The zebra is an iconic symbol of the African savanna, instantly recognizable by its distinctive black and white stripes. Determining a single global population count is not possible because the term “zebra” encompasses three distinct species, each with unique geographical ranges and conservation challenges. These species have experienced vastly different population trends, meaning their overall number is an aggregate of separate biological realities. Focusing on the status of each individual species provides a more accurate picture of their survival prospects.
The Three Zebra Species
The three extant species of zebra—the Plains, Grévy’s, and Mountain zebra—are classified within the genus Equus, but they exhibit clear differences in appearance and social structure. The Plains zebra (Equus quagga) is the most common and geographically widespread, ranging across eastern and southern Africa. This species is characterized by its broad stripes that often fade to a grayish-brown on the hindquarters and extend onto the belly.
The Grévy’s zebra (Equus grevyi) is the largest of the three species and is found exclusively in the semi-arid grasslands of northern Kenya and southern Ethiopia. It is easily distinguishable by its narrow, closely set stripes, large, rounded ears, and white belly. The Mountain zebra (Equus zebra), confined to the rugged, mountainous regions of southwestern Africa, is the smallest species and includes two recognized subspecies: the Cape Mountain zebra and the Hartmann’s Mountain zebra.
Global Population Status and Conservation
The total number of zebras in the world is estimated to be over half a million, but this figure is heavily skewed by the Plains zebra population. The Plains zebra is the most numerous, with a total population estimated to be between 500,000 and 660,000 individuals. Despite its relative abundance, the Plains zebra is currently classified as Near Threatened by the International Union for Conservation of Nature (IUCN) because its population is declining in over half of the 17 countries where it is native.
The most threatened is the Grévy’s zebra, which has experienced a severe population collapse of more than 80% since the late 1970s. Current estimates place its total wild population at only around 2,800 to 3,000 individuals, primarily distributed across Kenya and Ethiopia. This catastrophic decline has resulted in the species being listed as Endangered on the IUCN Red List.
The Mountain zebra presents a conservation success story, though the species as a whole is classified as Vulnerable. The Cape Mountain zebra (E. z. zebra) population has rebounded remarkably from fewer than 100 individuals in the 1950s to over 2,700 animals today, leading to its reclassification as Least Concern. The Hartmann’s Mountain zebra (E. z. hartmannae), found mainly in Namibia, has a much larger population, estimated at over 30,000 mature individuals. Its population trend is less certain and requires ongoing assessment.
Primary Drivers of Population Change
Habitat loss and fragmentation represent the greatest challenge to zebra populations across all species. Agricultural expansion and increasing human settlement reduce available grazing land and disrupt traditional migration routes. This encroachment forces zebras into smaller, isolated patches of habitat, increasing their vulnerability to localized threats.
Competition with domestic livestock, particularly cattle and goats, places pressure on food and water resources. This competition is acute in the arid rangelands of the Grévy’s zebra, where overgrazing degrades the ecosystem and limits access to water sources. Drought conditions, exacerbated by climate change, further intensify this struggle.
Illegal poaching remains a persistent threat, especially outside of protected areas. Zebras are hunted for their meat (sold as bushmeat) and their hides (valued for leather goods). In some regions, body parts are used in traditional medicine, contributing to the illegal targeting of these animals.
Ongoing Conservation and Recovery Efforts
Conservation efforts are highly specialized, focusing on the distinct needs of each species and local population. For the Grévy’s zebra, community-based programs are effective because over 90% of the population lives outside national parks. These programs incentivize local communities to manage and protect the zebras by linking wildlife protection with socio-economic benefits.
Protected area management is the primary strategy for the Plains and Mountain zebra populations. This involves rigorously enforcing anti-poaching laws and managing grazing resources to minimize conflict with pastoralists. Translocation programs, moving zebras to new, safe habitats to establish new populations, have been a powerful tool in the recovery of the Cape Mountain zebra.
Genetic diversity is also actively managed, particularly for the smaller, isolated populations of Mountain zebras, through metapopulation management strategies. These efforts aim to ensure the long-term viability of the species by preventing inbreeding and maintaining genetic health. These focused, collaborative efforts provide the most promising path toward stabilizing and recovering threatened zebra populations across Africa.
