Only 18 extant natural populations are known in NSW, and five populations are likely to have become extinct since they were first recorded. Remnant populations are now usually restricted to roadsides, travelling stock reserves, cemeteries railway easements and the occasional private landholding. Within NSW, natural populations of Button wrinklewort are formally conserved within Queanbeyan Nature Reserve, Crace Grassland Reserve (part of the Canberra Nature Park) and the Red Hill Section of Canberra Nature Park. As a consequence, Button wrinklewort is listed as endangered under the Threatened Species Conservation Act 1995 (NSW) and as endangered under the Environment Protection and Biodiversity Conservation Act 1999 (Cth). Fauna Golden Sun Moth The Golden Sun Moth Synemon plana is a medium-sized, diurnal moth with a wingspan of between for females and for males. Populations of Golden Sun Moth in NSW are located in the area between Queanbeyan, Gunning, Young and Tumut. Historically the moth's distribution extended from in central NSW through the NSW Southern Tablelands, through to central and western Victoria, to in eastern South Australia. Golden Sun Moth occurs in Natural Temperate Grasslands and grassy Box-Gum Woodlands, where the groundcover is dominated by Wallaby Grasses Austrodanthonia spp. The bare ground in inter-tussock spaces is considered to be an important micro-habitat for the species. Larvae feed exclusively on the roots of wallaby grasses and adult Golden Sun Moths, which do not feed, live for only one to for days. The flight period usually lasts from six to eight weeks during November and December in the Queanbeyan region, and adult moths emerge continuously throughout this period. Males Golden Sun Moths fly only in bright sunshine during the warmest part of the day Female Golden Sun Moth have reduced hind wings and rarely fly, though males are capable of active and prolonged flight. Male Golden Sun Moths will not fly greater than 100m away from areas of suitable habitat, therefore populations separated by more than 200m can be considered effectively isolated. Golden Sun Moth populations which have gone extinct, or vacant patches of suitable habitat, are highly unlikely to be recolonised. The loss and degradation of Natural Temperate Grassland and Box-Gum Woodland (as described above) throughout the original range of Golden Sun Moth has resulted in a significant reduction of suitable habitat. As a consequence, Golden Sun Moth is listed as Endangered under the Threatened Species Conservation Act 1995 (NSW) and as Critically Endangered under the
