From that point there was a steady rise in the quantity of elephants and the other beasts, however the first one and zebras recovered slightly during 1983. The giraffes represented the clear gradual decrease till the end of the period. Furthermore, there was a complete extinction of the rhinos after 1986. Interestingly, the sum of giraffes was half of the amount of the starting, which remains 2235 and then dropped to 1559. At the end the amount of zebras was much more than the other species including the quota of ostriches.
