Summary  The Mountain Pygmy-possum Burramys parvus has been listed as an endangered species across its range in the alpine and subalpine areas of New South Wales and Victoria. This study reports on the occurrence of the species in an artificial habitat, spoil dumps that were created in the 1950s as a result of the construction of underground tunnels associated with the Snowy Hydro-electric Scheme. Thirty-four B. parvus were captured in 1065 trapnights on spoil dumps in Happy Jacks Creek valley, in northern Kosciuszko National Park in October and November 2011. In January 2012, 22 individuals were captured in 360 trapnights on a spoil dump at Guthega Adit Camp in southern Kosciuszko National Park. Seven radio-collared individuals tracked in Happy Jacks Creek valley resulted in the location of 5 day shelters in spoil dump habitat, including individuals that were originally trapped in nearby natural habitat. This study indicates that there may be opportunity to create further artificial habitat on sites not currently used by this highly restricted species.
