NASA Satellite Sees Blake's Remnants Bringing Desert Rain to Western Australia 10 January 2020, by Rob Gutro NASA satellite sees Blake's remnants bringing desert rain to Western Australia 10 January 2020, by Rob Gutro southeastern corner of the region. The Australian Government Bureau of Meteorology (ABM) in Western Australia issued several flood warnings at 10:47 a.m. WST on Friday Jan. 10. Flood Warnings were in effect for four areas. There is a Major Flood Warning for the De Grey River Catchment and a Flood Warning for the Fortescue River, Salt Lakes District Rivers, and southwestern parts the Sandy Desert Catchment. ABM said, "Major flooding is occurring in the Nullagine River in the De Grey river catchment.

  • Introduction of an Alien Fish Species in the Pilbara Region of Western
    RECORDS OF THE WESTERN AUSTRALIAN MUSEUM 33 108–114 (2018) DOI: 10.18195/issn.0312-3162.33(1).2018.108-114 Introduction of an alien fsh species in the Pilbara region of Western Australia Dean C. Thorburn1, James J. Keleher1 and Simon G. Longbottom1 1 Indo-Pacifc Environmental, PO Box 191, Duncraig East, Western Australia 6023, Australia. * Corresponding author: [email protected] ABSTRACT – Until recently rivers of the Pilbara region of north Western Australia were considered to be free of introduced fsh species. However, a survey of aquatic fauna of the Fortescue River conducted in March 2017 resulted in the capture of 19 Poecilia latipinna (Sailfn Molly) throughout a 25 km section of the upper catchment. This represented the frst record of an alien fsh species in the Pilbara region and the most northern record in Western Australia. Based on the size of the individuals captured, the distribution over which they were recorded and the fact that the largest female was mature, P. latipinna appeared to be breeding. While P. latipinna was unlikely to physically threaten native fsh species in the upper reaches of the Fortescue River, potential spatial and dietary competition may exist if it reaches downstream waters where native fsh diversity is higher and dietary overlap is likely. As P. latipinna has the potential to affect macroinvertebrate communities, some risk may also exist to the macroinvertebrate community of the Fortescue Marsh, which is located immediately downstream, and which is valued for its numerous short range endemic aquatic invertebrates. The current fnding indicated that despite the relative isolation of the river and presence of a low human population, this remoteness does not mean the river is safe from the potential impact of species introductions.

Port Hedland AREA PLANNING STUDY Foreword Port Hedland is one of the Pilbara’s most historic and colourful towns. The townsite as we know it was established by European settlers in 1896 as a service centre for the pastoral, goldmining and pearling industries, although the area has been home to Aboriginal people for many thousands of years. In the 1960s Port Hedland experienced a major growth period, as a direct result of the emerging iron ore industry.

    DOI: 10.18195/issn.0313-122x.78(2).2015.485-513 Records of the Western Australian Museum, Supplement 78: 485–513 (2015). The riparian fl ora and plant communities of the Pilbara region of Western Australia M.N. Lyons Department of Parks and Wildlife, Science and Conservation Division, Kieran McNamara Conservation Science Centre, Locked Bag 104, Bentley Delivery Centre, Western Australia 6983, Australia. Email: [email protected] Abstract – A survey of riparian fl ora and plant communities was undertaken at 98 wetlands and rivers in the Pilbara region of Western Australia. Sampling was quadrat-based, with fl oristics, surface soils and wetland attributes recorded. Selected sites captured the full range of Pilbara wetland types including springs, river pools, claypans, salt marshes and rock pools. A total of 455 taxa was recorded from the survey sites, representing ca. 25% of the known fl ora of the Pilbara bioregion. The fl ora is dominated by taxa with Eremaean and tropical affi nities, with only six taxa endemic in the region. Of recorded taxa known from four or fewer bioregions, most are shared with the adjacent Carnarvon and Gascoyne bioregions rather than the adjoining internally draining deserts. Sixteen taxa of conservation signifi cance were documented, with claypans, the Fortescue Marsh, and Millstream and Karijini National Park sites dominating occurrences of rare species. Eight major groups were defi ned by classifying wetlands in terms of species presence/absence data. Floristic patterning was strongly aligned with the major wetland types (geomorphic/hydrological) used in the primary sampling stratifi cation. A combination of wetland morphology/hydrological setting, site edaphic attributes and distance to the coast were dominant variables related to riparian fl oristic composition.

  • Groundwater Resource Assessment and Conceptualization in the Pilbara Region, Western Australia
    Earth Systems and Environment https://doi.org/10.1007/s41748-018-0051-0 ORIGINAL ARTICLE Groundwater Resource Assessment and Conceptualization in the Pilbara Region, Western Australia Rodrigo Rojas1 · Philip Commander2 · Don McFarlane3,4 · Riasat Ali5 · Warrick Dawes3 · Olga Barron3 · Geof Hodgson3 · Steve Charles3 Received: 25 January 2018 / Accepted: 8 May 2018 © Springer International Publishing AG, part of Springer Nature 2018 Abstract The Pilbara region is one of the most important mining hubs in Australia. It is also a region characterised by an extreme climate, featuring environmental assets of national signifcance, and considered a valued land by indigenous people. Given the arid conditions, surface water is scarce, shows large variability, and is an unreliable source of water for drinking and industrial/mining purposes. In such conditions, groundwater has become a strategic resource in the Pilbara region. To date, however, an integrated regional characterization and conceptualization of the occurrence of groundwater resources in this region were missing. This article addresses this gap by integrating disperse knowledge, collating available data on aquifer properties, by reviewing groundwater systems (aquifer types) present in the region and identifying their potential, and propos- ing conceptualizations for the occurrence and functioning of the groundwater systems identifed. Results show that aquifers across the Pilbara Region vary substantially and can be classifed in seven main types: coastal alluvial systems, concealed channel

  • The Importance of Western Australia's Waterways
    The Importance of Western Australia's Waterways There are 208 major waterways in Western Australia with a combined length of more than 25000 km. Forty-eight have been identified as 'wild rivers' due to their near pristine condition. Waterways and their fringing vegetation have important ecological, economic and cultural values. They provide habitat for birds, frogs, reptiles, native fish and macroinvertebrates and form important wildlife corridors between patches of remnant bush. Estuaries, where river and ocean waters mix, connect the land to the sea and have their own unique array of aquatic and terrestrial flora and fauna. Waterways, and water, have important spiritual and cultural significance for Aboriginal people. Many waterbodies such as rivers, soaks, springs, rock holes and billabongs have Aboriginal sites associated with them. Waterways became a focal point for explorers and settlers with many of the State’s towns located near them. Waterways supply us with food and drinking water, irrigation for agriculture and water for aquaculture and horticulture. They are valuable assets for tourism and An impacted south-west river section - salinisation and erosion on the upper Frankland River. Photo are prized recreational areas. S. Neville ECOTONES. Many are internationally recognised and protected for their ecological values, such as breeding grounds and migration stopovers for birds. WA has several Ramsar sites including lakes Gore and Warden on the south coast, the Ord River floodplain in the Kimberley and the Peel Harvey Estuarine system, which is the largest Ramsar site in the south west of WA. Some waterways are protected within national parks for their ecosystem values and beauty.
