As the East Australian Current pushes warmer waters down Australia's eastern coast, kelp forests off New South Wales and Tasmania have seen dramatic losses and Victorian forests … As a result, kelp are crucial to the ecological, social, and economic well-being of coastal communities. Over the succeeding decade, those patches coalesced so that by the late 1990s more than 50% of the rocky shores of New South Wales Australia were sea urchin barrens ( Andrew and O’Neill, 2000 ). The giant kelp marine forest of south east Australia is among 85 threatened ecological communities listed under the EPBC Act. The loss is so stunning because this was a place where kelp forests were once so dense that they merited mention on nautical charts. Warming waters have also boosted populations of predatory urchins, which gnaw on kelp roots and compound the loss. So called because of their resemblance to forests on land both in structure and the life they support, kelp are part of the phaeophyceae family – the brown seaweeds. Kelp forests along some 100km of Western Australia’s coast have been wiped out, and many more areas damaged, by a marine heatwave that struck the area in … A hundred kilometres of kelp forests off the western coast of Australia were wiped out by a marine heatwave between 2010 and 2013, a new study has revealed. The ‘Great Southern Reef’: social, ecological and economic value of Australia’s neglected kelp forests Scott Bennett A B I, Thomas Wernberg A, Sean D. Connell C D, Alistair J. Hobday E, Craig R. Johnson F and Elvira S. Poloczanska G H + Author Affiliations - Author Affiliations. Kelp forests off the West Sussex coast are among the most biodiverse environments on the planet, but they have been damaged by changing fishing … The “chronic” warming has wiped out 95 per cent of giant kelp forests, pushed fisheries to the brink, diseased much of the state’s oyster stocks, and heralded the arrival of new, invasive species. Protecting Australia’s Kelp Forests and its other Great Reef Destination , Discovery , Australia Singapore-Hong Kong travel bubble to start on 22 November The Australian island state has lost more than 95 percent its kelp forests in recent decades. Rising sea temperatures have already wiped out 100 kilometres of kelp forest along the south coast of Western Australia – and this unprecedented loss looks set to worsen. He, and others, blame climate change and, more specifically, warmer, nutrient-poor waters travelling down the East Australian Current into Tassie’s cold-water environment. Kelp forests have declined in Western Australia, South Australia, Tasmania and New South Wales. kelp forest: translation /ˈkɛlp fɒrəst/ (say 'kelp foruhst) noun an underwater stand of high-growing kelp, as the giant kelp; found mostly in temperate and arctic waters, including waters along the coast of the southern Australian mainland and Tasmania. In Western Australia kelp forests were wiped out during an extreme marine heatwave, which was probably a consequence of climate … Unfortunately, Australia’s kelp forests feature heavily among the declining populations. The causes of this loss are diverse, but share a common factor: people. Project researcher and Climate Foundation Postdoctoral Fellow Dr Cayne Layton, said that in 2012 southeastern Australia’s giant kelp forests were listed by the Australian Government as an endangered marine community, the first such listing for a marine community in Australia. Our island is surrounded by them, as are the temperate waters stretching from Portugal to Russia and from Ecuador to Southern Australia and New Zealand. Kelp forests. Dr. Tom Bell is a postdoc scientists and the University of California in LA and the University of Alaska Southeast researching how kelp responds to its environment. Related Topics Abalone Kelp are large brown algae that live in cool, relatively shallow waters close to the shore. Australian Kelp Restoration Network. Kelp is as important to the sea as forests are to land, said Layton, “so if you can imagine what the world would be like without trees, that’s what a world without kelp forests would be like”. Kelp forests can be seen along much of the west coast of North America. A 10-week surge in ocean temperatures off the Western Australian coast has killed off large patches of kelp forest, the "biological engine" of Australia's southern reefs. Kelp, a type of seaweed known for creating spectacular underwater forests, dominates Australia's Great Southern Reef. Kelp forests define >8000km of temperate coastline across southern Australia, where ~70% of Australians live, work and recreate. “Kelp forests are not only the foundation of the food chain in these ecosystems, but physically they create the habitat, they create that complexity,” Cayne Layton says. About 90% of the forests … kelp forest. Kelp forests off south Australia