“…They also indicated that C. kuchlingi was described from a single specimen of uncertain origin with a long history of captivity and so was treated as a junior synonym of "C. rugosa" (now C. oblonga), citing Georges and Thomson (2006) who had questioned the distinction between C. kuchlingi and C. rugosa, but did not synonymize them. The synonymization by Georges and Thomson (2010) was subsequently followed by us (TTWG 2010) and Kennett et al (2014) in their recent CBFTT species account for C. oblonga (see link under that species). However, the synonymization has recently been challenged by Kuchling (CCB, in review, and in litt.…”

“…Although the latter species has been known as C. rugosa since 1974 and was listed as such in previous editions of this checklist, we now follow the ruling of the ICZN and use the name Chelodina (Macrochelodina) oblonga Gray 1841 for the Northern Snake-necked Turtle, although the name Chelodina (Macrochelodina) rugosa Ogilby 1890 remains an available name in the synonymy of C. oblonga. The decision by the ICZN has also been followed by Kennett et al (2014) in their recently published account on the Northern Snake-necked Turtle in this CBFTT monograph series.…”

“…Feral pigs are a major threat to the species across northern Australia (Freeman, 2010; Freeman et al, 2014). Chelodina rugosa is seasonally harvested by Indigenous communities in northern Australia and New Guinea (Fordham et al, 2004; Kennett et al, 2014), but the offtake is considered to be an order of magnitude lower than losses from feral pig predation (Fordham et al, 2008). The species also exhibits a strong density‐dependent response to population reduction (Fordham et al, 2009), has a low age at maturity, and is therefore considered quite resilient to population fluctuations.…”

“…The northern snake‐neck turtle, Chelodina rugosa , occupies the ephemeral waters of the extensive floodplains of rivers in the wet dry tropics (Kennett et al, 2014). It copes with the seasonal unpredictability of free‐standing water by aestivating in the mud of the billabongs it occupies (Grigg et al, 1986; Kennett & Christian, 1994) and does not typically engage in long‐distance migrations between ephemeral and permanent waters.…”

The Australian freshwater turtle fauna is dominated by species in the family Chelidae. The extant fauna comprises a series of distinct lineages, each of considerable antiquity, relicts of a more extensive and perhaps diverse fauna that existed when wetter climes prevailed. Several phylogenetically distinctive species are restricted to single, often small, drainage basins, which presents challenges for their conservation. Specific threats include water resource development, which alters the magnitude, frequency, and timing of flows and converts lentic to lotic habitat via dams and weirs, fragmentation of habitat, sedimentation, nutrification, and a reduction in the frequency and extent of floodplain flooding. Drainage of wetlands and altered land use are of particular concern for some species that are now very restricted in range and critically endangered. The introduced European red fox is a devastatingly efficient predator of turtle nests and can have a major impact on recruitment. In the north, species such as the northern snake‐necked turtle are heavily depredated by feral pigs. Other invasive animals and aquatic weeds dramatically alter freshwater habitats, with consequential impacts on freshwater turtles. Novel pathogens such as viruses have brought at least one species to the brink of extinction. Species that routinely migrate across land are impacted by structural simplification of habitat, reduction in availability of terrestrial refugia, fencing (including conservation fencing), and in some areas, by high levels of road mortality. We report on the listing process and challenges for listing freshwater turtles under the Australian Environment Protection and Biodiversity Conservation Act, summarize the state of knowledge relevant to listing decisions, identify the key threatening processes impacting turtles, and identify key knowledge gaps that impede the setting of priorities. We also focus on how to best incorporate First Nations Knowledge into decisions on listing and discuss opportunities to engage Indigenous communities in on‐ground work to achieve conservation outcomes.

Effective management decisions about the conservation of threatened species often rely on good information about their biology and life-history traits. Nearly half of all turtle species face extinction in the wild through worldwide rapid declines in species abundance and habitat loss. The vulnerable western sawshelled turtle, Myuchelys bellii, from eastern Australia is one such species under threat and for which fundamental information is lacking. The three known populations of M. bellii in the Murray–Darling Basin from the Namoi, Gwydir and Border Rivers catchments were studied over a period of nearly eight years. From capture–mark–recapture data, we studied M. bellii’s sexual maturity and reproduction, compared age of individuals using growth rates derived from annuli and growth increment data and calculated a population estimate for the Queensland population. For the first time this study has quantified the life-history traits of M. bellii including having delayed age at first breeding, with males taking nearly 10 years to mature and females approaching 20 years (from growth increment data), low reproductive effort (14.3 eggs per adult female; 78% of females breeding in any one year) and high survivorship with a predicted lifespan of over 40 years. Of particular management concern for M. bellii is the long-term conservation of the small isolated Queensland population (<400 individuals). The extensive dataset provides a baseline for future investigations and management actions required to improve the conservation outcomes for this threatened turtle.
