Lord Howe Island
Why in News?
A long-term 16-year study on the island highlighted devastating records of plastic ingestion among fledgling flesh-footed (sable) shearwaters, drawing global environmental attention.
Geography & Location
- Coordinates & Location: Situated in the Tasman Sea, roughly 600 kilometres east of Port Macquarie, Australia.
- Dimensions: A tiny footprint measuring roughly 11 kilometres long and only 2 kilometres at its widest point.
- Volcanic Origin: Formed by volcanic activity millions of years ago, leaving dramatic magma rock formations visible today.
- The Peaks: The southern landscape is dominated by two towering forested peaks—Mount Gower (875m) and Mount Lidgbird (760m).
- Lord Howe Island Group: Comprises 28 islands and rocks. The most famous satellite structure is Ball's Pyramid, a striking 562-meter-tall volcanic spire located 23 km to the southeast.
Flora, Fauna & Biodiversity
- UNESCO World Heritage Site: Inscribed in 1982 due to its spectacular topography and unique, isolated evolutionary history.
- Endemic Plant Life: Nearly 47% of its vascular plants are found nowhere else on Earth, including the world-famous Kentia Palm, which serves as a major economic export for the island.
- Unique Marine Life: It features the world's southernmost coral reef. Because of converging warm equatorial and cold polar currents, it hosts a unique mix of tropical fish and cold-water algae, including the endemic black-and-white Lord Howe clownfish.
- Rare Wildlife: Home to the Lord Howe Island Phasmid (the world's largest stick insect, once thought extinct) and the flightless Lord Howe Woodhen.
History & Population
- Discovery: Uninhabited by indigenous populations, it was first sighted on February 17, 1788, by British Lieutenant Henry Lidgbird Ball, who named it after Admiral Richard Howe.
- Settlement: It permanently became a provisioning port for the whaling industry in June 1834.
- Human Population: It supports a small, tight-knit permanent population of fewer than 400 residents.
