.
