Invasive plants in Namibian subtropical and riparian woodland
Given that Namibia (Figure 20.1a) is one of the driest African countries south of the Sahara, this chapter may seem out of place in a book on invasive plants in forest ecosystems. However, based on the Food and Agriculture Organisation of the United Nations’ (FAO) deﬁnition of a forest as "an area covered by at least 10% canopy cover of trees higher than 5 meters and extending for more than half a hectare" (FAO 2000), slightly less than 10% of the country is estimated to be covered by forest (Mendelsohn and el Obeid 2005). This ﬁgure excludes numerous riparian forests along perennial and ephemeral rivers.
