Abstract |
In 1986, the River Murray Riparian Vegetation Survey was initiated by the Murray-Darling Basin Commission (MDBC) to assess the present status of the vegetation along the River Murray, to identify causes of degradation, and to develop solutions for its rehabilitation and long term stability. The Study area was the floodplain of the River Murray and its anabranches, including the Edward-Wakool system, from below Hume Dam to the upper end of Lake Alexandrina, a total of nearly 9,000 square kilometres (900,000 hectares). The survey was conducted by Margules and Partners Pty Ltd, P and J Smith Ecological Consultants, and the then Victorian Department of Conservation, Forests and Lands (DCFL). The results were then compiled by DCFL, a report published (see References) and a GIS was constructed. Please note that the vegetation mapping uses a mixed floristic/structural classification.

Lineage |
Collection Method - the survey A comprehensive bibliography was compiled on the floodplain vegetation, its environment and the impact of human activity. The literature was reviewed and summarised. A field survey was carried out, visiting 112 sites throughout the study area and collecting vegetation data from 335 plots. Brief studies were made of the effects of river regulation and salinisation at specific sites. Collection Method - Digitising After mapping from a variety of sources was completed by the consultant, Adam Choma of the then Victorian Department of Conservation, Forests and Lands (DCFL), compiled the riparian vegetation mapping and completed the digitising in 1990. Adam's description of how the data was digitised follows: " 1:100 000 AUSLIG topographic maps were used as the base for all work. " Film transparencies from AUSLIG were used in most cases but occasionally paper maps were used. " Maximum acceptable RMS error was 0.002 on all digitising (this value is scale independent). " Old Forestry Commission maps (one of the data sources) were often inaccurate at the presentation scale of 1:15840 and needed to be edited into shape. " The other major source of information was NSW Department of Lands black and white aerial photography at the scale of 1:45 000. This was ground checked. " Topographic base maps from AUSLIG were found to be very poor with, for example, poor edge-matching, roads discontinuous across map sheets and roads changing type (eg. sealed to dirt) across map sheet boundaries. " All riparian vegetation maps were checked twice to ensure any error was in acceptable limits. The data was then reprojected by the MDBC from UTM AGD66 datum and Australian National spheroid to UTM WGS84 datum and spheroid. 1/11/2007 - River reaches merged into single feature class, topology checking and attribute update. |
