Growing season, mid-rainfall subtropical savanna in Entre Rios, Argentina. These mid-rainfall areas have somewhat lower productivity than the really high-rainfall areas. Consequently, plants typically need longer recovery periods between grazings.

Lower biological productivity also means grass plants accumulate less lignin, are therefore higher in nutritive quality, and are less physically difficult to break down and lay on the soil surface. Ultra-high stock densities and extreme levels of animal impact therefore become less critical than in higher producing brittle savannas.
