    Hydrological and land use changes can affect species in human altered landscapes. Typically the impacts of hydrological and land use changes are examined separately, with hydrological determinants used to explain the distribution of species in water dependent and aquatic habitats and land use factors used to examine terrestrial species. However, given the connectedness of aquatic and terrestrial habitats, stressors originating in one domain may be important in the other.

    Government agencies in many countries are encouraging rural landholders to improve their land management practices in order to improve the health of the natural environment. The level of adoption of improved practices by landholders is, however, highly variable. Understanding the diversity of rural landholders is an important step in increasing the uptake of improved land management practices. In this study, we investigate the factors that influence landholders to adopt recommended practices and use this to provide insights into how to encourage greater adoption of these practices.

    Forest policy decisions are often a source of debate, conflict, and tension in many countries. The debate over forest land-use decisions often hinges on disagreements about societal values related to forest resource use. Disagreements on social value positions are fought out repeatedly at local, regional, national, and international levels at an enormous social cost. Forest policy problems have some inherent characteristics that make them more difficult to deal with. On the one hand, forest policy decisions involve uncertainty, long time scales, and complex natural systems and processes.

    Pricing greenhouse gas emissions is a burgeoning and possibly lucrative financial means for climate change mitigation. Emissions pricing is being used to fund emissions-abatement technologies and to modify land management to improve carbon sequestration and retention. Here we discuss the principal land-management options under existing and realistic future emissions-price legislation in Australia, and examine them with respect to their anticipated direct and indirect effects on biodiversity.

    Should north Australia's extensive populations of feral animals be eradicated for conservation, or exploited as a rare opportunity for Indigenous enterprise in remote regions? We examine options for a herd of banteng, a cattle species endangered in its native Asian range but abundant in Garig Gunak Barlu National Park, an Aboriginal land managed jointly by traditional owners and a conservation agency in the Northern Territory of Australia.

    SUMMARYPrescribed burning in forestry is a valuable land management tool that has been extensively used in Australia, Eurasia, and North America. Nevertheless, fire is inherently dangerous and may impose risk upon humans, properties, and other natural resources. With the case of southern United States, the objective of this study is to assess the trend of administrative law reforms for forestry prescribed burning within the theoretical framework of management-based regulation.

    Hydrological processes within riparian environments worldwide are impacted when introduced species invade. Monitoring and management at substantial expense, are subsequently required to combat deleterious effects on the environment and stream hydrology. Willow species (Salicaceae: Salix spp.) introduced into Australia have spread throughout many riparian systems causing adverse environmental impacts, with high rates of water extraction when located within stream beds (in‐stream willows) thus altering hydrology.

    Transferable offsets are a means of mitigating the adverse environmental impacts of resource developments. Based on insights from institutional economics, there are three elements that need to be in place for offsets to be effective: (1) property rights over the mitigating good can be defined and assigned; (2) a difference exists between the marginal cost of supplying the mitigating good and the community's marginal value for it; and (3) the transaction costs of exchanging the mitigating good are less than the trade benefit.

    Several approaches have been proposed for accounting for temporary carbonsequestration in land-use change and forestry projects that are implemented to offsetpermanent emissions of carbon dioxide from the energy sector. In a previous paper,we evaluated the incentives provided by some of these approaches. In this paper, weinvestigate further what we call the “ideal” accounting system, where the forest ownerwould be paid for carbon sequestration as the service is provided and redeempayments when the forest is harvested and carbon is released back into theatmosphere.

    Burnt area data, derived from the National Oceanic and Atmospheric Administration (NOAA) Advanced Very High Resolution Radiometer (AVHRR) imagery, are validated in 11 regions of arid and semi-arid Australia, using three separate Landsat-derived burnt area data sets. Mapping accuracy of burnt extent is highly variable between areas and from year to year within the same area. Where there are corresponding patches in the AVHRR and Landsat data sets, the fit is good. However, the AVHRR data set misses some large patches.
