A remote sensing approach for mapping and classifying riparian gully erosion in Tropical Australia

Recent aerial and ground reconnaissance through the Gulf of Carpentaria has identified riparian gully erosion as one of the dominant contemporary sediment sources to many of the large rivers draining into the Gulf of Carpentaria. Similar processes have also been identified in the Savannah regions of the NT and WA, particularly the Victoria and Ord Rivers. It has also been suggested that broad scale gully erosion of this type and associated local (more)...

A remote sensing approach for mapping and classifying riparian gully erosion in Tropical Australia

Alluvial gully erosion has been one of the dominant contemporary sediment sources in many of the large rivers draining into the Gulf of Carpentaria, yet, fundamental questions persist concerning the phenomenon both in terms of causal mechanisms and extent. In this project a baseline assessment of alluvial gully erosion in four tropical savannah rivers was undertaken resulting in both the development of a gully erosion conceptual model and an assessment of the spatial extent of gully erosion.

A Landscape Approach to Determine the Ecological Value of Paddock Trees

Summary Report Years 1 and 2

This project aimed to assess the ecological value of scattered paddock trees at a landscape scale, using two approaches. This first was to undertake an intensive mapping program for two study areas in South Australia, equating to an area of 378,000 hectares, and the second to undertake a field study to assess how birds use paddock trees at various levels of tree cover.

Advanced airborne technologies for mapping and monitoring native Australian vegetation

Airborne sensors can be used by natural resource managers and researchers to collect data about things which can be seen, such as vegetation cover, as well as characteristics like canopy condition and water use, which are not visible. Importantly, faster and more accurate data collection over large areas can be achieved by combining light detection and ranging (lidar) with other airborne technologies which include multi and hyper spectral scanners, digital video and still photography. Lidar can be (more)...

National estuarine, coastal and marine habitat map series

This project aimed to discover and negotiate access to all existing GIS (electronic) ECM habitat maps, collate the GIS maps and then apply the relevant national classification schemes, develop new nationally consistent habitat classification schemes where not available and conduct quality assurance and document the national map series. The ECM national habitat map series consists of two (more)...

The potential to map the adaptive capacity of Australian land managers for NRM policy using ABS data

Resilience, vulnerability and adaptive capacity are terms increasingly used in rural policy, but rarely defined or converted into practical measures that support policy design and implementation. Adaptive capacity measures based on rural livelihoods analysis have been developed and trialled using ABARE data for broadacre industries. This paper provides a preliminary assessment of the potential to expand the application to all agricultural industries and to broaden the range of (more)...

Australian land cover mapping

Proceedings of a workshop to discuss interest in land cover mapping

Land cover had been identified as a critical information need for national and regional reporting and decision making by the National Land & Water Resources Audit (the Audit), Geoscience Australia (GA), the Bureau of Rural Sciences (BRS), the Commonwealth Scientific Industrial Research Organisation (CSIRO) and most of the national coordinating committees (representing (more)...

National intertidal/subtidal benthic (NISB) habitat classification scheme v1.0

Intertidal and shallow water benthic habitat mapping is conducted in all Australian states and the Northern Territory by a variety of agencies and for a range of purposes. The various classification schemes used are designed for these specific purposes and there is not necessarily consistency between the resultant mappings. Typically, the States and NT have focused their mapping efforts on defining habitat extent at various resolutions (see discussion below), while Commonwealth (more)...

Wet tropics - regional report card (Apr 2007)

This regional report card provides a two page summary for each of the Wet Tropics assets. The first page is devoted to a description outlining the goals for, and the status and trends in, the condition of the asset. These sections have been developed by the FNQ NRM Ltd theme leaders, and show the steps and actions that FNQ NRM Ltd are taking that will lead to the assessment of asset condition. The key (more)...
