Desert tortoises face multiple welfare threats from habitat loss, road mortality, and disease. Understanding their challenges informs effective conservation responses.
Desert tortoise welfare is threatened by slow-moving but devastating forces — habitat loss, disease, and road fragmentation of their populations. Road mortality affects all age classes but has particular population impact for large, reproductively active adults who have survived decades to reach maturity. Tortoise tunnels have been shown to reduce road mortality significantly. Disease transmission through poorly managed translocation programs has created welfare concerns even in conservation activities. Understanding that conservation interventions can inadvertently cause welfare harm requires careful planning and disease screening before any tortoise relocation.
