NVMP mapping for the Bogan Gate map sheet VIS_ID 1595

Brief description

Native vegetation, including forest, woodland and grass/forbland assemblages, is described and mapped for the Bogan Gate, Boona Mount, Condobolin, Dandaloo, Tottenham and Tullamore 1:100 000 map sheets, located in the central western region of New South Wales. This area encompasses parts of six Local Government Areas: Bogan, Forbes, Lachlan, Narromine, Parkes and Warren. Spatial delineation of map units was accomplished using stereoscopic air photo interpretation, assisted by satellite imagery. Preliminary coding was applied based on vegetation patterns and then revised subsequent to data manipulation and analyses. Comprehensive plot-based floristic data were collected for 850 plots using a random stratified sampling procedure. An environmental stratification based on soil landscapes, temperature and rainfall guided sampling location and intensity. Additional mask layers were applied to distinguish between 'woody' and 'non woody' vegetation and each layer independently sampled. Plot data were classified into 41 woody and 20 non-woody floristic groups using pattern analysis within PATN. Additional analysis techniques included ordination; fidelity, homogeneity, nearest neighbour and indicator species analysis. Multi-Response Permutation Procedures were used to evaluate the degree to which classificatory groups were recognised at a similar level of within group similarity. Floristic groups are defined using structural dominance, diagnostic/indicator species and character species data. AiPI units were interrogated with respect to floristic groups to produce the map units. A total of 21 woody map units were developed to represent woody assemblages. Six broad map units based on landform and land use patterns represent non-woody assemblages. Map units are described with respect to structure, floristic composition and landform unit.
