Responses of reptile populations to the eradication of the Roof Rat (Rattus rattus) on Bagaud Island (Port-Cros National Park, Var, France)
National audience An eradication of two invasive taxa, the Roof Rat (Rattus rattus) and Ice plants (Carpobrotus spp.), was undertaken in 2011 and 2012 on the protected nature reserve of Bagaud island, located in Port-Cros national Park (south-eastern France). R. rattus eradication was successful whi...
