Livestock grazing has minimal effect on the species richness and diversity of semi-arid shrubland in the Western Little Karoo, South Africa
Autor: Hannes Botha, Nelmarie Saayman, Craig D. Morris
Publikováno v: African Journal of Range and Forage Science; Vol 33, No 4 (2016); 225-233
The Succulent Karoo, one of two arid biodiversity hotspots in the world, is known for its high plant species richness, but little is known about the influence of topography and how it mediates the potentially deleterious effects of grazing. Changes i
