This biome stretches from the west coast of Kwazulu Natal, with the largest part situated in the Eastern cape.

CLIMATE:TEMPERATURE RANGE

The climate is dry, especially as one proceeds inland, but the shady valleys are cooler than the surrounding terrain which is hot in summer and cold in winter and receives irregular rainfall, it varies because it extends over a large area.

TYPES OF SOIL.

Subtropical thicket occupies landscapes of both poor and fertile soils, and variable topographic position. It occurs in areas receiving a wide range of annual rainfall (between 200-950 mm per annum). Often the soil is shallow and varies from sandy to clay soil that is rich in lime.

VEGETATION.

-The vegetation varies from shrubland to low forest with many evergreen and succulent trees and shrubs.

-Many of the plants have thorns.

-Examples of plants that occur  here in includes the spekboom (pork bush), Euphorbia, Cape honeysuckle and plumbago.

ANIMAL LIFE.

-The African Elephant, Kudu, Vervet monkey and bushbuck , hares, Aardvark, Topi, mice, impala , Lions, Hyenas and leopards are some of the animals you’d find in this biome.

Geography-landscape.

They are found on steep slopes of deeply incised rivers as well as undulating to steep hills and their valleys.

THREATS, CAUSES, AND EFFECTS.

The Subtropical thicket biome is driven largely by disturbance processes, notably drought and flood, and particularly herbivory and fire , to which the vegetation has evolved an amazing resilience.

The climate is dry, especially as one proceeds inland, but the shady valleys are cooler than the surrounding terrain which is hot in summer, cold in winter and receives irregular rainfall.

SPHERE AFFECTED.

With droughts, the biosphere is affected, all living organisms need water to survive. Not only is the biosphere affected but the drought also affects the hydrosphere , because there is no or lack of water, because the air is not so moist the air seems thinner which would affect the atmosphere and the lithosphere which the ground will also have less moisture and wil be dry.
