The springbok holds the record for having the largest antelope migration in history.

One afternoon in October 1946, the then warden of the 'Kalahari Gemsbok Park' Joep le Riche, encountered a mass of Sprinbok moving slowly through the Nossob riverbed.

He reported the column to be seven miles deep and to contain an estimated number of more than 15000 animals, further up the Nossob he encountered several more herds! A second, even larger trek was noted in November 1950.

What special adaptations do Sprinbok have that no other antelope possess, and what other factors are thought to have contributed to this explosion in numbers?

The springbok has several adaptations to enable a successful existence in the harsh, arid environment they inhabit:
1)They are opportunists in their feeding behaviour. During the hot, rainy summers, springbok primarily graze on grasses and turn to browsing on shrubs in the colder and drier winters. They are also fond of feeding on flowers when available, and when water is scarce springbok seek out moisture-rich roots, tubers and succulent foliage 2) Springbok will drink water whenever it is available, but also maintain their water balance by feeding at night, when the rise in humidity increases the water content of vegetation.
3)Springboks are opportunistic breeders and can breed year-round, often synchronising the birth of their young with periods of high rainfall when there is an abundance of green grass shoots to feed on.

These things make them durable and able to breed successively, with a low mortality rate amongst the herds.

I get better with age. I'm consumed although dead. I play a vital role in the survival of a species. Which tree am I referring to?

Welwitschia? Isn't there an ant species that is dependent upon it?

Apologies for forgetting this one!!

Thanks for the answer OWN :thumbs_up:

Another factor I found interesting; It is said that the Springbok reproduction rate is higher than any other antelope. Nearly every adult female produces a lamb each year, no matter how poor the conditions. In other antelope, dry conditions severely depress the pregnancy rate, if conditions are very good, six month old Sprinbok lambs may become pregnant and will lamb at just more than one year of age, when they are not yet full-grown. Furthermore, within days of lambing, a female may fall pregnant again, and thus produce two lambs in a 13-month period, other antelope can produce only one lamb per year.

Remember to indicate the dependent creature too. :wink:

Wow this is a stunning quiz. Have never been in here.

Just as a matter of interest my dad has slides with camels and wild dogs on. Must have taken them some where in the 70's. The camels were at twee rivieren and the wild dogs at samevloeiing.

Elzet don;t have the faintest idea of what tree you are talking about.

Hiya Lion Queen :dance: :dance: , why don't you join us in the quizzes. Sure Upington's night life leaves much to be desired... i.e. the street lights are not even on. :lol: :lol: :tongue: :tongue:


Camels were plentiful. I asked a related Q a while ago. Google camels Kalahari Gemsbok and see what it delivers. Most of them are now found in the South of Botswana, if I recall correctly. :redface: :redface:
