Conservationists fear a government plan to double groundwater extraction from the Martuwarra Fitzroy River catchment in Western Australia<\/a> could jeopardise threatened sawfish populations.<\/p>\n

The untamed river, which flows 700km through the Kimberley<\/a> to King Sound, is considered the last stronghold for sawfish globally and is home to four of the world\u2019s five species.<\/p>\n

Sawfish, a type of ray named for their chainsaw-like snouts, are \u201cprobably one of the most unique looking animals on the planet,\u201d said Dr Leonardo Guida, from the Australian Marine Conservation Society. The river, its estuary, and near-shore marine environment are home to largetooth, dwarf, green and narrow sawfish, all protected under national environment laws.<\/p>\n

Endangered largetooth sawfish \u2013 the largest and most imperilled \u2013 are born at the river\u2019s mouth. The young spend several years inhabiting the river, its tributaries and deep aquifer-fed pools, before heading out to sea. Adults can reach up to seven metres in size.<\/p>\n

\u201cWhat makes the Fitzroy rRiver incredibly special and unique from a sawfish perspective is that it is the baseline, not just in Australia, but globally of what a relatively untouched sawfish population looks like,\u201d Guida said.<\/p>\n

But a state government proposal to increase the groundwater allocation from about 32GL<\/a> to 75.7GL has raised concern among environmentalists and communities. Groundwater aquifers supply several large pools and wetlands that act as crucial refuges for sawfish and other species during long dry periods.<\/p>\n

\u201cThe underground water stores that feed these refuge pools are absolutely critical in a landscape that\u2019s so hot and dry,\u201d said Martin Pritchard from Environs Kimberley, which works to protect nature in the region.<\/p>\n

\u201cSawfish won\u2019t survive without these pools, which also provide life support for barramundi, a whole range of other fish, freshwater prawns, and big trees and vegetation that sustain birds, possums, bats and insects.<\/p>\n

\u201cWe\u2019re really concerned that the current proposal by the government is way too much and could cause significant damage to the river and the groundwater-dependent ecosystems.\u201d<\/p>\n

The WA government\u2019s draft water plan, now out for consultation<\/a>, has proposed no additional surface water allocations and no dams on the river. Environs Kimberley supported these aspects of the plan, but called for a more precautionary approach to groundwater.<\/p>\n

Dr Anne Poelina, executive chair of the Martuwarra Fitzroy River Council, an alliance of elders and young leaders from traditional owners of the catchment, said the lived experience of Aboriginal people on country was that the river was already stressed. \u201cWater is precious, it\u2019s a life force, and if living water systems continue to decline it will continue to affect people\u2019s lives and livelihoods as well as the environment, including access to clean drinking water and the rising cost-of living,\u201d the Nyikina Warrwa woman said.<\/p>\n

Poelina said there were currently too many unknowns \u2013 about the connectivity of the system and about how much groundwater there was, and the potential impact of sea level rise \u2013 to start allocating groundwater for profit-making activities.<\/p>\n

Both communities andthe WA department of water and environmental regulation (DWER) needed a longer timeframe to be able gather information before the plan was finalised, or any additional licences given, she said.<\/p>\n

A similar water allocation plan in the Pilbara had failed, with groundwater aquifers<\/a> in the region in decline, which didn\u2019t offer much confidence about the plan for the Kimberley.<\/p>\n

\u201cThese are human issues as well as environmental issues \u2013 it does not make us confident when the science and lived experience stories of how these systems are changing right now. These are public interest matters. This is going to impact everyone that\u2019s living within this system, we need to proceed with caution and not take risks, with the lives of all Kimberley people and our environment,\u201d Poelina said.<\/p>\n

Farmers have sought greater access to the river\u2019s surface and groundwater for agriculture and livestock, in various plans dating back to the 1950s<\/a>. Recent proposals for unconventional gas developments<\/a>, known as fracking, could also have implications for groundwater resources.<\/p>\n

Dr Ryan Vogwill, a hydrogeologist said groundwater played an \u201cincredibly important\u201d role supporting the high biodiversity and cultural values of the river ecosystem during dry periods.<\/p>\n

\u201cIn a big wet season, the whole system floods with water and goes all the way to the coast,\u201d he said. \u201cBut in smaller years, when there\u2019s not so much rainfall, the river may only flow a little, or may not flow at all.<\/p>\n

\u201cIn those periods when the surface water isn\u2019t flowing and hasn\u2019t flowed for some time, groundwater becomes key to the environment persisting and staying healthy.\u201d<\/p>\n

Vogwill said interactions between the surface water and different layers of groundwater aquifers were highly complex and more monitoring would help to better understand the system and assess any potential risks \u2013 whether from increased use for pastoral industries, or proposals for unconventional gas<\/a>.<\/p>\n

Applicants seeking a licence would need to demonstrate \u201csustainable groundwater use\u201d and \u201cprotect water-dependent ecosystems and sites of ecological, cultural and social significance,\u201d according to the draft plan.<\/p>\n

Guardian Australia asked DWER how the groundwater allocation was determined and whether the government would invest in additional monitoring but did not receive a response.<\/p>\n","protected":false},"excerpt":{"rendered":"Conservationists fear a government plan to double groundwater extraction from the Martuwarra Fitzroy River catchment in Western Australia…\n","protected":false},"author":2,"featured_media":456799,"comment_status":"","ping_status":"","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[22],"tags":[242,85,46,141],"class_list":["post-456798","post","type-post","status-publish","format-standard","has-post-thumbnail","category-environment","tag-environment","tag-il","tag-israel","tag-science"],"_links":{"self":[{"href":"https:\/\/www.newsbeep.com\/il\/wp-json\/wp\/v2\/posts\/456798","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.newsbeep.com\/il\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.newsbeep.com\/il\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/il\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/il\/wp-json\/wp\/v2\/comments?post=456798"}],"version-history":[{"count":0,"href":"https:\/\/www.newsbeep.com\/il\/wp-json\/wp\/v2\/posts\/456798\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/il\/wp-json\/wp\/v2\/media\/456799"}],"wp:attachment":[{"href":"https:\/\/www.newsbeep.com\/il\/wp-json\/wp\/v2\/media?parent=456798"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.newsbeep.com\/il\/wp-json\/wp\/v2\/categories?post=456798"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.newsbeep.com\/il\/wp-json\/wp\/v2\/tags?post=456798"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
