Endangered Species Day

What Is Endangered Species Day?

September 7 is Australia's "National Threatened Species Day." On September 7, 1936, the last known thylacine, "Benjamin," died at the Hobart Zoo in Tasmania, and the species became extinct. The day was established in 1996, 60 years later. It is a time to focus on threatened plants, animals, and ecosystems, to think about how to protect them, and to honor the people working to conserve them.

Why September 7 Is Endangered Species Day

The thylacine is a symbolic example of an animal driven to extinction by human activity. Marking the day its last individual died is a call not to let the same thing happen again.

• What was the thylacine? A carnivorous marsupial that lived in Tasmania, also called the "Tasmanian tiger" because of the stripes on its back. Like koalas and kangaroos, it carried its young in a pouch.
• The road to extinction: It once lived widely on the Australian mainland, but competition with humans and the dingoes they brought, along with a drying climate, are thought to have left it only in Tasmania. Because it was said to attack settlers' sheep, bounties were placed on it from 1888 to 1909, and more than 2,000 were reportedly killed.
• Sightings continue: Reports of wild sightings have continued since its extinction, but no firm evidence of survival has ever been found.

What Does "Endangered" Mean?

An endangered species is one that has been assessed as having a high likelihood of going extinct in the future. The International Union for Conservation of Nature (IUCN) assesses the extinction risk of species worldwide and publishes the results as the "Red List," classifying threatened species into the following three categories.

• CR (Critically Endangered): An extremely high risk of extinction in the near future.
• EN (Endangered): A very high risk of extinction.
• VU (Vulnerable): A high risk of extinction.

Why Endangered Species Are Increasing

The growing number of endangered species is closely tied to environmental changes caused by human activity.

• Habitat destruction: Deforestation, urban development, and agricultural expansion.
• Climate change: Rising temperatures and sea levels affecting ecosystems.
• Overhunting and poaching: Population declines due to commercial exploitation and illegal trade.
• Invasive species: Competition with and predation on native species.

Fascinating Facts About Endangered Species Day

• Endangered species in Japan: The Japanese crested ibis, the Iriomote cat, and the Amami rabbit are well-known examples.
• Iconic species worldwide: The giant panda, Sumatran tiger, and koala are among the most recognized.
• Red List updates: The IUCN regularly updates its assessments and communicates the latest status to the world.
• Conservation efforts: Zoos and research institutions carry out breeding and protection programs aimed at reintroducing species to the wild.

Ideas for Reflecting on Endangered Species Day

• Research endangered species close to home and learn about their current situation.
• Check out the activities and donation programs of conservation organizations.
• Adopt eco-friendly habits, such as saving electricity and water and reducing plastic use.
• Visit a zoo or museum to learn from exhibits on conservation efforts.

Small Actions to Protect Small Lives Help Build the Future of Our Planet

Endangered Species Day on September 7 is a time to reflect on the importance of biodiversity. The awareness and actions of each one of us can make a real difference in protecting animals and plants on the brink of extinction.
