Functionally Extinct Animals 2019

In the aftermath of 2019s scorching brushfires in Australia images of singed Koalas struggling among the remnants have captured the worlds attention.

Functionally extinct animals 2019. It is threatened in some parts of its range and not in others says Diana Fisher associate professor in the school of biological sciences at the University of Queensland. For instance American chestnut trees were once widespread throughout North America but a fungus killed 35 billion of them in the early 20th century. The headlines claiming that koalas are functionally extinct appear to be based on a claim from a koala conservation group earlier in 2019.

Recent bushfires along with prolonged drought and deforestation has led to koalas becoming functionally extinct according to experts. The species is likely extinct said David Sischo the snail extinction prevention program coordinator at the Hawaii Department of Land and Natural Resources.

But ecologist Diana Fisher says the fires damaged only 1 million hectares of the 100 million hectares of forest in eastern Australia and that koalas are still nowhere near functionally extinct. Which they claim is to better reflect the content of the reporting. Says Koalas are functionally extinct as bushfires in Australia continue to destroy their habitat.
