Chelonian trouble: threats and future challenge for its conservation Among the 324 species of chelonians currently known, approximately one-quarter are currently threatened with extinction. The factors leading to the disappearance of these species have been directly linked to human activity. Major threats include the increasing commercial trade that drives the overexploitation of many species, the lucrative market for products derived from turtles (traditional Chinese medicine and decorative objects), both legal and illegal pet markets, and habitat loss. In this context, some species are now very scarce, having only a few dozen individuals in surviving populations, while there is even a species with only one living individual still in existence. In the case of the Hermann’s tortoise, while some of its populations (e.g., in l’Albera, Alt Empordà) or in certain regions (Romania) survive at critically low levels, its overall situation is not as severe and therefore it is currently classed as “almost threatened” by the IUCN. The general causes of its disappearance are somewhat similar to those affecting most of the chelonian species. Nevertheless, Hermann’s tortoise is not currently eaten and its main threats stem from the loss of habitat, poaching, and significant increases in the populations of its predators. If the most threatened populations are to recover, it is necessary to implement efficient management of their habitat and to eliminate poaching, which affects both natural and reintroduced populations. In terms of the latter, we need to teach people to see the Hermann’s tortoise as a wild animal, so they will be able to understand that its place is the wild.
