Will fences save Africa's lions?
The world's remaining lions are in trouble. There are simply too many humans hungry for the same land the majestic cats roam. The more the human population grows, the more the lion population plummets. Only fences can keep one species from killing the other, according to a leading lion researcher.
In fenced reserves such as South Africa's Kruger National Park, which is as large as the state of New Jersey, "the population of lions is doing just fine," Craig Packer, an ecologist at the University of Minnesota, told NBC News from his research site in Tanzania.
"However, that is just a small proportion of the total African population of lions. The vast majority of lions live in unfenced reserves and … the trends are pretty disturbing," he added.
Counting lions is notoriously difficult work. Current best estimates put the African population at around 35,000. Nearly half of the known populations in unfenced areas are declining to the point that within 20 to 30 years, they will be just 10 percent of their potential population, Packer said.
