Only the border with Botswana and a 55-km section of the western border of the park are fenced in the Khaudum National Park. This open-park system ensures that wildlife can pursue hereditary migratory routes to and from the water-rich Kavango River and floodplains, including the Okavango Delta, a mere 150 km from the park boundary. Thus wildlife migratory routes link Namibia, Botswana and Angola under a protective legislative coat. In addition, the Khaudum is the only park in Namibia that protects the Northern Kalahari Sandveld biome, portrayed as forest savannah and woodland.
