Working scientist profiles

This article is part of an occasional series in which Nature profiles scientists with unusual career histories or outside interests.

Conservationist Anne Poelina has a deep connection to the fresh water that runs through the dry red-rock landscape of the Kimberley region in Western Australia. Poelina identifies as a Nyikina Warrwa woman, and her people are the Traditional Custodians of the Martuwarra Fitzroy River. The river meanders through the region’s arid land, cutting a path of about 735 kilometres long through steep gorges, savannahs and flood plains before terminating at King Sound, a delta fringed by tidal mangroves by the Indian Ocean.

The Martuwarra Fitzroy River is one of Australia’s last-remaining relatively intact, undammed tropical river systems. For now.

The river faces many threats, for instance, from water use in agricultural irrigation. It’s also at risk from proposed plans to extract natural gas through fracking, or hydraulic fracturing, and to look for rare-earth elements and metals such as vanadium and titanium. Moreover, climate change is predicted to cause extreme floods and droughts.

Should we treat rivers as living things?
