The ecological impact of overgrazing on grasslands includes soil degradation, reduced biodiversity, and altered hydrology. Excessive grazing pressure by livestock can lead to the loss of native vegetation and the proliferation of invasive species, disrupting the natural balance of the ecosystem. Overgrazing compacts the soil, reducing its ability to retain water, which exacerbates erosion and can result in desertification over time. Additionally, it diminishes habitat quality for wildlife, impacting species dependent on healthy grassland ecosystems. Sustainable grazing practices are essential to prevent these detrimental effects and promote ecosystem health.
