Aquatic fauna refuges in Marrggaret River and the Cape to Cape region of Australia’s Mediterranean-climatic Southwestern Province Mark G. Allen1,2, Stephen J. Beatty1 and David L. Morgan1* 1. Freshwater Fish Group & Fish Health Unit, Centre for Fish & Fisheries Research, School of Veterinary and Life Sciences, Murdoch University, South St, Murdoch 6150, Western Austrralia 2. Current address: Department of Aquattic Zoology, Western Australian Museum, Locked Bag 49, Welshpool DC, Perth, Western Australia, 6986, Australia * correspondence to [email protected] SUUMMARY Margaret River and the Cape to Cape region in the extreme south-western tip of Australia are located between Capee Naturaliste in the north and Cape Leeuwin in the south and encompass all intervening catchments that drain westward to the In- dian Ocean. The region has a Mediteerranean climate and houses 13 native, obligate freshwater macrofauna species (i.e. fishes, decapod crustaceans and a bivalve mol- lusc), four of which are listed as threatened under State and/or Commonwealth leg- islation. The most imperiled species are the Margaret River Burrowing Crayfish (Engaewa pseudoreducta) and Hairy Marron (Cherax tenuimanus), both of which are endemic to the Margaret River catchment and listed as critically endangered (also by the IUCN), and Balston’s Pygmy Perch (Nannatherina balstoni) which is vulner- able. The region also houses several fishes that may represent neew, endemic taxa based on preliminary molecular evidence. Freshwater ecosystems in the region face numerous threats including global climate change, a growing huuman population, introduced species, destructive land uses, riparian degradation, waater abstraction, declinning environmental flows, instream barriers, and fire. -

FOREWORD Recovery Plans are developed within the framework laid down in Department of Conservation and Land Management (CALM) Policy Statements No 44 and 50. Recovery Plans outline the recovery actions that are required to address those threatening processes most affecting the ongoing survival of threatened taxa or ecological communities, and begin the recovery process. Recovery Plans delineate, justify and schedule management actions necessary to support the recovery of threatened species and ecological communities. The attainment of objectives and the provision of funds necessary to implement actions are subject to budgetary and other constraints affecting the parties involved, as well as the need to address other priorities. Recovery Plans do not necessarily represent the views or the official position of individuals or organisations represented on the Recovery Team. This Recovery Plan was approved by the Department of Environment and Conservation, Western Australia. Approved Recovery Plans are subject to modification as dictated by new findings, changes in status of the taxon or ecological community and the completion of recovery actions. -
Wellington National Park, Westralia Conservation Park and Wellington Discovery Forest
WELLINGTON NATIONAL PARK, WESTRALIA CONSERVATION PARK AND WELLINGTON DISCOVERY FOREST Management Plan 2008 Department of Environment and Conservation Conservation Commission of Western Australia VISION Over the life of the plan, a balance will exist between the conservation of the planning areas’ natural values and the public demand for recreation and water supply. The area will make an important contribution to reservation of the Jarrah Forest, where natural values, such as granite outcrops, mature growth forest, ecosystems of the Collie River, and our knowledge of them, will be maintained and enhanced for future generations. Visitors to the area will enjoy a range of sustainable recreation opportunities in a variety of forest settings, and provide a benefit to the regional economy. The community will regard the area as a natural asset and will have a greater understanding of its values, and support for their management, through the Wellington Discovery Forest and other education and interpretive facilities. The ancient landscape of the Collie River valley will be recognised as a forest environment of great visual aesthetic appeal, and for its rich Aboriginal heritage, which will be kept alive through the active and ongoing involvement of local Aboriginal people. ii PREFACE The Department of Environment and Conservation (the Department) manages reserves vested in the Conservation Commission of Western Australia (Conservation Commission) and prepares management plans on their behalf. The Conservation Commission issues draft management plans for public comment and provides proposed (final) management plans for approval by the Minister for the Environment. The Conservation and Land Management Act 1984 (the ‘CALM Act’) specifies that management plans must contain: a) a statement of policies and guidelines proposed to be followed; and b) a summary of operations proposed to be undertaken. -

