Abstract
This is a journal article that outlines the potential linkages between calibrated imagery archives and natural resource management. Abstract: Increasingly environmental decision makers are demanding detailed spatial coverages with high temporal frequency to assess trends and changes in the extent and condition of identified targets such as; wetlands, species habitats, farmlands, forests, rangelands, soil, water and vegetation. To a large extent dynamic land cover information can meet these requirements. Satellite images are being standardised and gathered into satellite image archives. From these nation-wide land cover datasets are being produced. these datasets retain the original pixel size of the satellite imagery allowing for analysis from the paddock to the national scale. These datasets are being validated using field reference sites and existing ecological and biophysical GIS datasets. Time series of land cover datasets are then being analysed to give estimates of land cover change through time. This is providing land managers with unprecedented synoptic and dynamic vegetation perspectives on which to base their decisions. Access to these time series information provides an unprecedented opportunity to better focus natural resource management (NRM) in Australia. Opportunities include: assessing the extent and condition of key assets, prioritising investment in key localities and time periods, improved targeting of scarce public funding and monitoring and evaluating the outcome of this investment to assist land managers to make improvements in land management practices to meet wider community social, economic and environmental goals. We use two case studies; the management of wildfire and soil erosion, to demonstrate the application of dynamic land cover information for improving NRM outcomes. We discuss the benefits of using this information for monitoring and reporting on seasonal, annual and decadal dynamics that impact on natural resource management assets. We also highlight the value of establishing partnerships with local land managers, regional bodies and State and the Australian Government agencies to improve the accuracy of the dynamic land cover information. Dynamic land cover information has potential to improve the design and reporting of national NRM programs.
