Posted (edited)

The majority of the world's terrestrial large carnivores have undergone substantial range contractions and many of these species are currently threatened with extinction.

 

the study found the following reductions for Africa

 

  • Ethiopian wolf 99.3%
  • lion 93.7%
  • wild dog 92.2%
  • cheetah 91.5%
  • leopard 79.4%
  • hyneas  brown 27.2% spotted 24% and striped 15.1%

the study notes that the growth of cropping and cattle raising is associated with the decline of predators

such large reductions are very disturbing , being able to put a number on it might motivate more being done to assist 

 

only 8% of Africa  is occupied by carnivore guilds, groups who use the same resources
