Vegetation map digitised from Porteners, M.F. (1998). The composition and extent of the present vegetation in Weetalibah Nature Reserve is described and mapped at 1:50 000 scale from quadrat samples, field traverses and aerial photograph interpretation. Three vegetation communities are described and 125 species (127 taxa) of vascular plants recorded from 38 families, several of which are at their north-western geographical limit or regionally restricted. One species is listed under Schedule 2 of the 1995 NSW Threatened Species Conservation Act." VIS_ID 1014

Vegetation associations of the Gwydir Watercourse were mapped from 1:50,000 scale colour aerial photographs taken during the period 26 August 2005 – 10 October 2005. VIS_ID 3921

The 2008 map of the vegetation communites of the Gwydir wetlands and floodplain (Bowen and Simpson 2009) was annotated for flooding frequency history, ecological importance and hydro-ecological functional group to determine the spatial distribution of ecological assets to inform the Valley Wide Floodplain Management Plan for the Gwydir.

The composition and extent of the present vegetation within Ginghet Nature Reserve (former property Wyninebah) is described and mapped by Porteners (2010). Twenty-five quadrat-based sites were sampled, with intensive field traverses, opportunistic sampling and aerial photograph interpretation. The survey sites were selected using stratified random sampling with replication where possible within the attribute class. The sites were distributed primarily to reflect the geomorphological gradients and soil changes across the study area, and to a lesser extent the structural variation of the vegetation. The data were then analysed using PATN multivariate analysis and identified five vegetation communities. 136 taxa of vascular plants were recorded from 36 families, eight of which are considered to be regionally significant. At each site, all vascular plant species were recorded within 20 by 20 metre (0.04 hectare) quadrats, and assigned a cover abundance rating based on a modified Braun-Blanquet six-point scale (Poore 1955). Bryophytes were not included in the survey. Vegetation structure was described by measuring the height and canopy cover of the dominant species in each stratum. Physiographic data additional to those defined by the stratification were also recorded, including soil type, landform, fire history and disturbance. All sites were located using a GPS, photographed and nested from the south-west corner Vegetation communities were mapped using colour aerial photographs at approximately 1: 50 000 scale (runs dated 3rd April 2005). The air photos formed the basis of the vegetation map polygons, supplemented by various orthophoto, SPOT satellite and other GIS layers. The photos were interpreted stereoscopically for patterns of vegetation and geomorphology, and then matched to the vegetation site data via direct visual assignment of floristic group attributes on the remote imagery. A provisional vegetation map was drafted and the study area traversed, with particular sites investigated to confirm polygon labels and resolve vegetation boundaries. The final vegetation polygons were transferred and visually corrected (orthorectified) to the orthophoto map and coded, ready for digitising into the GIS. The final vegetation map was digitised by DECCW Scientific Services (Dubbo) using ArcGIS. VIS_ID 3975

In 1996, extant vegetation associations of the Gingham and Lower Gwydir Floodplain, including the Gingham and the Lower Gwydir watercourses, were mapped from 1:25,000 colour aerial photographs. VIS_ID 815

The composition and extent of the present vegetation within Wongarbon Nature reserve is described and mapped. The existing plant community descriptions were classified into Plant Community Types. A total of 94.6 hectares were mapped and plant communities aligned. One quadrat-based site was sampled for full floristics, with an additional 2 condition-assessed sites, intensive field traverses, opportunistic sampling and aerial photograph interpretation. Three plant community types are described and 91taxa of vascular plants recorded from 32 families, including one listed threatened species. VIS_ID 4212

The vegetation of Gundabooka National Park in North Western NSW was assessed using intensive quadrat sampling and mapped using extensive ground truthing and interpretation of aerial photograph and Landsat Thematic Mapper satellite images in 2015. Two hundred and seventy six species of vascular plants were recorded from this survey from 62 families. Species recorded from previous studies but not noted in the present study have been added to give a total of 298 vascular plant species for the Park including 31 (10%) introduced species. Twenty one vegetation communities were identified and mapped, the most widespread being Eucalyptus populnea / Acacia aneura / Acacia excelsa open woodland and Acacia aneura tall shrubland. VIS_ID 3969