Invasion by the Exotic Crayfish, Cherax Destructor Clark (Parastacidae), Into Habitats of Local Crayfish Near Perth, Western Australia
Invasion by the exotic crayfish, Cherax destructor Clark (Parastacidae), into habitats of local crayfish near Perth, Western Australia. LYNAS, J., STOREY, A., ARMSTRONG, K., PRINCE, J. & KNOTT, B. School of Animal Biology (M092), The University of Western Australia, 35 Stirling Highway, Crawley, Western Australia 6009. AUSTRALIA. ABSTRACT The yabby, Cherax destructor Clark, was introduced into Western Australia in 1932, when ten yabbies were translocated from Victoria to a farm dam near Narembeen. Following subsequent dispersal, this crayfish now co- occurs with two local species C. quinquecarinatus and C. cainii in river systems in the environs of Perth. Congeneric crayfish may persist in sympatry through microhabitat separation. To elucidate the means for co- existance, microhabitat characteristics of the three species were measured in the Canning River system near Perth. Yabbies were associated with sediments having higher clay content than marron; gilgies occurred in river reaches having higher flow than marron. The distribution of the crayfish within this system displayed a mosaic pattern of sympatric distributions, which would allow for competitive interactions between these species. To investigate one aspect of interactions between the introduced yabby and local crayfish species, laboratory-based sediment competition experiments were performed. Similar-sized yabbies displaced both marron and gilgies from preferred substrates. Superior competitive ability under laboratory conditions was manifested through interference, with yabbies preventing local crayfish species from procuring a limiting resource. This study indicates the potential for the introduced yabby to displace local crayfish species. Keywords: introduced crayfish, microhabitat separation, competitive exclusion INTRODUCTION The parastacid freshwater crayfish of the Canning River system, Perth, Western Australia, constitute a fauna of composite origins. -

(February 2019). 1 Native Range and Status in the United States Native Range From CABI (2019): “C. destructor ranges over 2 million km2 in its native range from South Australia and the southern parts of the Northern Territory in the west, to the Great Dividing Range in the east (Riek, 1967; Sokol, 1988).” 1 “It appears that yabbies were largely restricted to lower altitude habitats in inland areas of southeastern Australia including the Murray-Darling Basin before European settlement, with the Euastacus spp. found in higher altitude habitats and the coastal river systems.” Status in the United States No records of Cherax destructor in the wild in the United States were found. From CABI (2019): “[…] the specimens [Cherax destructor] came from a crayfish farm in California (USA) […]” From USFWS (2016a): “The yabby was officially listed as an injurious wildlife species by the U.S. Fish and Wildlife Service in 2016 under the Lacey Act (18.U.S.C.42). Importation and shipping between the continental United States and the District of Columbia, the Commonwealth of Puerto Rico, or any territory or possession of the United States is prohibited.” From USFWS (2016b): “Of the 11 species, four species (crucian carp, Nile perch, wels catfish, and yabby) have been imported in only small numbers since 2011 […]” The Florida Fish and Wildlife Conservation Commission has listed the crayfish, Cherax destructor as a prohibited species. -
The Distribution and Habitat Association of Native And
The distribution and habitat association of native and introduced crayfish in urban wetlands. by Holly Emery-Butcher Bachelor of Science Honours in Environmental Science Murdoch University School of Veterinary and Life Sciences October, 2016 I declare this thesis is my own account of my research and contains as its main content work which has not been previously submitted for a degree at any tertiary education institution. (Holly Emery-Butcher) Abstract As urbanisation puts increasing pressure on biodiversity, there is growing need to conserve biodiversity outside of protected areas. Anthropogenic wetlands (i.e. human created) may offer a way to do this by providing habitat for species such as crayfish. As the distribution and habitat association of freshwater crayfish in Swan Coastal Plain wetlands is largely unknown, the aims of this study were: to