In a place where a lot of bare soil exists, old herder pen sites in the African Savannah which date between 1500 and 3700 years ago have turned into ecosystem ‘hotpockets’ that contain higher levels of nitrogen and mineral nutrients than other Savannah locales.
These hotspots, which were night-time holding corrals, have become concentrated, nutrient-dense grassy areas that are still drawing cards for wild and domestic herbivores today. Research states that herding practices of old have created rich ecological diversity in the Savannah.
