Two major studies are shedding new light on the impact of Mexican gray wolves on cattle ranchers in Arizona and New Mexico. Researchers from the University of Arizona and UC Davis analyzed financial losses, stress levels in cattle, and wolf diets, finding both direct and indirect effects on herds. While ranchers report significant losses tied to wolf predation and stress, environmental groups argue the studies may overstate the problem and call for a more balanced view. The debate over wolves, livestock, and conservation continues.
