How did domestic cattle, sheep, and goats affect wild bovid habitats?

Domestic cattle, sheep, and goats have significantly impacted wild bovid habitats by dominating and degrading ecosystems such as savannas, steppes, and subdeserts. As human populations have expanded, these livestock have replaced natural habitats, leaving increasingly limited space for wild species.1

The presence of large livestock herds affects these environments in several ways:

• Habitat Degradation: Livestock often overgraze vegetation, which inhibits plant growth and reduces the availability of food for wild herbivores.2
• Soil Damage: Through trampling, livestock destroy plant roots that bind the soil, leading to erosion and soil compaction, which further hinders vegetation recovery.2
• Ecological Shifts: By selectively consuming certain edible plant species, livestock provide a competitive advantage to inedible plants, such as cacti or shrubs, which can permanently alter the composition of the plant community and prevent grasses from recolonizing.2
• Direct Competition: Because livestock are husbanded by humans, they have been able to thrive in ecosystems where they might otherwise struggle, effectively displacing wild bovids that are often better adapted to those specific environments.1

Ultimately, the widespread expansion of livestock has played a major role in the decline of many wild bovid populations.1
