Forests of East Australia: The 35th Biodiversity Hotspot

The newly identified “Forests of East Australia” Global High Biodiversity Hotspot corresponds with two World Wildlife Fund (WWF) Ecoregions: the Eastern Australian Temperate Forests and Queensland’s Tropical Rain forests. The region contains more than 1,500 endemic vascular plants, meeting the criterion for global biodiversity significance, and more than 70% of natural areas have been cleared or degraded, meeting the criterion for a hotspot. The hotspot, although covering a large latitudinal range (15.5°–35.6° South), has a predominantly summer rainfall pattern with increasing rainfall seasonality northwards into tropical areas of north Queensland. It covers large tracts of elevated tablelands and drier inland slopes, particularly in New South Wales, where it extends inland beyond the New England Tablelands and the Great Dividing Range. Varied soils result in a mosaic pattern of vegetation. Sclerophyllous communities dominated by Australia’s iconic plant, the gum-tree (Eucalyptus species), are the most prevalent vegetation type. Significant areas of rain forest exist throughout the region, much of which has persisted continuously since Gondwanan times, providing a rich living record of evolution over more than 100 million years. The human population of the hotspot as of 2006 was over nine million, with a population density of 36 people per square kilometer, mainly concentrated along the coast. About 18% of the land area is under some form of formal protection for its natural values. Gaps in the protected area network include some centers of plant endemism and some areas of critical habitat for threatened species. Whole of landscape conservation initiatives are enhancing connectivity throughout the Great Dividing Range through voluntary protection and restoration programs.

Informing major government programs for rural transport infrastructure in northern Australia

New or expanded agricultural industries in northern Australia require efficient and reliable supply chains and transport to domestic and international markets. A major challenge in the north is long transport distances of over 1000km between production and markets, along a sparse rural road/rail network that is largely unsealed and disrupted by seasonal flooding. To provide a comprehensive view of transport logistics costs and benefits due to infrastructure investments and regulatory changes in agriculture supply chains, the Australian Government commissioned CSIRO to develop the Transport Network Strategic Investment Tool (TraNSIT). TraNSIT optimises transport routes for up to hundreds of thousands of enterprises and millions of vehicle trips between farms and their markets, providing modelled input into operational and investment decisions. As part of a major Australian Government initiative, TraNSIT was used to directly inform the A

A catchment-based approach to mapping hydrological ecosystem services using riparian habitat: A case study from the Wet Tropics, Australia

Abstract Transport infrastructure is essential to moving over 85 million tonnes of agricultural products and 30 million cubic metres of timber from farms and production areas to domestic and international markets each year in Australia. Agriculture supply chains in Australia are characterised by long distances with transport costs accounting for up to 40 percent of the market price. Targeted infrastructure investment and/or regulatory changes can substantially reduce transport-related logistics costs. To provide a comprehensive view of transport logistics costs and benefits due to infrastructure investments and regulatory changes in agriculture and forestry supply chains, CSIRO developed a computer-based tool – the Transport Network Strategic Investment Tool (TraNSIT). TraNSIT optimises transport routes for upto hundreds of thousands of enterprises and millions of vehicle trips between farms and their markets, providing information on routing to maximise cost efficiencies. Through an Australian Government initiative, TraNSIT was applied to over 30 commodities representing 98% of Australian agricultural and plantation forestry volume transported by road and rail. TraNSIT is now a comprehensive logistics tool that has been applied to the largest agricultural supply chain dataset ever assembled in Australia. This paper provides an overview of TraNSIT, its adaptation to agriculture and forestry logistics as part of the project, and its application to several case studies in Australia including new road links, rail versus road and flooding.
