Sydney Harbour Foreshore and Estuarine Vegetation 2006. VIS_ID 4030

The Sydney Harbour Foreshore and Estuarine Vegetation dataset was generated by Botanic Gardens Trust, Sydney (BGT) for the data owners, NSW Maritime, and is subject to NSW Maritime data license agreement. \r\n\r\nSydney Harbour and its tributaries form an important and dynamic ecosystem with substantial natural values while continuing to provide a focus for extensive urban development, valued open space and recreational opportunities as well as being maintained as a ‘working harbour’.\r\n\r\nThe estuarine components of this project cover all estuarine areas of Sydney\r\nHarbour, Parramatta River and tributaries. This includes the area from North Head to South Head, including upstream to the natural tidal limits of Middle Harbour (St. Ives and Davidson) to the weir on Lane Cove River; the eastern-most weir at Parramatta; and to Granville at Duck River and Duck Creek.\r\nThe foreshore components of this project include, as a minimum, the foreshore land from Mean High Water Mark (MHWM) to 40m landward. In some instances the mapping was extended upslope beyond 40m to a maximum of 200m, where\r\ncontiguous vegetation was present. The shoreline of the study area is a little over\r\n360km in length.\r\nAlthough the estuary and its immediate foreshore are the focus of this study it is not possible to protect the significant natural values without consideration of the broader catchment and its contribution to the functioning of this ecosystem. The catchment has an approximate surface area of 217 km2.\r\n\r\nAPI (aerial photographic interpretation) and ground truthed vegetation mapping of the Sydney Harbour foreshore at a presentation scale of 1:2000 was necessary to prioritise property-scale management objectives of NSW Maritime and to place these objectives in a catchment perspective. Native terrestrial vegetation communities were categorised to match the categories of the Cumberland Plains 1:16,000 vegetation map, but were further divided on structural characteristics. API was performed using the 2003 15cm pixel ortho-rectified colour ECW format aerial photo mosaics of Sydney Harbour. \r\n\r\nThe non veg areas of the foreshore were removed from the dataset - see lineage for more detail.\r\n\r\nVIS_ID 4030

悉尼港沿岸与河口植被数据集由悉尼植物园信托基金（Botanic Gardens Trust, Sydney, BGT）为数据所有者新南威尔士海事局（NSW Maritime）制作，受新南威尔士海事局数据许可协议约束。

悉尼港及其支流构成了一处重要且富有活力的生态系统，兼具极高自然价值；同时它仍是大规模城市开发的核心区域，拥有广受赞誉的开放空间与休闲资源，并始终作为“作业港”维持运转。

本项目的河口覆盖范围涵盖悉尼港、帕拉马塔河及其支流的全部河口区域，具体包括从北角至南角的海域，上溯至中港（圣艾夫斯与戴维森）的自然潮汐上限至莱恩科夫河上的堰坝、帕拉马塔最东端的堰坝，以及达克河与达克溪的格兰维尔段。

本项目的沿岸区域最低范围为平均高潮位（Mean High Water Mark, MHWM）向陆侧延伸40米的沿岸土地；在部分存在连片植被的区域，制图范围可进一步向坡上扩展至最大200米。本研究区域的海岸线总长略超360公里。

尽管本研究聚焦于河口及其紧邻沿岸区域，但若不考虑更大范围的流域及其对该生态系统运转的贡献，便无法有效保护其重要自然价值。该流域的表面积约为217平方公里。

为优先确定新南威尔士海事局的场地级管理目标，并从流域视角统筹这些目标，需以1:2000的出图比例尺开展悉尼港沿岸植被的航空摄影解译（aerial photographic interpretation, API）与地面验证制图。本土陆生植物群落首先匹配坎伯兰平原1:16000植被图的分类体系，再依据结构特征进一步细分。航空摄影解译工作基于2003年拍摄的15厘米像素分辨率正射校正彩色ECW格式悉尼港航空影像镶嵌图完成。

数据集已剔除沿岸非植被区域——详细信息请参阅数据谱系说明。
