The study has taken place in Etosha National Park whereby the behaviour and effect of giraffe on the flora was considered. The population of Etosha giraffe is a about 1800, which is high in the presence of other browsers. A lot of trees are pressurized by giraffe and a lot of individual tree spp are uprooted by elephants. The giraffe move from one place to another looking for food. The animals reconnaissance the area before they approach the waterhole. Much time is spent at the waterhole before and after drinking. The long neck and legs od this animal give it a special height which enable it to avoid competition for food with other browsers.
