High Ecological Value Waterways and Water Dependent Ecosystems - BURWOOD LGA

A map of the high ecological value waterways and water dependent ecosystems for the Burwood LGA was prepared by the Science Division of the Department of Planning, Industry and Environment, with input layers and support for the map provided by the former NSW Department of Primary Industries-Fisheries and Department of Industry-Crown Lands and Water. The basis for the map arises from Science Division inputs to strategic planning processes. For example, the map has been included in the Land Use and Infrastructure Implementation Plans for the Wilton (Wilton2040, page 22) and Greater Macarthur (interim plan, page 36) Priority Growth Areas. This map was specifically developed for input to Local Government Local Strategic Planning Statements to support Council’s delivery of Strategy 25.1 of the Greater Sydney Region Plan.\r\n\r\nThe map shows areas where waterways and water dependent ecosystems are defined as high ecological value, based on definitions, guidelines and policies under the Environment Protection and Biodiversity Conservation Act 1999, Biodiversity Conservation Act 2016, Fisheries Management Act 1994 and Water Management Act 2000. Water dependent ecosystems are defined as wetlands, and flora and fauna that rely on water sources (including groundwater). The map represents an overlay of 39 indicators being used by the State Government to define high value, however, not all 39 indicators will be present in any one LGA (see Attachment 1 below). For example, there are 3 indicators making up the map for the Burwood LGA. It should also be noted that the individual indicators have not been ground-truthed and it is recommended that field assessments and/or a comparison to local mapping be undertaken prior to any decisions being made.\r\nThe map was created by initially placing a 1 ha (to correspond with a lot size) hexagon grid over the LGA, and attributing the grid with the area, length and/or frequency of occurrence of high value water dependent ecosystems. The purpose of the map is to identify strategic planning priorities for protecting and improving the health of high value waterways and water dependent ecosystems in the LGA. Once identified, the priorities can be used as a basis for identifying aquatic biodiversity refugia, stream rehabilitation efforts and setting management targets and/or land use planning controls that would protect or improve the health of waterways and water dependent ecosystems so they provide the essential services and functions expected of a cool blue-green corridor.

Burwood地方政府区域（Local Government Area, LGA）高生态价值水道及水依赖型生态系统分布图由规划、工业与环境部科学处编制，地图的输入图层及技术支持由前新南威尔士州初级产业部-渔业局与工业部-皇冠土地及水资源局提供。该地图的编制依据源于科学处对战略规划流程的输入成果。例如，其已被纳入Wilton（Wilton2040，第22页）及大Macarthur（临时规划，第36页）重点增长区的土地利用与基础设施实施规划中。此地图专为地方政府区域战略规划声明提供输入而开发，以支持议会落实《大悉尼区域规划》第25.1战略。

该地图基于《1999年环境保护与生物多样性保护法案》《2016年生物多样性保护法案》《1994年渔业管理法案》及《2000年水资源管理法案》中的定义、指南与政策，标识出具有高生态价值的水道及水依赖型生态系统区域。水依赖型生态系统指湿地，以及依赖水源（含地下水）生存的动植物群落。该地图是州政府用于界定高价值区域的39项指标的叠加呈现；不过，并非所有39项指标均适用于单一地方政府区域（LGA）（详见下文附件1）。例如，Burwood LGA的地图仅包含其中3项指标。需注意的是，各项指标尚未经过实地验证，因此建议在做出任何决策前开展实地评估及/或与地方地图进行比对。
该地图的制作流程如下：首先在地方政府区域（LGA）范围内布设1公顷（与地块面积对应）的六边形网格，随后为每个网格赋予高价值水依赖型生态系统的面积、长度及/或出现频率属性。该地图的目的在于明确地方政府区域内保护与改善高价值水道及水依赖型生态系统健康状况的战略规划重点。一旦确定这些重点，即可将其作为识别水生生物多样性避难所、开展溪流修复工作、设定管理目标及/或制定土地利用规划管控措施的依据，从而保护或改善水道及水依赖型生态系统的健康状况，使其发挥凉爽蓝绿廊道应有的核心服务功能。
