Encroacher bush species threatens Namibia’s rangeland, resulting reduced carrying capacity of land. The WML Consulting Engineers through the GIZ Support to De-bushing Project compiled a summary of five harvesting technologies for encroacher bush in Namibia with emphasis on harvesting Namibia encroacher bush with environmental considerations. The identified methods for bush harvesting and thinning include manual to semi mechanised, biological, chemical application by hand and medium to large-scale mechanised operations. Manual to semi mechanised is suitable for small operations using small hand-held or power operated tools, to fell and chop down bushes and trees. This method requires follow-up to avoid cut stumps or buds from coppicing. Biological control is natural means of bush control through fungal related die backs, controlled fires and browsing.
Mechanised method consists of medium to large-scale mechanised operations equipment which aims to quickly harvest the biomass (e.g. bull dozers, excavators) for bush clearing. Bush harvesting operations requires constant aftercare to prevent regrowth. All harvesting methods selected should incorporate bush thinning principles as stipulated in the Forestry and Environmental guidelines
