Northern Rivers CMA GDEs (DRAFT DPI pre-release)

## **Abstract** \n\nThis dataset was supplied to the Bioregional Assessment Programme by a third party and is presented here as originally supplied. Metadata was not provided and has been compiled by the Bioregional Assessment Programme based on known details at the time of acquisition.\n\n\n\nThis dataset contains an ESRI shapefile with polygons covering Groundwater Dependant Ecosystems in the Northern Rivers CMA. It is a DRAFT DPI pre-release version.\n\n\n\nThis dataset has been provided to the BA Programme on the condition that third parties may not reproduce this dataset. Third parties wishing to use or reproduce this data should contact the data provider.\n\n## **Purpose** \n\nData Status:\n\nThis is a preliminary dataset, the project is on going.\n\n## **Dataset History** \n\nVegetation in NSW of high ecological value having high probability of being groundwater dependent were identified through a process that used current vegetation data, depth to groundwater data, data that showed potential frequency of water use other than surface water based on a continuous 10 year period and expert opinion. High Probability vegetation communities were identified as being of High Ecological Value when they sat within one or more selected datasets. (see below)\n\n\n\nGeographic Extent: Northern Rivers CMA\n\nData sources:\n\n\n\nHigh Probability\n\n1. Vegetation: obtained from OEH\n\n2. Depth to groundwater: modelled data provided by Office of Water Hydrogeologists\n\n3. Potential frequency of water use other than surface water based on a continuous 10\n\nyear period : This data set was created by Herbert Hemakumara (Office of Water) using\n\nremote sensing MODIS\n\n\n\nHigh Ecological Value\n\n1. National Parks and State Forests (OEH)\n\n2. SEPP 14 & 26 (Dept Planning)\n\n3. RAMSAR Wetlands (OEH)\n\n4. Marine parks and aquatic reserves (OEH)\n\n5. Identified rain forest communities (OEH)\n\n6. Threatened or endangered species (OEH)\n\n7. Wildlife corridors, Regional Conservation strategies or communities identified as\n\nbeing significant in various studies (Various Sources)\n\nPositional Accuracy:\n\nThe eastings and northings of all points are only approximate.\n\nThe shape of polygon features are only approximate.\n\n\n\nData Status:\n\nThis is a preliminary dataset, the project is on going.\n\n## **Dataset Citation** \n\nNSW Office of Water (2015) Northern Rivers CMA GDEs (DRAFT DPI pre-release).

本数据集包含覆盖北河集水区管理局（Northern Rivers CMA）辖区内地下水依赖生态系统（Groundwater Dependant Ecosystems）的多边形ESRI形状文件（ESRI shapefile），为DPI预发布草稿版本。

本数据集向生物区域评估计划提供时附带使用限制：第三方不得复制本数据集。第三方如需使用或复制该数据，请联系数据提供方。

## 用途
数据状态说明：
本数据集属于初步成果，相关项目仍在推进中。

## 数据集历史
本数据集通过多源数据结合专家意见的方式识别出新南威尔士州（NSW）内具有高生态价值且极有可能依赖地下水的植被：采用现有植被数据、地下水埋深数据、基于连续10年监测周期的非地表水潜在用水频次数据，结合专家研判完成识别。当高概率依赖地下水的植被群落落入一个或多个指定数据集范围时，即被认定为高生态价值植被群落（详见下文）。

地理覆盖范围：北河集水区管理局（Northern Rivers CMA）辖区

数据来源：

高概率依赖地下水植被
1. 植被数据：由环境与遗产局（Office of Environment and Heritage, 简称OEH）提供
2. 地下水埋深数据：由水务局水文地质学家办公室（Office of Water Hydrogeologists）提供的建模数据
3. 基于连续10年监测周期的非地表水潜在用水频次数据：该数据集由水务局（Office of Water）的Herbert Hemakumara利用MODIS遥感数据制作完成。

高生态价值植被群落
1. 国家公园与州立森林（OEH）
2. 新南威尔士州环境规划政策14与26（SEPP 14 & 26，规划部提供）
3. 拉姆萨尔公约湿地（RAMSAR Wetlands，OEH）
4. 海洋公园与水生保护区（OEH）
5. 已认定的雨林群落（OEH）
6. 受威胁或濒危物种栖息地（OEH）
7. 野生动物廊道、区域保护策略或各类研究中认定具有重要意义的植被群落（多源数据）

位置精度说明：
所有点位的东向与北向坐标仅为近似值；
多边形要素的轮廓仅为近似形态。

数据状态说明：
本数据集属于初步成果，相关项目仍在推进中。
