Nature Season 7 Episode 9 Nature of Australia: a Portrait of the Island Continent: End of Isolation

Nature of Australia: a Portrait of the Island Continent is a documentary series that takes viewers on a journey through the diverse landscapes and wildlife of Australia. In season 7 episode 9, titled End of Isolation, the focus is on the continent's unique history and how, for millions of years, Australia's isolation from the rest of the world has shaped its flora and fauna.

The episode begins with the discovery of the fossils of a giant wombat-like creature that roamed Australia 40,000 years ago. This extinct animal, along with many others, lived on the continent long before humans arrived. The program explains that Australia became separated from other land masses over 100 million years ago, causing the evolution of unique animal and plant species. However, when humans eventually arrived on the continent, they brought with them new animals that began to outcompete and eliminate many of the native species.

The documentary also explores the importance of fire in Australia's ecosystem. Controlled burns have been used for thousands of years by Aboriginal Australians to manage the landscape and promote the growth of certain plants. The episode explains that this practice has become increasingly important as Australia faces more frequent and severe wildfires due to climate change.

Viewers also learn about the threats facing Australia's wildlife, including habitat loss, climate change, and the introduction of invasive species. The program highlights efforts to protect and preserve endangered species, like the Tasmanian Devil and the Australian Sea Lion, through conservation efforts and breeding programs.

Throughout the episode, stunning footage of Australia's diverse landscapes and wildlife is featured. From the arid outback to the lush rainforests, viewers are taken on a visual journey through the continent's natural wonders. The program also features interviews with experts and scientists who provide insight into the history and ecology of Australia's unique environment.

Overall, Nature of Australia: a Portrait of the Island Continent: End of Isolation is a fascinating exploration of Australia's natural history and the challenges facing its unique wildlife today. Viewers will come away with a new appreciation for the diversity and fragility of this island nation's ecology.
