Lower Hunter and Central Coast Regional vegetation survey VIS_ID 2227

The NPWS were contracted by the Lower Hunter and Central Coast Regional Environment Management Strategy (LHCCREMS) to carry out vegetation survey and mapping across the region. The initial vegetation survey and mapping study formed the first major part of the data collection and analysis effort for this project.;\r\n;\r\nThe primary aims of the study were to ;\r\nproduce a detailed cross tenure map of the distribution of the vascular plant communities in the Lower Hunter and Central Coast region; ;\r\nprovide estimates of the distribution of the plant communities prior to the arrival of Europeans (pre-1750); ;\r\nutilise project methodologies which are consistent with the Comprehensive Regional Assessment (CRA) work conducted on public land in the region so that the two surveys can be amalgamated into a single database to greatly improve the resolution and usefulness of each; and provide a context for future studies so that data collection is compatible with, and contributes to the on-going development of a comprehensive regional database.;\r\n;\r\nThis work was then updated by Ecological in May 2003. This involved the integration of additional remnant mapping, review of mapping errors and correction, additional canopy cover mapping and other general refinements of the map layer, including information on canopy condition. Extant vegetation data mapped from aerial photos, combined with a pre1750 model of vegetation communities to produce an extant vegetation community map. Photos flown between 2000 & 2001 to produce extant vegetation map. This map then combined with the existing pre1750 vegetation community mapping undertaken by NSW NPWS to produce an extant vegetation community map. (VIS_ID 2227)新南威尔士州国家公园与野生动物服务局（NPWS）受下亨特与中央海岸区域环境管理战略（Lower Hunter and Central Coast Regional Environment Management Strategy, LHCCREMS）委托，对该区域开展植被调查与制图工作。本次项目的初期植被调查与制图研究，是该项目数据采集与分析工作的核心组成部分。 本研究的核心目标如下：一是绘制下亨特与中央海岸区域内维管植物群落分布的跨权属详细分布图；二是估算欧洲殖民者抵达前（1750年以前）该区域植物群落的分布情况；三是采用与该区域公共土地综合区域评估（CRA）工作一致的研究方法，以便将两次调查整合为统一数据库，大幅提升各自的分辨率与实用价值；四是为后续研究提供基准框架，确保数据采集与区域综合数据库的持续完善兼容并协同增效。 该项工作于2003年5月由Ecological公司完成更新。此次更新内容包括整合新增的残存植被制图、审查并修正制图误差、补充冠层覆盖度制图，以及对地图图层进行其他一般性优化，其中涵盖冠层状况相关信息。研究团队基于2000年至2001年间拍摄的航拍影像绘制现存植被数据，并结合1750年前的植物群落分布模型，生成现存植被群落分布图。随后，该地图与新南威尔士州国家公园与野生动物服务局（NSW NPWS）此前完成的1750年前植物群落制图相结合，最终生成现存植被群落分布图。（VIS_ID 2227）
