Chobe National Park

Chobe National Park is Botswana's first national park, and also the most biologically diverse. Located in the north of the country, it is Botswana's third largest park, after Central Kalahari Game Reserve and Gemsbok National Park, and has one of the greatest concentrations of game in all of Africa.
This park is noted for having a population of lions which prey on elephants, mostly calves or juveniles, but also subadults.
History.
The original inhabitants of this area were the San bushmen (also known as the Basarwa people in Botswana). They were nomadic hunter-gatherers who were constantly moving from place to place to find food sources, namely fruits, water and wild animals. Nowadays one can find San paintings inside rocky hills of the park.
At the beginning of the 20th century, the region that would become Botswana was divided into different land tenure systems. At that time, a major part of the park's area was classified as crown land. The idea of a national park to protect the varied wildlife found here as well as promote tourism first appeared in 1931. The following year, around Chobe district were officially declared non-hunting area; this area was expanded to two years later.
In 1943, heavy tsetse infestations occurred throughout the region, delaying the creation of the national park. By 1953, the project received governmental attention again: were suggested to become a game reserve. Chobe Game Reserve was officially created in 1960, though smaller than initially desired. In 1967, the reserve was declared a national park.
At that time there were several industrial settlements in the region, especially at Serondela, where the timber industry proliferated. These settlements were gradually moved out of the park, and it was not until 1975 that the whole protected area was exempt from human activity. Nowadays traces of the prior timber industry are still visible at Serondela. Minor expansions of the park took place in 1980 and 1987.
Geography and ecosystems.
The park can be divided up to 4 areas, each corresponding to one distinct ecosystem:
Elephant concentration.
The park is widely known for its large elephant population, estimated to be around 50,000. Elephants living here are Kalahari elephants, the largest in herd size of all known elephant populations. They are characterized by rather brittle ivory and short tusks, perhaps due to calcium deficiency in the soils. Damage caused by the high numbers of elephants is rife in some areas. In fact, the concentration is so high throughout Chobe that culls have been considered, but are too controversial and have thus far been rejected by park management. In the dry season, these elephants sojourn in the Chobe River and Linyanti River areas. In the rainy season, they make a 200-kilometre migration to the south-eastern stretch of the park. Their distribution zone however outreaches the park and spreads to north-western Zimbabwe.
Roads.
Road conditions in Chobe National Park depend greatly on the season and rainfall; one needs a 4x4 vehicle to travel in the Park. Thick sand becomes a problem in the Chobe River Front during the dry months, particularly as the temperature rises and during the wet season the roads near the river become muddy.
Savuti.
Savuti roads, mainly the western Sandridge Road from Mababe Gate and the roads both north and south of the Savuti channel are typically thick sand and tricky to drive. When rain has fallen, driving along the marsh roads, as the wet black cotton soil becomes unnavigable, carries the risk of getting stuck.
Nogatsaa.
Nogatsaa roads are waterlogged during the wet months and very little of the road network can be driven at this time. During the dry months, game drives from one pan to the next are on roads with small, thick sandy patches. Once leaving the tar road from Kasane, people would have to drive through thick sand for the first , before reaching a sand road.
