The Pre-clearing Natural Vegetation of the Southern Mallee Planning Region VIS_ID 1044

This paper outlines the background to the preparation of a digital pre-clearing vegetation map of the shires of Wentworth and Balranald (Southern Mallee). The data set was prepared in order to provide the Southern Mallee Regional Planning Committee with a platform from which to discuss the scope for any further clearing in tbe region. The Basin Care M305 Structural Vegetation digital coverage was used as the base layer, significantly modifying codes (1, 2, 3, 4, 7) that mapped areas where the native vegetation had been replaced. Satellite imagery, aerial photographs and historical reports where used to identify where and what the vegetation types were that had been cleared. A total of 33 1:100,000 M305 map sheets tiles were modified to complete the pre-clearing map of the region. A summary of the status of each vegetation community in the region is outlined showing the extent of clearing and reservation.\r\n\r\nVIS_ID 1044

本论文阐述了温特沃斯（Wentworth）与巴勒兰纳德（Balranald）两郡所在的南马利（Southern Mallee）地区数字化清理前植被地图的编制背景。本数据集的编制旨在为南马利地区规划委员会提供研讨平台，以讨论该区域后续开展植被清理的可行空间。本数据集以 Basin Care M305 结构植被数字化覆盖图层作为基础底图，并对标记原生植被已被替换区域的编码（1、2、3、4、7）进行了大幅修订。研究借助卫星影像、航空照片与历史报告，识别出已被清理的植被类型及其分布区域。共计修订了33幅1:100000比例尺的M305地图分幅，最终完成该区域的清理前植被地图。本文还概述了该区域各植被群落的现状，展示了植被清理与保护预留的范围。
