Historic Woody Vegetation Mapping of the NSW Wheat-belt VIS_ID 1604

The vegetation of the Central Division of NSW was classified and mapped (Cobar-Nyngan-Gilgandra), Nymagee-Narromine-Dubbo 1:250 000 map sheets) as part of the NSW NPWS wheat-belt mapping series. The vegetation classification was derived using traditional API and quantitative analysis of data from 428 field sites. Analyses included heirarchical classification in PATN to define floristic groups, then Fidel and ANOSIM to elucidate the characteristic species of the groups and explore the consistency of these relationships and various levels of similarity. Maps and descriptions show the floristic composition and structure, the geographic distribution of assemblages, the current extent, and shape and degree of connectivity of vegetation and changes in native woody vegetation cover over time.

作为新南威尔士州（New South Wales, NSW）国家公园与野生动物服务局（National Parks and Wildlife Service, NPWS）小麦带制图系列的一部分，研究人员对新南威尔士州中部区域的植被开展了分类与制图工作，覆盖Cobar-Nyngan-Gilgandra、Nymagee-Narromine-Dubbo共4幅1:25万比例尺图幅。本次植被分类基于传统航空摄影解译（Aerial Photo Interpretation, API）及对428个野外调查样点的定量分析完成。分析流程包括在模式分析包（Pattern Analysis Package, PATN）中执行等级分类以界定植物区系群，随后借助Fidel与相似性分析（Analysis of Similarities, ANOSIM）阐明各植物区系群的特征物种，并探究此类群关系的一致性以及不同层级的相似性水平。本数据集的地图与描述内容涵盖了植被的植物区系组成与结构、群落组合的地理分布、当前植被覆盖范围、植被的形态特征与连通程度，以及本土木本植被覆盖度随时间的变化情况。(VIS_ID 1604; ANZNS0208000147)
