Lower Hunter and Central Coast Regional vegetation survey VIS_ID 2225

"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.";\r\n;\r\nVIS_ID 2225

新南威尔士国家公园与野生动物服务局（NPWS, National Parks and Wildlife Service）受下亨特与中央海岸区域环境管理战略（LHCCREMS, Lower Hunter and Central Coast Regional Environment Management Strategy）委托，开展该区域的植被调查与制图工作。本次初始植被调查与制图研究，为本项目的数据采集与分析工作构成了第一核心板块。

本研究的核心目标包括：
1. 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地图；
2. 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；
3. 采用与该区域公共土地综合区域评估（CRA, Comprehensive Regional Assessment）工作一致的项目方法，以便将两次调查整合至统一数据库，大幅提升两份数据集的分辨率与实用价值；同时为后续研究提供参照框架，确保数据采集可兼容并助力综合区域数据库的持续迭代完善。

此项工作随后由Ecological公司于2003年5月完成升级优化，具体内容包括整合额外的剩余植被制图、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精细化处理，例如添加冠层状况相关信息。研究团队利用2000年至2001年获取的航拍影像绘制现存植被地图，并将该数据与1750年前植被群落模型相结合，生成现存植被群落地图。随后，该地图与新南威尔士国家公园与野生动物服务局（NPWS）此前完成的1750年前植被群落制图相结合，最终生成新版现存植被群落地图。
