Western Black Rhino Officially Extinct

Western Black Rhino Officially ExtinctAfrica’s western black rhino is now officially extinct according the latest review of animals and plants by the world’s largest conservation network.

‘Making its last stand’

The subspecies of the black rhino — which is classified as “critically endangered” by the International Union for Conservation of Nature’s (IUCN) Red List of Threatened Species – was last seen in western Africa in 2006. The IUCN warns that other rhinos could follow saying Africa’s northern white rhino is “teetering on the brink of extinction” while Asia’s Javan rhino is “making its last stand” due to continued poaching and lack of conservation.

“In the case of the western black rhino and the northern white rhino the situation could have had very different results if the suggested conservation measures had been implemented,” Simon Stuart, chair of the IUCN species survival commission said in a statement.


‘Near threatened’

Many plants are also under threat, say the IUCN. Populations of Chinese fir, a conifer which was once widespread throughout China and Vietnam, is being threatened by the expansion of intensive agriculture according to the IUCN.

In the oceans, the IUCN reports that five out of eight tuna species are now “threatened” or “near threatened,” while 26 recently-discovered amphibians have been added to the Red List including the “blessed poison frog” (classified as vulnerable) while the “summers’ poison frog” is endangered.

Do you think these “near threatened” species can still be saved? Is urbanization to blame for this?

Cats Kill Billions Of Animals Each Year

Cats Kill Billions Of Animals Each YearCats are one of the top threats to US wildlife, killing billions of animals each year, a study suggests. The authors estimate they are responsible for the deaths of between 1.4 and 3.7 billion birds and 6.9-20.7 billion mammals annually.

‘Predatory prowess’

Writing in Nature Communications, the scientists said stray and feral cats were the worst offenders. The authors concluded that more animals are dying at the claws of cats in the United States than in road accidents, collisions with buildings or poisonings.

To find out more, researchers from the Smithsonian Conservation Biology Institute (SCBI) and the US Fish and Wildlife Service carried out a review of studies that had previously looked at the predatory prowess of cats.


‘Threat to US wildlife’

Their analysis revealed that the cat killings were much higher than previous studies had suggested: they found that they had killed more than four times as many birds as has been previously estimated. Birds native to the US, such as the American Robin, were most at risk, and mice, shrews, voles, squirrels and rabbits were the mammals most likely to be killed.

Dr Pete Marra from the SCBI said: “Our study suggests that they are the top threat to US wildlife… We hope that the large amount of wildlife mortality indicated by our research convinces some cat owners to keep their cats indoors and that it alerts policymakers, wildlife managers and scientists to the large magnitude of wildlife mortality caused by cat predation.”

The team said that “un-owned” cats, which they classified as strays, feral cats and farm cats, were killing about three times as many animals as pet cats, but that their owners could do more to limit the impact.
