Testudinidae Abstract The survival of the tiny native population of the western Hermann’s tortoise Testudo hermanni hermanni at the Albera Nature Reserve is threatened by nest predation. The initial purpose of this work was to test the efficacy of a commercial chemical repellent aimed at carnivores in the control of this predation. A total of 128 artificial nests containing quail eggs were distributed among eight 625-m2 plots. There were four control plots and four plots protected by repellent devices in a natural nesting area of the Albera; each plot contained 16 nests. All the nests, including the protected ones, were depredated after only 4 days. Due to the major role of the wild boar Sus scrofa as predator in this experiment, we decided to assess, by means of a second experiment (n = 160 artificial nests, 20 nests/plot), the efficacy of a specific repellent for this mammal combined with the initial repellent. The only noticeable effect of the combination of repellents was to delay predation, although after 4 days almost all protected nests had been depredated. We found both repellents unsatisfactory for reducing nest predation, necessitating the search for other methods of predator control.
