Promoting Sustainable Management of the Miombo Woodlands : Policy Brief 2 (English)

The timber harvesting in the Miombo region involves selective harvesting of preferred timber species (such as Pterocarpus angolensis, Afzelia angolensis, Dalbergia melanoxylon) without opening up of the woodland. Selective harvesting decreases the likelihood of conspecific replacement and increases the risk of collapse of the natural successional pathway. This method is unsustainable in that it does not support recruitment of timber species, as these species are light demanders. This has the ability to result in total collapse of the population that are being harvested if the situation persists for a long time as there will be no recruitment with time into the higher size class when individuals die. To ensure sustainable harvesting, policymakers across the region must take into account a number of factors, including: development and implementation of woodland management plans based on growth rates of timber species. This should provide for regulation of initial harvesting and subsequent cutting cycles; silvicultural prescriptions for major vegetation types and species based on their functional traits and disturbance factors; and integrated silvicultural systems that accommodate different commercial applications (for example, charcoal, timber, honey).
