Comprehensive South African Survey Finds Only 83 Mature Free-Roaming Cheetahs
According to Mongabay, researchers conducting the Free-Roaming Cheetah Census mapped nearly 100,000 square kilometers of South Africa and discovered only 83 mature adult cheetahs. The survey highlights significant threats to the species, including habitat fragmentation from farming, construction, and fences, as well as retaliatory killings by farmers. While cheetahs are currently listed as vulnerable, the census suggests they should be reclassified as endangered within South Africa.
Key points
- Researchers mapped nearly 100,000 square kilometers (about 40,000 square miles) in South Africa.
- The Free-Roaming Cheetah Census located only 83 mature adult cheetahs in the surveyed region.
- Unprotected cheetahs move across borders between South Africa, Botswana, Namibia, and Zimbabwe.
- Farming, fences, construction, and retaliatory killings by farmers pose major threats to the population.
- The census suggests reclassifying South Africa's cheetahs from vulnerable to endangered.
What happened
A comprehensive survey known as the Free-Roaming Cheetah Census mapped almost 100,000 square kilometers, or nearly 40,000 square miles, of South Africa and found just 83 mature adult cheetahs, as reported by Mongabay. The project represents the most thorough survey of cheetahs ever conducted in the region.
Context
Free-roaming cheetahs in the area naturally cross borders between South Africa, Botswana, Namibia, and Zimbabwe. However, expanding development, construction, farming, and fences are increasingly obstructing their movement. These vast landscapes are essential for cheetah survival to prevent the loss of genetic diversity through isolated groups.
Additionally, farmers sometimes kill cheetahs out of concern that the cats prey on livestock, though researchers found that cheetahs primarily hunt wild prey. Although the species currently holds a vulnerable status, the census findings suggest that cheetahs should be reclassified as endangered in South Africa.
What's next
The survey findings raise questions about future conservation policies and whether official status classifications for cheetahs in South Africa will be updated to reflect the reported population decline and habitat challenges.
Why it matters
The survey provides critical baseline data on free-roaming cheetah populations in South Africa, highlighting severe habitat fragmentation and human-wildlife conflict that threaten the species' long-term genetic viability.
What we know
- Researchers mapped almost 100,000 square kilometers (nearly 40,000 square miles) of South Africa.
- The Free-Roaming Cheetah Census found 83 mature adult cheetahs in the surveyed area.
- Unprotected cheetahs move between South Africa, Botswana, Namibia, and Zimbabwe.
- Farming, construction, development, and fences hinder cheetah movement and genetic mixing.
- Farmers sometimes kill cheetahs due to beliefs that they prey on livestock.
- Researchers found that cheetahs hunt mostly wild prey.
