The Succulent Karoo is notable for the world’s richest flora of succulent plants, and harbours about one-third of the world’s approximately 10,000 succulent species. 40% of its succulent plants are endemic. The region is extraordinarily rich in geophytes, harbouring approximately 630 species.
Consequently, what is a Succulent Karoo biome?
Succulent Karoo: An Arid Biodiversity Hotspot
At approximately 111 000 km in size, the Succulent Karoo is the fourth largest biome in southern Africa, smaller only than the savanna, Nama-Karoo and grassland biomes.
In this manner, what plants are found in the Succulent Karoo?
Notable plant species found in this hotspot include the botterboom (Tylecodon paniculatus), a stem succulent that has glossy leaves in winter and red flowers in summer, and the halfmens (“half human”) (Pachypodium namaquanum), a stem succulent endemic to the Richtersveld that can grow up to four meters tall.
What can the vegetation of the Succulent Karoo biome be described as?
The Succulent Karoo has a predominance of low, succulent-leaved shrubs, few grasses, and a scarcity of tall shrubs and trees. It is easily distinguished from its neighboring ecoregions by its climate, soils, and the resultant vegetation and flora.
The perennial plants survive the dry season by using water stored in the leaves or stems. These plants are called succulents. reducing the number of stomata. The non-succulent perennials have very small leaves to reduce water loss by transpiration.
Fog and dew may provide a vital source of moisture for many of the rare succulent shrubs that are limited to the fog belt along our arid West Coast.
Grasses are uncommon, making most of the biome unsuitable for grazing. The low rainfall, in fact, discourages most forms of agriculture. An exception is the thriving ostrich-farming industry in the Little Karoo, which is heavily dependent on supplementary feeding with lucerne.
To be classified as a biodiversity hotspot, a region must have lost at least 70 percent of its original natural vegetation, usually due to human activity. There are over 30 recognized biodiversity hotspots in the world. The Andes Mountains Tropical Hotspot is the world’s most diverse hotspot.
What are biodiversity hotspots? To qualify as a biodiversity hotspot, a region must meet two strict criteria: It must have at least 1,500 vascular plants as endemics — which is to say, it must have a high percentage of plant life found nowhere else on the planet. A hotspot, in other words, is irreplaceable.
