Effective conservation for humpback Whale in Australia

15/09/2015

     Australia has one of the highest rates of animal species that face extinction, decline or negative impacts from human behavior in the world. However, over the last decade, there have been rare occurrences of animals that are rebounding and thriving. One example is the conservation success story of the recovery of the humpback whales that breed in both East and West Australian waters. This new study, published in Marine Policy and led by Dr. Michelle Bejder, reviews data collected in past studies and proposes a revision of the conservation status for the humpback whales found in Australian waters.          In Australia, the east and west coast humpback whale populations are listed as a threatened species with a 'vulnerable' status as defined by the Environment Protection and Biodiversity Conservation Act 1999 (EPBC Act). However, according to Professor Lars Bejder at Murdoch University Australia, School of Veterinary and Life Sciences and his international co-authors, data reveals that these whale populations are increasing at remarkable rates (9% for West Coast and 10% for East Coast; as of 2012), the highest documented worldwide. As of 2012, both the East and West Coast whale populations had more than 63% (East Coast) and 90% (West Coast) of the number of whales estimated in each population before the whaling era (approximately 1912-1972). Since humpback whales no longer fulfil the criteria of the EPBC Act, the study suggests, they should have their conservation status revised.       "Our conclusions serve as an example of optimism and hope in the conservation of marine fauna protection, as the relentless communication of marine conservation problems does not always encourage politicians, policy makers, and the public to solve them," said Prof. Bejder. "We highlight a success story, which provides hope and optimism that ongoing conservation actions can prevail."   Lưu Huyền Trang
