新南威尔士’ Aussie Ark wildlife sanctuary announced the seven historic births on social media last week.
野生动物 biologist and conservationist Jeff Corwin has been to Tasmania 20 至 30 times over the years in his career and worked extensively with Tasmanian devils.
Corwin said that the world’s largest surviving marsupial carnivore is the “poster child for imperiled wildlife and extinction.”
“They are incredibly adaptive creatures. They are very resilient animals, incredible predators and really remarkable scavengers. 但, they really were not equipped to take on a number of challenges and really were ill-equipped for things like invasive species – especially dogs. 和, they were not ready for roads and development and disease,” 他说. “所以, the three threats they face significantly: one is an internal threat, which is … a sarcoma that they actually spread virally from one Tasmanian devil to the next.”
Due to these pressures, the devils were pushed to the point of regional extinction.
Tasmania was the devils’ last remaining refuge and a disease called Devil Facial Tumour Disease (DFTD) has ravaged the wild population.
“It’s not all that different to the American California condors. 你懂, the California condor just a few decades ago was reduced to being nearly extinct in the wild. 现在 [有] around 500-plus wild condors, but it’s a highly managed population. It requires a lot of micromanagement to ensure that they survive in the wild,” 他说.
“和, this will likely be the same in Australia … because Australia is the poster child as the Tasmanian devil is the poster child for incredible natural wonder and shocking environmental catastrophe,” the animal expert said, noting that poor environmental management had pushed hundreds of Australian species to the brink of extinction.
一个七月 2020 study released by scientists from several Australian universities said 2.46 billion reptiles, 180 million birds, 143 million mammals and 51 million frogs were harmed in the blazes.
Corwin said conservationists also need to take predators and invasive environmental competitors, and other factors like disease into account.
