Grassland degradation in Inner Mongolia reaches critical levels, urgent action needed.
Grasslands in Inner Mongolia are at risk of degradation due to overgrazing. Researchers studied different types of grasslands and found that when grazing rates exceed 70-89%, the risk of degradation increases. Vegetation composition alone is not a reliable indicator of degradation. Instead, a spatial threshold ratio is crucial for preventing grassland degradation. This study provides valuable insights for managing and restoring degraded grasslands in Inner Mongolia.
