Herbivores Return, Kenyan Savanna Tree Cover Drops
Times of India · science
For 18 years, researchers excluded large herbivores from fenced plots in a Kenyan savanna, observing a significant increase in tree cover and height. When fences were removed in 2017, allowing elephants and giraffes to return, tree cover rapidly declined. Within years, tree cover returned to pre-experiment levels, though tree density remained higher. The study published in Ecology Letters indicates that the presence of large herbivores significantly impacts savanna vegetation structure and growth.
