Domestic Livestock

In Australia, particularly in the southern rangelands, large populations of native and feral herbivores (including kangaroos, goats, rabbits, pigs, donkeys and camels, depending on the location) co-exist with domestic livestock. In recent decades the concept of ‘total grazing pressure’ has been developed, and widely accepted, to denote the total forage demand of all vertebrate herbivores relative to the forage supply. This concept provides a framework within which both domestic and non-domestic species can be managed to allow commercially viable livestock production, landscape maintenance or restoration and species conservation. The concept should have relevance wherever pest animal control programs, biodiversity conservation, or commercialisation of wildlife are conducted in conjunction with extensive livestock production. The rationale for the compilation of the Special Issue is outlined.

Domestic Livestock

Sustainable grazing in the nationally iconic southern rangelands of Australia requires landholders to actively manage the grazing pressure from both domestic livestock and non-domestic herbivores. Landholders have primary responsibility for controlling the non-domestic herbivores. In doing so, they must meet the Australian public’s expectations for resource conservation (mainly a public good) and animal welfare. Governments are also involved in the management of non-domestic herbivores via native and feral animal legislation and control programs. The Australian public will not accept cruelty to animals, perceived or otherwise. In this paper we explore the challenges faced by landholders in their attempts to manage the grazing pressure from native herbivores, particularly kangaroos, feral goats and feral pigs, while meeting the Australian public’s expectations for animal welfare. Landholders typically live on extensive properties and their capacity to manage these is influenced by high climate variability, low labour availability, commodity price fluctuations and limited capital available for investment in new technologies. The additional requirement to reduce the grazing pressure from kangaroos, feral goats and feral pigs is a significant burden on already time-poor landholders. Hence, there is a critical disparity between landholders’ capacity and their responsibility to effectively manage the non-domestic herbivores on their properties. We suggest that current expectations of landholders to deliver public benefits by publicly acceptable practices are unreasonable. Further, we suggest that governments should accept more responsibility for managing non-domestic grazing pressure. The concept of duty of care to land management provides a means by which a more appropriate division of responsibilities between landholders and government could be achieved to ensure that valued attributes of this iconic Australian landscape are retained.

Abstract The Red fox (Vulpes vulpes) has established large populations in Australia’s urban and rural areas since its introduction following European settlement. The cryptic and highly adaptable nature of foxes allows them to invade cities and live among humans whilst remaining largely unnoticed. Urban living and access to anthropogenic food resources also influence fox ecology. Urban foxes grow larger, live at higher densities, and are more social than their rural counterparts. These ecological changes in urban red foxes are likely to impact the pathogens that they harbour, and foxes could pose a disease risk to humans and other species that share these urban spaces. To investigate this possibility, we used a meta-transcriptomic approach to characterise the virome of urban and rural foxes across the Greater Sydney region in Australia. Urban and rural foxes differed significantly in virome composition, with rural foxes harbouring a greater abundance of viruses compared to their urban counterparts. We identified ten potentially novel vertebrate-associated viruses in both urban and rural foxes, some of which are related to viruses associated with disease in domestic species and humans. These included members of the Astroviridae, Picobirnaviridae, Hepeviridae, and Picornaviridae as well as rabbit haemorrhagic disease virus-2. This study sheds light on the viruses carried by urban and rural foxes and emphasises the need for greater genomic surveillance of foxes and other invasive species at the human–wildlife interface.

Threatening Processes

History and pre-history tells us that Australian mammals have fared poorly through their association with humans. First there were the Pleistocene megafauna extinctions as Aborigines colonised the continent followed later by extinction of the large marsupial carnivores after introduction of the Dingo. European colonisation first appeared to favour many native mammals but later led to declines and extinctions at an unprecedented rate. The shock waves of these massive changes are most probably still reverberating across the landscape and need consideration in our approach to species conservation. Species recovery is a new and important science. Current management efforts focus on broad scale baiting of Foxes, translocation of endangered species to offshore predator-free islands, and their protection in predator enclosures. A national and more corporate approach to species conservation has arisen from national species recovery teams. Sharing of resources, particularly technical information on threat management, is critical to effective species recovery. This is especially important in forging the desperately needed break-through in control of Feral Cats. History tells us that disturbance of one component of the ecosystem will often provoke changes in other areas. The current intensive focus on Foxes demands careful monitoring of the general system as an early warning of developing problems. Study of the interactions between Foxes, Dingoes, Feral Cats and Rabbits are needed to discover the likely outcomes of control programs, particularly in the more arid regions where all four species coexist. Experimental reintroduction of yet untried species occupying niches yet to be examined by this technique may expose additional but more subtle threatening processes.

