Island with largest recorded biodiversity in the world is threatened by overfishing
Researchers from Conservation International have found a small island near Timor-Leste with staggering species richness. Atauro Island, home to about 8,000 people sits in the middle of the so-called Coral Triangle, known for its biodiverse marine environments.
Species surveys have shown that this island harbours the highest numbers of species ever recorded in a single environment: 642 species were recorded over ten sites around the island, including many rare and endangered ones.
Yet the integrity of the biodiverse ecosystem is thought to be under threat: with signs of blast fishing, fishing using poison and a lack of large predators, the sites’ biodiversity is endangered. Conservation International recommends immediate action to formally protect the area, with commercial fishing strictly forbidden all around the island. The plan should include zoning of the reef, with some no-take sites and some sites designated for fishing by local people. The organisation also proposes that ecotourism might be set up to help local populations - whose primary income comes from fishing - gain financial benefit from keeping the ecosystem intact.
This region of Oceania comprises Australia, New Zealand, the island of New Guinea, and neighbouring islands in the Pacific Ocean. Its ecozone forms a distinct region with a common geologic and evolutionary history which has resulted in a set of unique types of animals and plants. Due to the reverse seasonality with the US and Europe, much food produce is exported to these countries in the winter from Australia and New Zealand. Except for the lush rainforest of Queensland and the east, much of the Australia is arid and unsuitable for arable agriculture. The country is considered highly vulnerable to climate change and associated impacts including droughts and wildfires.
