In 1986, the River Murray Riparian Vegetation Survey was initiated by the Murray-Darling Basin Commission 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.

Native vegetation was delineated into stands using feature recognition software. A hybrid classification method that combined spatial modelling and visual interpretation was used to combine the features and create a vegetation map. SPOT 5 and Landsat satellite imagery was used in the creation of image objects. The spectral response of individual SPOT 5 scenes varied widely across the catchment so it was not used in the classification of vegetation type. Spatial layers used in the classification included a Digital Elevation Model (DEM), Landsat reflectance data, radiometric data and soil and climate layers, all of which are available for the entire State. Over 340 new full floristic survey sites were commissioned and the results were combined with 900 existing survey site records to create training areas for spatial modelling. Each survey site was assigned a New South Wales Vegetation Classification and Assessment (NSWVCA) vegetation type. The relationship between survey sites and spatial layers was explored by using machine learning software and vegetation type was classified using an object-based nearest neighbour approach. The catchment was divided into three discrete spatial models with separate training and validation survey sites. Model performance was assessed on the basis of the number of NSWVCA types mapped correctly in five classes of precision. The percentage of correctly modelled vegetation types ranged between 58% and 68%. Several vegetation community types were not able to be modelled (e.g. chenopods) or were poorly modelled due to lack of sample data. These communities were added or amended based on the visual interpretation of remotely sensed data. The amended map was assessed against a limited subset of independent survey data. The percentage of correctly mapped vegetation types in five classes of precision ranged between 72% and 78%. The mapping was presented in a geodatabase, which allows for user-generated updates so that the product can evolve as more field data are collected. ROFF, A., SIVERTSEN, D., AND DENHOLM, B. 2010.

A mosaic vegetation map based on ‘best available’ vegetation mapping data sets compiled for the Murrumbidgee Catchment Management Authority (CMA). A seamless vegetation map was produced by allocating each of the vegetation types within the composite data sets to one of the NSW Keith Vegetation Classes. Mapping accuracy and resolution within the composite maps varied significantly. Where there was overlap the data set considered to be most accurate took precedence, replacing the less accurate data.

Native vegetation mapping of the Murray River National Park (Vic), covering part of Barmah Forest area.; ; This map was prepared to specifically show the spatial delineation of stem density and canopy condition categories of vegetation in the Barmah and Millewa Forest areas. This map was prepared using aerial photo interpretation (API) of ADS40 digital aerial photography captured in 2010. ; ; The map was prepared by updating (linework and attribution) of existing vegetation mapping produced in 2005 by Doug Frood (Frood 2007).; ; Barmah National Park (Vic) and the Murray River Park (Vic) are collectively known as the Barmah Forest.

Native vegetation mapping of the Millewa Forest Section of the Murray Valley National Park (NSW).; ; This map was prepared to specifically show the spatial delineation of stem density and canopy condition categories of vegetation in the Barmah and Millewa Forest areas at 2010. This map was prepared using aerial photo interpretation (API) of ADS40 digital aerial photography captured in 2010.; ; The map was prepared by updating (linework and attribution) of existing vegetation mapping produced in 2005. The unpublished Binns map (Doug Binns of Forests NSW) was used a as source for underlying line work and vegetation type classification. The Binns map is a compilation of the best available vegetation mapping prepared for the NSW Natural Resources Commission (NRC NSW Riverina Red Gum Forests Assessment (NRC 2009). http://www.nrc.nsw.gov.au/content/documents/Red%20gum%20-%20FAR%20-%20Complete.pdf For the Millewa Forest area Binns sourced his linework from the Native Vegetation Mapping Program Deniliquin 1:100,000 map sheet (DLWC 2005).; ; In an effort to protect areas of the Riverina red gum forests the NSW Government gazetted Millewa forest as part of the Murray Valley National and Regional Parks under the NSW National Parks and Wildlife (Riverina Forests) Act 2010.

These data were converted from the originally delivered Microsoft Access PLOTs database from the Vegetation Mapping Inventory Project of Tumacacori National Historical Park. These comma-delimited data tables contain(s) vegetation mapping plot classification and accuracy assessment data, as well as summary information about the data itself. If a table is empty, then it was empty in the original database.

The files linked to this reference are the geospatial data created as part of the completion of the baseline vegetation inventory project for the NPS park unit. Current format is ArcGIS file geodatabase but older formats may exist as shapefiles. Using field sample site information, the Alliance/Association classes were extrapolated to polygons sharing like aspects in the same regional area. A preliminary vegetation map was created and then reviewed by TNC field biologists for accuracy. If necessary, revisions to the delineations or the computer model were made and another map was produced for review. This process was repeated until the TNC biologists approved of all classification assignments.