of the late 1980s were described as patches of CCA-dominated barrens created by Centrostephanus rodgersii within the region’s diverse kelp forests (Andrew, 1993). These underwater towers of kelp provide food and shelter for thousands of fish, invertebrates, and marine mammal species. They are the foundation of the Great Southern Reef, which stretches 8,000 kilometres along Australia’s southern coastline. Bringing together researchers, fishers, government, industry and the community in conserving and restoring kelp forests. [Australia] Marine scientists are planting tiny spores of giant kelp in southern Tasmania to rebuild the state’s famous underwater forests and tackle climate change. Kelp forests also support coastal food-webs and valuable fisheries and provide a suite of additional ecosystem services. Healthy kelp (left) in Western Australia is an important part of the food chain but it is vulnerable to even small changes in temperature and particularly … Help the kelp. The prime threats to the kelp forests, noted in the Scientific Committee’s (SC) Advice to the Minister, are a climate-change-driven increase in sea surface temperature, associated with the southward extension of the East Australian Current (EAC), and a corresponding expansion in the range of kelp-grazing sea urchins. Much like terrestrial forests, these marine forests create complex habitat for diverse communities of flora and fauna. Kelp forests dominate the rocky coasts of temperate Australia and are the foundation of the Great Southern Reef. Listed as an endangered ecological community by the Australian government in 2012, Tasmania’s giant kelp forests are more than 95% gone, with a … Much like terrestrial forests, these marine forests create complex habitat for diverse communities of flora and fauna. Baron, who owns Eaglehawk Dive Centre, has been exploring these waters for 50 years – but the environment he knew as a boy is vastly different to the one he knows now. The progression of the destruction of a kelp forest in Tasmania by urchins, from left to right. The last remaining kelp forests exist only south of Bruny Island, Mr Baron says. Despite this, public and political awareness of the scale and significance of this marine ecosystem is low, and research investment miniscule (<10%), relative to comparable ecosystems. They grow in dense groupings much like a forest on land. The cooler water kelp forests support a significant component of Australia’s fisheries and is estimated to be worth over $10bn to the Australian economy. Kelp forests are highly productive foundation species along much of the world’s coastline. Distribution. The Australian government now lists giant kelp forests as an endangered ecological community. An ecological community is a group of species that co-exist in a specific type of habitat and interact with each other. Crawley, WA, Australia Kelp forests dominate the rocky coasts of temperate Australia and are the foundation of the Great Southern Reef. For example, the intensification of the warm East Australian Current has been linked to the disappearance of 95% of Giant Kelp forests in Tasmania (Australia). Kelp forests dominate the rocky reefs of temperate Australia, where they can grow up to 40 metres tall. The kelp demise “The forest was the canary in the mine – an indicator that something was wrong,” says Mick, who has been banging on about the kelp’s demise for years. In 2012, giant kelp forests were listed as an endangered ecological community by Australia’s government, the first marine community to be considered as such. The loss has been so stark that the Australian government listed Tasmania’s giant kelp forests as an “endangered ecological community“— the first time the country has given protection to an entire ecological community. Kelp has one of the fastest growth rates of any of the marine plants (up to 60cm per day or 3kg of dry weight per square metre of habitat per day recorded for the Giant Kelp). But recent heat waves have devastated these kelp forests and may be … Jorge Assis is researching species distributions in kelp forests and what environmental drivers affect these forests. Kelps are important contributors to some Antarctic bottom communities, but it is in sub-Antarctic latitudes that they dominate. These giant algae need to be bathed in cool, nutrient-rich currents in order to thrive, yet regional warming in recent decades has extended the waters of the warmer East Australian Current into Tasmanian seas to devastating effect, wiping out kelp forests one by one. Kelp forests also support coastal food-webs and valuable fisheries and provide a suite of additional ecosystem services. Shutterstock What’s an ecological community anyway? “[In the media] it’s all about the tropical coral reefs, but temperate reefs are actually equally important and bio-diverse,” he says.
