The vegetation in Khaudum National Park is diverse, with a mix of tall and short dry forests, as well as acacia forests. The tall dry forest is species-rich and can reach up to 10 meters in height, with a dense undergrowth. Trees in this area include Pterocarpus angolensis, Baikiaea plurijuga, Burkea africana and Guibourtia coleosperma. In contrast, the trees in the lower forest are shorter, reaching less than 5 meters in height. The species range here includes Lonchocarpus neisii and Terminalia sericea, with Faidherbia albida and Grewia scattered throughout.
Along the Omuramba, the acacia dry forest is denser and is often filled with thorn bushes such as Acacia erioloba, Acacia fleckii, Acacia hebeclada, and Acacia tortilis. Combretum imberbe and Combretum hereroense can also be found in this area. The bed of the Omuramba is peaty and boggy, with dense Reed including Phragmites and, less commonly, water lilies. Terminalia prunioides, also known as blood fruit trees, are also prevalent in this area.
