[ 2 ] 23,420 species of vascular plant have been recorded in South Africa, making it the sixth most species-rich country in the world and the most species-rich country on the African continent.
Sheep and goats are both small ruminants with cosmopolitan distributions due to their being kept historically and in modern times as grazers both individually and in herds in return for their production of milk, wool, and meat.
