oa Madoqua - Population structure, mortality patterns and a predictive model for estimating future trends in wildebeest numbers in the Etosha National Park
Following a decline in the wildebeest population From 25 000 to 2 500 between 1954-78 it was established that the calving percentage was normal (22% of total population) but that disproportionate mortality, favouring the cows, resulted in 48% of recorded deaths between 3-6 years of age. By 10 years of age 91% of all adults had died. Disease, namely anthrax and abnormal predation levels caused this high death rate.
