Feral pigs, European rabbits, and wild boars are all invasive species that pose a significant threat to native plants in the Sonoran Desert.

Invasive species like feral pigs, European rabbits, and wild boars are causing harm to the delicate balance of the Sonoran Desert ecosystem. These animals often compete with native species for food and resources, while their feeding habits damage native plants. For example, wild boars root up the soil and destroy cacti, while European rabbits and feral pigs consume desert vegetation, preventing the regeneration of native plants. Their presence disrupts the desert's plant life, which in turn affects the wildlife dependent on those plants.
