Overgrazing refers to the excessive consumption of vegetation by livestock, resulting in the degradation of range land. This can lead to a decrease in plant diversity, soil erosion, loss of soil fertility, and ultimately desertification.
Characteristics of overgrazed range land include:
1. Reduced plant cover: Overgrazing can lead to the removal of vegetation, leaving the soil exposed to erosion.
2. Soil compaction: Continuous grazing can compact the soil, reducing its ability to absorb water and nutrients.
3. Loss of plant diversity: Overgrazing can favor the growth of certain plant species while suppressing others, leading to a decrease in overall plant diversity.
4. Decreased soil fertility: Overgrazing can deplete the soil of nutrients, making it less productive for plant growth.
5. Increased erosion: Without vegetation to hold the soil in place, overgrazed range land is more susceptible to erosion from wind and water.
6. Loss of wildlife habitat: Overgrazing can reduce habitat quality for wildlife species that depend on healthy range land for food and shelter.

Meaning of Overgrazing
Overgrazing occurs when livestock consume forage at a rate that exceeds the natural growth rate of vegetation, resulting in a decline in the health and productivity of the range.
Characteristics of Overgrazed Rangelands
- Reduced plant cover: Overgrazing removes vegetation, leaving bare soil exposed to erosion.
- Altered species composition: Desirable forage species are selectively eaten, leading to a dominance of less palatable or invasive plants.
- Reduced soil fertility: Plant roots help retain nutrients in the soil. Overgrazing removes these roots, reducing soil fertility and nutrient availability.
- Increased erosion: Bare soil is more susceptible to erosion by wind and water, leading to soil loss and degradation.
- Reduced water infiltration: Dense vegetation helps water infiltrate the soil. Overgrazing reduces vegetation, decreasing water absorption and increasing runoff.
- Diminished wildlife habitat: Rangelands provide habitats for various wildlife species. Overgrazing can reduce forage and cover, impacting wildlife populations.
- Economic losses: Overgrazing can lead to reduced livestock production, degraded soil, and decreased land value.
- Environmental consequences: Overgrazing can contribute to climate change by releasing carbon stored in vegetation and altering the water cycle.
