Detailed explanation-1: -Rinderpest had been suppressing the populations, but once the vaccination program eliminated the disease in cattle, rinderpest also disappeared from Serengeti’s wildlife. And that’s when the buffalo and wildebeest boomed.
Detailed explanation-2: -Rinderpest is a viral disease that infects cattle, wildebeest, and other hoofed animals. The disease had affected cattle and wildlife in the Serengeti region for decades. Death rates were extremely high, especially among wildebeest calves.
Detailed explanation-3: -A decade ago researchers attributed decreasing fires within Tanzania’s Serengeti National Park to the recovery of wildebeest herds following an epidemic of rinderpest, a viral disease.
