biologically, with 7 major distinct terrestrial biomes, one of which, the Cape Floral Kingdom, is endemic to the region. This biodiversity is, however, under threat due to land expansion, climate change, alien species invasion and much more (Turpie 2013). The loss of ecological settings and species demands that biodiversity should be protected by a variety of management efforts. Traditionally, the protection of biodiversity was reserved for local communities, government agencies, and welfare…

includes diversity within species, between species and of ecosystems themselves. Floristic diversity refers to the variety and variability of plants in a region. Floristic structure is considered as one of the major exceptional characters of the community (Dansereau, 1960) and therefore any disturbances in phytodiversity is projected to change the community organization. It is considered to be the vital component of ecosystem (Hutchinson,…

fact that the earth as we know it has proceeded through 5 “waves” of mass extinctions, and is currently in the middle of yet another wave of mass extinction (the sixth). These “unnatural” occurrences have displayed shocking changes to the variety of species on the globe, hence the title: “The Sixth Extinction, An Unnatural History.” 2. What gave people the idea that organisms may have gone extinct because of catastrophes? The term extinction didn’t really exist until the early 1800s,…
