Bush control for rangeland restoration, with or without engaging in the wood value chain for a supplementary income or the use of bush for a drought survival feed, is increasingly practiced in Namibia. This has resulted in an increase in the wood and wood product industry in Namibia. To assist landowners and improve the sustainability of the biomass industry, the De-bushing Advisory Services (DAS) initiated the development of a user-friendly standard model for estimating bush biomass in Namibia. The initiative was funded by the Bush Control and Biomass Utlisation project implemented by the Deutsche Gesellschaft für Internationale Zusammenarbeit (GIZ) GmbH in close cooperation with the Ministry of Environment, Forestry and Tourism (MEFT). It was conducted by rangeland experts, Mr. Jerome Boys of the Namibian Ministry of Agriculture, Water and Land Reform (MAWLR) and Professor Nico Smit of the University of Free State in South Africa. Its core aim was to develop an excel based model on three commonly harvested woody species (Terminalia sericea, Senegalia mellifera, Vachellia reficiens). This base model will have the ability to be expanded over time with the addition of regression equations for other species should the need arise.
