Overgrazing by livestock is a significant threat to the Sonoran Desert's delicate ecosystem.

Overgrazing is a common issue in the Sonoran Desert, particularly by livestock like cattle and sheep. When these animals graze too much, they can strip away vegetation that is vital to the ecosystem, leaving the land vulnerable to erosion and loss of biodiversity. Without the vegetation to anchor the soil, desertification can occur, where fertile land turns into barren desert. This disrupts habitats for native species, including plant and animal life that depend on specific vegetation for food and shelter. Managing livestock grazing is critical for maintaining the desert’s health and resilience.