Poplar box (Eucalyptus populnee) woodlands mainly occuron duplex, clay and red earth soils between the 300 mm and 750 mm rainfall isohyets. The poplar box lands have been occupied for from 100 to 150 years and have been modified extensively through tree felling, ringbarking, clearing, cultivation, burning and grazing by domestic livestock. The current land use is described for six vegetation groups which together comprise the poplar box lands. The eastern areas of the poplar box lands are mainly used for intensive agriculture based on wheat. barley and grain sorghum, with small areas sown to c~ops of high water demand. Mixed farming involves dairying (in Queensland) and fat lambs (in New South Wales) and broad-acre cereal and fodder cropping. Sheep and cattle grazing replace intensive crop production as the rainfall decreases. In all areas used for cropping the stability and fertility of the soil are of paramount importance in maintainihg production. The use of woodlands in areas of lower rainfall can lead to deterioration of the resource and to the encroachment of woody native species into the grazing lands. Because cropping is unreliable the opportunity to use cultivation to control woody regrowth is reduced. In central areas much of the land can be sown to improved pastures, but in western areas diversification is limited by the low rainfall and land use is restricted to grazing, initially only by sheep but now by sheep and cattle. Particularly in western New South Wales the increase in unpalatable shrubs and the decrease in available forage has resulted in low stocking rates, and high grazing pressure, making reclamation and pasture improvement difficult. In consequence many enterprises are becoming uneconomic.

Conservation Policies

Urbanization is a major driver of environmental change and is closely linked to the future of biodiversity. Cities can host a high richness of plants and animals, and this urban biodiversity supports multiple regulating, provisioning and cultural ecosystem services. Developing biodiversity-friendly cities is thus inextricably linked to sustainable urban development and human wellbeing. The contributions to this Special Issue on “Biodiversity Conservation and Sustainable Urban Development” in the journal Sustainability illustrate the role of urban environments as pressures on biodiversity, and envision pathways towards developing more biodiverse urban environments that are accepted and supported by people. Contributions reveal promising opportunities for conserving biodiversity within many urban landscapes. The insights from this Special Issue can support urban conservation policies and their implementation in the development of sustainable cities.

Working Together

In the years that have passed since the 2011 Great East Japan earthquake, many new findings, insights and suggestions have been made in disaster observation, sensing, simulation, and damage determination on the damage scene. Based on the lessons, challenges for disaster mitigation against future catastrophic natural disasters such as the anticipated Tokyo metropolitan and Nankai Trough earthquakes are made on how we will share visions of potential impact and how we will maximize society's disaster resilience. Much of the ``disaster big data" obtained is related to the dynamic flow of large populations, vehicles and goods inside and outside affected areas. This has dramatically facilitated our understanding of how society has responded to unprecedented catastrophes. The key question is how we will use big data in establishing social systems that respond promptly, sensibly and effectively to natural disasters how this understanding will affect adversity and resilience. Researchers from a wide variety of fields are now working together under the collaborative JST CREST project entitled ``Establishing the most advanced disaster reduction management system by fusion of real-time disaster simulation and big data assimilation." One objective of this project is to identify potential disaster scenarios related to earthquake and tsunami progress in a chained or compound manner and to create new techniques for responsive disaster mitigation measures enabling society to recover. This special issue on disaster and big data consists of 11 papers detailing the recent progress of this project. As an editor of this issue, I would like to express our deep gratitude for the insightful comments and suggestions made by the reviewers and the members of the editorial committee.
