    Surplus woody plants in areas where there is bush thickening present an opportunity to harvest the wood as bio-fuel. The health of the ecosystem and rangeland restoration must, however, always be prioritised during any tree harvesting for bio-fuel.

    Ecosystems are a form of natural capital. Invasions by introduced alien plant species alter ecosystems, often reducing supplies of valuable ecosystem goods and services and imposing substantial costs on South Africa’s economy.

However, the high costs can be offset by the benefits of creating employment opportunities through such operations and the livelihood benefits that can be derived from the cleared land.
