Southward range expansion of the Mourning Gecko Lepidodactylus lugubris on mainland Australia and nearshore islands

The Mourning Gecko Lepidodactylus lugubris is a species that colonises areas of human habitation and its spread is assisted by humans. This note documents southward range expansion of this species down the Queensland coast

Wetland reservation on Victoria\u27s northern plains and riverine forests

The depletion and reservation levels of wetlands varied significantly both across the Murray Fans and Victorian Riverina bioregions and in the study area of the Victorian Environmental Assessments Council\u27s River Red Gum Forests Investigation. The proportion of Freshwater Meadows in protected areas was substantially lower than for other wetland types. Furthermore, of the wetlands that are reserved, many were only partially within a protected area. A variety of reserve categories are used to protect wetlands across the three regions, ranging from reserves with high legal protection and a strong focus on biodiversity conservation to reserves with a lower level of protection and emphasis on biodiversityconservation. The findings highlight that many wetlands are incompletely reserved in Victoria\u27s northern plains and riverine forests. The current review of public land use in the River Red Gum Forests, which includes Barmah Forest, should recognise these issues to ensure the effective reservation of wetland ecosystems.<br /

The diet of a Southern Boobook Ninox novaeseelandiae in Box-ironbark country, central Victoria

The diet of a Southern Boobook Ninox novaeseelandiae in a Box-Ironbark woodland remnant in central Victoria was studied. An analysis of 42.5 pellets found invertebrates to represent 82% of the total prey items, but vertebrates, in the form of the House Mouse Mus domesticus, to represent 88% of the biomass. The proportion of spiders as prey items in the diet in this instance (43%) was significantly higher than in other studies on mainland Australia.<br /

Diet of powerful owls Ninox strenua in inner city Melbourne parks, Victoria

Most dietary studies of Powerful Owls Ninox strenua have been from forested habitats or partially disturbed habitats on the urban fringe. The diets of single Powerful Owls roosting in two inner city parks in Melbourne, Victoria, in 2008 and 2009 were analysed. Common Brushtail Possum Trichosurus vulpecula and Common Ringtail Possum Pseudocheirus peregrinus were the only prey species recorded in the Fitzroy Gardens (occurring in equal numbers in the Owl&rsquo;s diet), whereas Common Brushtail Possums and Black Rats Rattus rattus were recorded in the diet of the Flagstaff Gardens bird. This is a less diverse prey selection than recorded in the only other inner city dietary analysis for this species

Ecological notes on the East Gippsland burrowing crayfish Engaeus orientalis, including burrow structure and associated fauna

Despite Australia having a high diversity of freshwater crayfish species, the ecology of many of these species remains poorly known, particularly burrowing crayfish of the genus Engaeus. Biological information on colour, behaviour, burrow structure, associated burrow fauna and habitat of the East Gippsland Burrowing Crayfish Engaeus orientalis obtained during incidental observations in 2007 and 2008 is provided. The burrow structure took the form of radiating runways under a rock slab, while the burrow location was in a semi-disturbed site away from water. Both are atypical for this species

Diet of an eastern barn owl Tyto javanica on the Patho Plains, northern Victoria

A small sample of eastern Barn Owl Tyto javanica pellets, from native grasslands on the Patho Plains in northern Victoria in February 2007, contained the remains of 48 prey individuals: 38 Australian Plague Locusts Chortoicetes terminifera, nine house Mice Mus domesticus and one Fat-tailed dunnart Sminthopsis crassicaudata. Such a high proportion of locusts in the eastern Barn Owl\u27s diet is noteworthy, and is discussed in the context of recent locust-spraying operations in the region.<br /

The establishment of large private nature reserves by conservation NGOs : key factors for successful implementation

Private nature reserves created by nongovernmental organizations (NGOs) are increasing, and their growing number and extent means that they can potentially contribute to biodiversity goals at a global scale. However, the success of these reserves depends on the legal, economic and institutional conditions framing their creation and management. We explored these conditions, and the opportunities and challenges facing conservation organizations in managing private nature reserves, across several countries, with an emphasis on Australia. Results from 17 semi-structured interviews with representatives of private conservation organizations indicated that while private reserves may enhance the conservation estate, challenges remain. Legal frameworks, especially tenure and economic laws, vary across and within countries, presenting conservation organizations with significant opportunities or constraints to owning and/or managing private nature reserves. Many acquired land without strategic acquisition procedures and secured funding for property acquisition but not management, affecting the long-term maintenance of properties. Other typical problems were tied to the institutional capacity of the organizations. Greater planning within organizations, especially financial planning, is required and NGOs must understand opportunities and constraints present in legislative frameworks at the outset. Organizations must establish their expertise gaps and address them. To this end, partnerships between organizations and/or with government can prove critical
