There are two types: Valley Bushveld and Spekboomveld. These can be difficult to differentiate between. Generally this veld type occurs on the valley slopes and is characteristically very dense, 2-4m high vegetation, with an abundance of spiny and succulent species.

Although the spekboom (Portulacaria Afra) occurs in both types it dominates the Spekboomveld. Other characteristic species include the "boerboons" (Schotia Afra and Schotia Latifolia), "wildepruim" (Pappea Ccapensis), Plumbago Auriculata, and the tall cactus-like Euphorbia Grandidens. On the cooler southern slopes Aloe Speciosa with its drooping leaves can be often seen in fairly large numbers, while on the hot, dry northern slopes the "kerkei" Crassula Ovata, a squat succulent reaching a height of 1-1,5m occurs commonly.

Sub-tropical thicket is a very palatable and nutritious veld type and, as a result, where it occurs (or in close proximity) is where the visitor is likely to see the most game. It appears to be unique in that it is the only veld type known in the world to be driven by the action of large herbivores. In other words, in order to survive in a healthy state it needs to be browsed.

As a whole, this veld type has been decimated by goat farming and herein lies the paradox. Goats feed from the bottom up and in so doing prevent the spekboom from reproducing vegetatively.  The dense, more or less impenetrable, veld gets opened up so that more sun reaches the ground.

The seeds of many sub-tropical thicket plants require the shade and protection provided by parent plants in order to germinate and survive their early growth phase when they are most vulnerable and this opening up of the vegetation reduces germination and survival. However, due to their different feeding habits, indigenous browsers such as kudu, bushbuck and elephant, have the opposite effect.

They tend to feed from the top down. This encourages low level growth of the spek boom, which subsequently spreads out. The branches which then come into contact with the soil surface readily take root. These processes help maintain the correct micro climate for seed germination of the other Sub- tropical thicket species.

Examples of this veld type can be seen along the road in the Doornkraal - Grasnek area.
