Mediterranean forests face an escalating wildfire crisis, but researchers in Spain have discovered an unlikely ally grazing in their midst. A groundbreaking study reveals that horses possess remarkable dietary flexibility that could transform how we approach forest fire prevention across the region’s vulnerable landscapes. Starting with highly flammable grasses like Mediterranean false brome, they gradually transitioned to consuming woody plants as grass supplies dwindled. Mediterranean regions experience increasingly severe wildfires driven by climate change, rural depopulation, and fuel accumulation from abandoned agricultural lands. Nevertheless, the dietary flexibility documented in this study suggests horses deserve serious consideration in Mediterranean fire management.
