SAVUTE
CHANNEL & MARSH
Botswana
Savute Channel & Marsh
Recognised as a prime game viewing area, the Savuti (also spelt
Savute), covers almost 1,930 sq. miles (5,000 square km) in the
south west of Chobe National Park. The western edge of Savuti is
encircled by the Magwikhwe sand ridge, 156 miles (100km) long and
65 feet (20 metres) high, which is the ancient shoreline of a super-lake
that covered much of northern Botswana. It is difficult to imagine
that this harsh dry landscape was once submerged beneath an enormous
inland sea.
A channel from the Linyanti River once fed the now dry Savuti Marsh,
which is the deepest part of the Mababe Depression and is the only
part to have filled with water in recent history.
This marsh has something of a mystical renown as it can dry up
or flood regardless of local rains. David Livingstone, on his way
to 'discover' the Victoria Falls in 1851, commented, that it was
a "dismal swamp," but sometime around 1888 it started
to dry up and remained completely parched until 1957. Camelthorn
acacia trees established themselves in the channel and along the
banks and grew to full size. During unexpected floods these trees
were drowned but as the channel and marsh dried out again, the dead
trees became one of the most prominent features of the landscape.
Today, parts of Savuti are almost desert-like with a scorching
sun and hot sand, while at the other extreme are vast grass plains
full of game, reminiscent of Tanzania's Serengeti. These rich grasslands
are boosted into fecundity by summer rains, at which time huge herds
of zebras migrate south from the Linyanti to gorge on the abundant
grazing. Savuti also contains a number of pans that hold water for
months after the rains, enabling animals to remain long into the
dry season.
Another strikingly different terrain found in Savuti, are the Gubatsa
Hills. Formed some 980 million years ago during volcanic movement,
these dolomite rock outcrops create a series of extraordinary hills.
They rise to an astonishing 290 feet (90 metres) high, out of a
completely flat landscape.
Game Viewing
The area promises sightings of endangered wild dog, which is said
to be the most efficient hunter in Africa. Large concentrations
of lion follow the annual zebra migration intently, and leopard
and cheetah are to be seen. Many hyenas live here and researchers
have found that lions loose 20% of their kills to them. Hyenas are
formidable hunters in their own right but are opportunistic feeders
who will annoy and threaten a pride of lions until they give up
their meal. Savuti is also famous for its elephants that roam great
distances for the best fodder.
Large secretary birds and kori bustards are often seen strutting
around the Savuti marsh and small redbilled francolins provide as
a noisy morning wake up call. Interesting summer migrants and water
birds include Abdim's storks, carmine bee eaters and even fish eagles.
Little quelea finches are quite a spectacle as they gather in thousands.
They reach a frenzy of numbers in about April when a single flock
could contain tens of thousands of these small twittering birds.
Seasons
Rainy season: Rains arrive from November to April,
at which time the animals make their way to pastures rich in new
grass. Sometime in November or December thousands of zebras migrate
from the Linyanti in the north and move south through Savuti to
the grasslands of the Mababe Depression. In February they start
heading northwards again. Humidity and heat is high.
Dry season: From May to October the water pans
dry up and the animals are attracted to three artificial waterholes.
Elephants dominate these while other animals have to wait their
turn. September and October can be extremely hot but game viewing
is very rewarding as predators are concentrated around the waterholes.