identify the habitat characteristics associated with the presence and absence of introduced (Cherax destructor) and native (Cherax quinquecarinatus) freshwater crayfish in the Beeliar and Jandakot wetlands on the Swan Coastal Plain; to compare the distribution and habitat use of introduced C. destructor and native C. quinquecarinatus between natural and anthropogenic urban wetlands. Fifty-three wetlands were sampled for crayfish using baited box traps and sweep nets between May and September 2016. Habitat characteristics were documented using rapid assessment and water quality variables recorded. Log-linear modelling and ANOSIM were then used to examine the association between crayfish and habitat characteristics. Crayfish distribution was much more limited than expected, and they were absent from 29 (55%) wetlands. Unfortunately, C. quinquecarinatus were not found in large enough numbers to model alone, so the data from this species was pooled with that of other native crayfish. -
Fish and Freshwater Crayfish Communities of the Brunswick and Preston Rivers
Fish and freshwater crayfish communities of the Brunswick and Preston Rivers Prepared for the Leschenault Catchment Council March 2006 D Morgan & S Beatty Freshwater Fish Research Acknowledgements The authors would like to thank Leigh Taylor (Leschenault Catchment Council) and Cassandra Jury (Cape to Cape Catchments Group) for initiating the study and coordinating sample sites. We would also like to thank the South West Catchment Council for funding the project. Brief This report details the findings of the survey conducted by Freshwater Fish Research in February 2006 of the fish and freshwater crayfish fauna of the Brunswick and Preston Rivers that was commissioned by the Leschenault Catchment Council (LCC). The results of this study will be used by the LCC in preparing River Action Plans for these two systems. Report should be cited as: Morgan, D. & Beatty, S. (2006). Fish and freshwater crayfish communities of the Brunswick and Preston Rivers. Freshwater Fish Research, Murdoch University report to the Leschenault Catchment Council. 1 Fishes of the Brunswick & Preston Rivers Background The Leschenault Inlet, located on the Swan Coastal Plain near Bunbury, is the estuary of the Brunswick, Collie, Preston and Ferguson Rivers. There is a considerable amount of information detailing the fish fauna of the Leschenault Inlet with Potter et al. (1997, 2000) recording 42 species of fish from 26 families. The estuary is dominated by gobies, atherinids and clupeids which comprised almost 90% of the fishes. Potter et al. (2000) also reported 13 species from gill net captures in the lower (tidal) Collie River. Neither of these studies reported on the fishes found within the freshwaters of the Leschenault Inlet catchment and although Pen & Potter (1990, 1991a, b, c, d, 1992) conducted biological studies on a number of native and introduced freshwater fishes in the upper Collie River by, there is no published information regarding the prevailing fishes (or freshwater crayfishes) of the Brunswick or Preston Rivers. -

Discussion Paper
DEPARTMENT OF FISHERIES DISCUSSION PAPER THE TRANSLOCATION OF BROWN TROUT (Salmo trutta) AND RAINBOW TROUT (Oncorhynchus mykiss) INTO AND WITHIN WESTERN AUSTRALIA June 2002 FISHERIES MANAGEMENT PAPER No. 156 Fisheries Management Paper No 156 OPPORTUNITY FOR PUBLIC COMMENT This discussion paper has been prepared to assist in the assessment of the possible impact of the translocation of brown trout (Salmo trutta) and rainbow trout (Oncorhynchus mykiss), into and within Western Australia, for the purposes of recreational stock enhancement in public waters, non-commercial aquaculture on private properties and commercial aquaculture. In assessing the translocation of any aquatic species, economic and social benefits must be balanced with biological and environmental risks. Comments about this discussion paper are sought from all stakeholders, including industry members, existing and potential trout farmers, relevant community interest groups, government agencies and interested members of the public. In particular, the Department of Fisheries would appreciate your suggestions for the following: • River catchments and drainage basins with high conservation value where trout stocking and aquaculture should be managed or prohibited, identifying the benefits of additional management or prohibitions. • River catchments and drainage basins where trout stocking and aquaculture should be permitted and encouraged, and may already be taking place. This discussion paper and your comments will be used to develop a draft policy on the translocation of brown -
