Description: The Darling River Snail (also known as ‘River Snail’) is a medium-sized (20-25 mm) freshwater snail that was once common and widespread in the Darling River and its tributaries. However populations declined rapidly over the last few decades, probably as a result of weir building and other activities associated with river flow management. They are now virtually extinct throughout their natural range. In the last decade, living specimens have only been found from within irrigation pipelines in southern NSW.

River Style®planform and substratum categories were then assigned to each Geofabric segment.MaxEnt 3.3.3 is a widely used species distribution modelling program that utilises presence records to generate probabilities of occurrence based on a suite of environmental variables quantified across the area of interest. It was used to model the current geographic distribution of each listed threatened freshwater aquatic species or population. We utilised logistic output to plot the predicted distribution of each species. This output equates to a probability that the species will be observed in each river reach, given the environmental conditions that exist there relative to the environmental conditions where the species is known to occur. For this mapping, above 33% probability was considered predicted presence. In addition, predicted separate populations were connected by manual interpretation. The predicted values for each river reach were converted from the Geofabric framework to the higher resolution 2013 NSW Strahler Stream Order Hydroline.

Description: Craterocephalus fluviatilisis a small freshwater fish, native to the floodplains of the southern MurrayDarling Basin. They were once widespread and abundant throughout their range; however the species has suffered a serious decline in abundance and distribution, and are now considered one of the most threatened vertebrate species in Australia. Murray Hardyhead is rare in NSW and only a few isolated populations occur in Victoria and South Australia. All populations are threatened by declining water levels, habitat loss and impacts of pest fish (including Gambusia, Redfin and Carp).It is listed as a ‘critically endangered’ species in NSW under the Fisheries Management Act 1994.https://www.dpi.nsw.gov.au/fishing/species-protection/what-current/critically-endangered-species/murray-hardyhead.This indicative distribution was derived from survey records and expert opinion.
Description: Oxleyan pygmy perch ( Nannoperca oxleyana) are a small freshwater fish endemic to the coastal region of eastern Australia, from northern NSW to south-eastern Queensland. They have specific habitat requirements and are patchily distributed within this range.They are an endangered species - http://www.dpi.nsw.gov.au/fishing/species-protection/conservation/what-current/endangered-species/oxleyan-pygmy-perch/oxleyan-pygmy-perch. The methods used to create the predicted current distribution of Oxleyan Pygmy Perch are as follows. As the species occur in wetlands, the method described fully in: NSW Department of Primary Industries (2015), NSW Fish Community Status 2015 – Final Report, did not map all potential habitat. In addition to this modelling, records and previous critical habitat mapping (2007) were used. Critical habitat stream lines were identified from the 2012 NSW Topographic Hydro Line. Wetland boundaries were delineated from SEPP (Dec 2016 version).
