Grasslands are one of the world's most extensive terrestrial biomes and are central to the
survival of herders, their livestock and diverse communities of large wild mammals,–. In …

Herbivory is a key process structuring vegetation in savannas, especially in Africa where
large mammal herbivore communities remain intact. Exclusion experiments consistently …

African savannas are undergoing management intensification, and decision makers are

In most terrestrial ecosystems, plant growth is limited by nitrogen and phosphorus. Adding
either nutrient to soil usually affects primary production, but their effects can be positive or …

We evaluated the impact of 7 years of grazing exclusion on vegetation and belowground
