Victoria falls is one of the Seven Natural Wonders of the World. David Livingstone, the Scottish explorer, is believed to have been the first European to view the Victoria Falls.
While it is neither the highest nor the widest waterfall in the world, it is claimed to be the largest. This claim is based on a width of 1,708 metres (5,600 ft) and height of 108 meters (360 ft), forming the largest sheet of falling water in the world. The falls' maximum flow rate compares well with that of other major waterfalls (see table below).
The two national parks at the falls are relatively small - Mosi-oa-Tunya National Park is 66 square kilometres (16,309 acres) and Victoria Falls National Park is 23 square kilometres (5,683 acres). However, next to the latter on the southern bank is the Zambezi National Park, extending 40 kilometers (25 mi) west along the river. Animals can move between the two Zimbabwean parks and can also reach Matetsi Safari Area, Kazuma Pan National Park and Hwange National Park to the south.
On the Zambian side, fences and the outskirts of Livingstone tend to confine most animals to the Mosi-oa-Tunya National Park. In addition fences put up by lodges in response to crime restrict animal movement.
Mopane woodland savannah predominates in the area, with smaller areas of Miombo and Rhodesian Teak woodland and scrubland savannah. Riverine forest with palm trees lines the banks and islands above the falls. The most notable aspect of the area's vegetation though is the rainforest nurtured by the spray from the falls, containing plants rare for the area such as pod mahogany, ebony, ivory palm, wild date palm and a number of creepers and lianas. Vegetation has suffered in recent droughts, and so have the animals that depend on it, particularly antelope.
The national parks contain abundant wildlife including sizable populations of elephant, buffalo, giraffe, zebra, and a variety of antelope. Lion and leopard are only occasionally seen. Vervet monkeys and baboons are common. The river above the falls contains large populations of hippopotamus and crocodile. Elephants cross the river in the dry season at particular crossing points.
Klipspringers and clawless otters can be glimpsed in the gorges, but they are mainly known for 35 species of raptors. The Taita Falcon, Black Eagle, Peregrine Falcon and Augur Buzzard breed there. Above the falls, herons, Fish Eagles and numerous kinds of waterfowl are common.
The river is home to 39 species of fish below the falls and 89 species above it, mostly black cod and slippery trout. This illustrates the effectiveness of the falls as a dividing barrier between the upper and lower Zambezi.
