AB Traditional approaches to biodiversity conservation focused on protection of natural habitats in parks and reserves while neglecting the potential to conserve agrobiodiversity in farming systems that could provide other direct and indirect benefits necessary for livelihoods and ecosystem functioning. Quantitative assessments of tree biodiversity have mostly focused on traditional production systems such as shifting cultivation in the miombo ecozone, home gardens and the parkland systems; and to a lesser extent the below ground biodiversity with respect to micro flora and fauna as a function of soil fertility improvement. Agroforestry systems, in contrast to intensive monocultures, may provide high quality habitats for biodiversity conservation. In the case of trees on the landscape, the use of non-timber forest products as a livelihood strategy, particularly for food, nutrition, medicine and'safety net' during lean periods, has been one of the drivers of biodiversity conservation. In southern Africa, research that has addressed biodiversity albeit indirectly include indigenous fruit tree domestication and the screening of multi-purpose tree germplasm for improved agroforestry systems and/or technologies. This paper highlights the state of knowledge on the contribution of agroforestry to agrobiodiversity in southern Africa. It draws on the huge body of data on the genetic diversity of agroforestry trees used to meet diverse livelihood needs including those used for soil fertility replenishment, provision of animal fodder, fruits, medicinal products and, fuelwood and timber.
