HABITAT USE BY THE EUROPEAN WILD RABBIT (ORYCTOLAGUS CUNICULUS) IN A COASTAL SANDY DUNE ECOSYSTEM OF CENTRAL ITALY

The European wild rabbit (Oryctolagus cuniculus) has been recurrently introduced into Italy since the Roman times. Some populations occur along sandy coastal dunes (Central Italy). There is no information about the ecology and habitat preferences of wild rabbits in this particular ecosystem. During May and June 2009, we assessed the distribution of wild rabbits in a 120 ha protected area (province of Livorno, Tuscany), by faecal pellet counts in 170 circular plots (d = 1 m). Range size defined by Kernel Analysis was 27.3 ha (95%) and 13.2 ha (50%). Habitat selection was assessed through Jacobs' index of selection. Rabbits selected the first dunes that offer both food (psammophilous grasses) and the cover of tamarisk shrubs. Holm oak woods and pinewoods were avoided, probably because of the lack of undergrowth.
