In a part of Brazil, scientists used satellite pictures to see how much grass is growing in pastures and how much soil is being lost. They found that places with more plants lose less soil.
No biological mechanisms were identified in this study. This may be an epidemiological, observational, or survey-based study that reports associations rather than proposing causal biological pathways.

If you keep chickens on the same pasture all the time without rotating it, the soil gets worse, the grass doesn't grow as well, and there are fewer bugs and plants for the chickens to eat.
Most of the pastureland in this part of Brazil's savanna is somewhat damaged — not the worst, but not healthy either — and this 'medium damage' covers more area than any other type.
Most of the eroded land in a Brazilian savanna watershed is in damaged pasture areas, and the biggest chunk of that land loses soil at a rate of 20 to 40 tons per hectare every year.
The more plants covering the ground in damaged savanna pastures in Brazil, the less soil gets washed away — and plants explain a big chunk of why some areas lose more soil than others.
