  Timeframe: 2017 - 2020 // 2019 - 2022
  Country/Region: Sardinia, Italy
  Partner: Capo Carbonara Marine Protected Area
  Most of the latest bird species extinctions occurred on islands were caused by alien species introduction. Colonial seabirds are among the most vulnerable species, being adapted to breed only in areas where terrestrial predators are absent. Islands originally offered them the required safety conditions, until man introduced on most of them (intentionally or not) a number of alien species, the most widespread among them being the black rat. On Italian islands, two seabird species are particularly prone to rat predation and especially important in terms of viable nesting populations: the Scopoli's Shearwater and the Yelkouan Shearwater.
  This project aims at the complete eradication of the invasive black rat from two islands in the Capo Carbonara Marine Protected Area in the southern part of Sardinia, Serpentara and Cavoli. On both islands, the eradication will be done through the use of traditional bait dispensers selective for rat-sized animals. The seabird populations will be closely monitored to assess the impact of the activity, and a bio-security program integrated with a communication program targeted at boat-owners and tour operators will be put in place to reduce the risk of rats' return.
  In 2019, Fondation Segré granted a small addendum to the project to further expand the biosecurity program to mainland Sardinia, on the promontory of Capo Carbonara, in order to limit any risk of rats' recolonisation on the close islands of Serpentara and Cavoli.
