NSW Extant Native Vegetation (Keith and Simpson 2006) - Version 002

Data represents NSW native vegetation extent, compiled from various vegetation maps using method outlined in (Keith and Simpson 2006). Data is also known as Keith and Simpson (2006) Version 002. Includes 4 layers i) woody native veg extent (natwdy_002), ii) non-woody native veg extent (rgrass002), and iii) secondary grassland extent (sgrass002). natwdy002 and rgrass002 are combined to create total NSW native veg extent (extveg_002). Data was developed for use in the July 2006 Biometric tool update, and specifically the update of the Over-Cleared Landscapes database, which underpins the NSW Property Vegetation Planning (PVP) process.\r\n\r\nSupersedes Keith (2004) and Pressey et al. (2000). Pressey et al. (2000) was the native veg extent product used to calculate native veg cover values for the Over-Cleared Landscapes Database prior to July 2006.

本数据集表征新南威尔士州（New South Wales, NSW）本土植被覆盖范围，整合自多套植被图件，采用Keith与Simpson（2006）提出的方法编制。该数据集亦被称为Keith与Simpson（2006）版本002。其包含4个图层：①木本本土植被覆盖范围（natwdy_002）、②非木本本土植被覆盖范围（rgrass002）与③次生草地覆盖范围（sgrass002）。将natwdy_002与rgrass002合并后，可生成新南威尔士州本土植被总覆盖范围（extveg_002）。本数据集开发初衷为服务2006年7月的生物计量工具更新，尤其针对《过度开垦景观数据库》的升级——该数据库是新南威尔士州地产植被规划（Property Vegetation Planning, PVP）流程的核心支撑基础。

本数据集取代了Keith（2004）与Pressey等（2000）的相关成果。在2006年7月之前，Pressey等（2000）的成果是用于计算《过度开垦景观数据库》本土植被覆盖数值的本土植被范围数据集。（另可参阅Keith与Simpson待刊研究）
