Scientists Call for Cheetahs to Be Listed as Endangered
A year ago, scientists reported that cheetahs had disappeared from across 91 percent of their historic range.
The cheetah (Acinonyx jubatus), the researchers recommended in their study, should be up-listed from Vulnerable to Endangered on the IUCN Red List of Threatened Species. Doing this could afford the imperiled species greater attention and support, they said.
The cheetah, however, remains officially listed as Vulnerable on the IUCN Red List.
Now, in a new study, scientists have called for up-listing the species to Endangered yet again.
By analyzing millions of cheetah observations, a team of researchers have concluded that only about 3,577 adult cheetahs remain in southern Africa–within an area of 789,800 square kilometers across Namibia, Botswana, South Africa and Zimbabwe. More than 55 percent of these cheetahs live in Namibia alone, the researchers reported in the study published in the journal PeerJ.
"This is the area with the largest population of free-ranging cheetahs left on Earth," lead author of the study Varsha Vijay of Duke University said in a statement. "Knowing how many cheetahs there are and where they occur is crucial for developing suitable conservation management plans for the species."
The researchers also estimate that there could be an additional 3,250 cheetahs living in potential habitat areas, or places where cheetahs can possibly live but where they have not been observed recently. But the team has lower confidence in this estimate. "We know about three and a half thousand cheetahs. There could be twice as many, but we can't prove it," Florian Weise of the U.S.-based conservation group Claws Conservancy, also a lead author of the study, told National Geographic news.

Of the 3,577 known cheetahs, less than 50 percent live inside some form of protected area, such as Kruger National Park in South Africa, the study estimates. The rest live on unprotected lands, mostly allocated for livestock or game production. Many farmers who share their land with cheetahs, consider the animals to be a source of conflict, the researchers found. While only a few resort to actually killing or trapping the animals, the researchers say that persecution by even a few farmers can cause cheetah populations to decline.
"The future of the cheetah relies heavily on working with farmers who host these big cats on their lands, bearing the heaviest cost of coexistence," said Weise.
Given that the study's population estimate for the cheetah is 11 percent lower than the IUCN's current assessment for the same region, the authors write that the species should be urgently up-listed from Vulnerable to Endangered status. This revision of status could help conservationists create more awareness about the species and "open more avenues to fund conservation and population monitoring efforts," they said in the statement. This study was supported by the National Geographic Society's Big Cats Initiative.

A total of 563 square kilometers (217.38 square miles) of the world's largest rainforest was destroyed in November, 103% more than in the same month last year, according to Brazil's space research agency.
From January to November this year an area almost the size of the Caribbean island of Puerto Rico was destroyed — an 83% overall increase in destruction when compared with the same period last year.
The figures were released on Friday by the National Institute for Space Research (INPE), and collected through the DETER database, which uses satellite images to monitor forest fires, forest destruction and other developments affecting the rainforest.
What's Behind the Rise?
Overall, deforestation in 2019 has jumped 30% compared to last year — 9,762 square kilometers (approximately 3769 square miles) have been destroyed, despite deforestation usually slowing during November and December.
Environmental groups, researchers and activists blamed the policies of Brazil's president Jair Bolsonaro for the increase.
They say that Bolosonaro's calls for the Amazon to be developed and his weakening support for Ibama, the government's environmental agency, have led to loggers and ranchers feeling safer and braver in destroying the expansive rainforest.
His government hit back at these claims, pointing out that previous governments also cut budgets to environment agencies such as Ibama.
AOSIS blasted Brazil, among other nations, for "a lack of ambition that also undermines ours."
Last month, a group of Brazilian lawyers called for Bolsonaro to be investigated by the International Criminal Court over his environmental policies.

The Carolina parakeet, the only parrot species native to the U.S., went extinct in 1918 when the last bird died at the Cincinnati Zoo. Now, a little more than 100 years later, researchers have determined that humans were entirely to blame.

In 2017 the Thomas fire raged through 281,893 acres in Ventura and Santa Barbara counties, California, leaving in its wake a blackened expanse of land, burned vegetation, and more than 1,000 destroyed buildings.
