Hwange National Park (formerly
Wankie Game Reserve) is the largest game reserve in Zimbabwe. The park lies in the west, on the main road between
Bulawayo and the widely noted
Victoria Falls and near to
Dete.
Flora
=======
The park is close to the edge of the
Kalahari desert, a region with little water and very sparse, xerophile vegetation. The
Kalahari woodland is dominated by
Zambezi Teak,
Sand Camwood (Baphia) and Kalahari bauhinia.[9] Seasonal wetlands form grasslands in this area.
The north
and north-west of the park are dominated by mopane woodland.
Although it has been argued that elephant populations cause change in vegetation structure, some recent studies suggest that this is not the case, even with the large increases in elephant population recorded in the late
1980s.
Fauna
========
The Park hosts over
100 mammal and 400 bird species, including 19 large herbivores and eight large carnivores. All Zimbabwe's specially protected animals are to be found in
Hwange and it is the only protected area where gemsbok and brown hyena occur in reasonable numbers.
Grazing herbivores are more common in the
Main Camp Wild Area and Linkwasha Concession Area, with mixed feeders more common in the
Robins and Sinamatella Wild Areas, which are more heavily wooded.
Distribution fluctuates seasonally, with large herbivores concentrating in areas where intensive water pumping is maintained during the dry season.
The population of
African wild dogs to be found in Hwange is thought to be of one of the larger surviving groups in
Africa today, along with that of
Kruger National Park and
Selous Game Reserve. Other major predators include the lion, whose distribution and hunting in Hwange is strongly related to the pans and waterholes, leopard, spotted hyena and cheetah.
Elephants have been enormously successful in Hwange and the population has increased to far above that naturally supported by such an area.[19] This population of elephants has put a lot of strain on the resources of the park. There has been a lot of debate on how to deal with this, with parks authorities implementing culling to reduce populations,[20] especially during 1967 to
1986. The elephant population doubled in the five years following the end of culling in 1986.
National Parks Scientific Services co-ordinates two major conservation and research projects in the park:
National Leopard Project, which is surveying numbers of leopard to obtain base-line data for later comparative analysis with status of leopard in consumptive (hunting) areas and Communal
Land bordering the
National Park. This is carried out at Hwange in conjunction with the
Wildlife Conservation and
Research Unit of
Oxford University and the Dete
Animal Rescue Trust, a registered wildlife conservation Trust
Painted Dog Project:
The project aims to protect and increase the range and numbers of
African wild dog both in Zimbabwe and elsewhere in
Africa, and operates through the
Painted Dog Conservation organisation in Dete.
Geography and geology
======================
Most of the park is underlain by Kalahari Sands
. In the north-west there are basalt lava flows of the
Batoka Formation, stretching from south of Bumbusi to the
Botswana border. In the north-central area, from Sinamatella going eastwards, there are granites and gneisses of the Kamativi-Dete
Inlier and smaller inliers of these rocks are found within the basalts in the north-west.
The north and north-west of the park are drained by the
Deka and Lukosi rivers and their tributaries, and the far south of the park is drained by the Gwabadzabuya
River, a tributary of the
Nata River. There are no rivers in the rest of the park, although there are fossil drainage channels in the main camp and Linkwasha areas, which form seasonal wetlands. In these areas without rivers, grassy pan depressions and pans have formed. Some of these pans, such as many of the pans in the
Shumba area, fill with rainwater, while others, such as Ngweshla, Shakwanki and Nehimba, are fed by natural groundwater seeps. Many of the pans are additionally supplied by water pumped from underground by park authorities.
