Grevy’s Zebras live in arid and semi-arid grass and shrubland where they can gain access to permanent water. They are extremely mobile and move distances of greater than 80 km. in search of water. Hence when pastoral livestock monopolize water, Grevy’s Zebras suffer. Grevy's Zebra suffered declines from a global population of around 15,600 to around 2,000 individuals in 2004. Since then there have been some signs of population recovery.
