Desert ecosystems support remarkable wildlife adapted to extreme conditions. Climate change is intensifying aridification, pushing even desert-adapted species beyond their physiological limits.
Desert wildlife welfare is shaped by the fine line between physiological tolerance and lethal heat or dehydration. Animals adapted to survive 40C temperatures may be pushed beyond tolerance by 45C events that are becoming more frequent. Small mammals in desert burrows, unable to thermoregulate externally, may experience fatal heat stress even when sheltering. Desert reptiles that need specific thermal environments for reproduction may fail to find suitable conditions. The welfare harms of aridification are largely invisible - animals dying alone of heat stress or starvation in remote landscapes - but the suffering is real and increasing. Conservation interventions focus on maintaining water sources and protecting remaining natural vegetation.
