Scientists have found that feral horses can damage native environments in various ways:
- increasing soil erosion, by killing vegetation, disturbing the soil and creating paths along frequently used routes
- destroying native plants, by grazing and trampling
- fouling waterholes
- collapsing wildlife burrows
- competing with native animals for food and shelter
- spreading weeds, through their dung and hair.
