Climate Change Corridors (Dry Habitat) for North East NSW

## **Abstract** \n\nThis dataset and its metadata statement were supplied to the Bioregional Assessment Programme by a third party and are presented here as originally supplied.\n\n\n\nThe data integrates best available information to delineate broad wildlife corridors, for fauna occupying dry habitat, along climatic gradients. The objective of the layer is to best delineate large-scale wildlife corridors that are significant for wildlife adaptation to the threatening processes of climate change. The work has been based on key habitat habitats (Scotts, 2003), vegetation mapping layers and NSW Wildlife Atlas and YETI databases to represent areas of the landscape that contain high conservation values and high fauna corridor values.\n\n## **Purpose** \n\nThis project was commissioned by the Conservation Partnerships, Parks and Wildlife Division to identify land areas to develop a strategic approach to the establishment of protected areas on private and other public lands that complements the public reserve system and enhances the CAR design principles such as representation, adequacy and comprehensiveness. The strategy will be based on improving connectivity to address potential impact of climate change. The identification of wildlife corridors for climate change will contribute to the conservation and protection of landscape scale climate change corridors. The project has strong links to the recently announced "Alps to Atherton" (A to A) Climate Change Corridor and is essentially a finer scale interpretation of the A to A concept and function at a regional scale.\n\n## **Dataset History** \n\nThe Climate Change Corridors layer was primarily delineated by using a visual assessment of the landscape based on the spatial mapping of dry fauna assemblage corridors as derived by the existing Key Habitats and Corridors for forest fauna (Scotts, 2003). Fauna assemblages were grouped together to best represent general climatic corridors significant for dry habitat assemblages. The initial design was then refined and analysed using DEC vegetation mapping layers:- Northern Rivers CMA mapping (Ecological ,2005), Forest Ecosystem Mapping (NPWS, 1999) NSW Atlas records, YETI database and visual checking using SPOT5 (2005) satellite imagery. This stage of the project refined the boundaries of the broad corridors and assessed the significance of the corridors for forest fauna that were considered vulnerable to climate change effects. A process of expert review was carried out on the first output from the process with consideration of projected climate change effects.\n\n\n\nExplanation \tThe product is based on existing desk top data (best available). No ground truthing of the attributes has been carried out. Much of the information is derived through analysis of existing data products and expert review of those products and decision making. Therefore it is likely that some area may be subject to review if adequate field checking were to be made. The data represents a regional scale assessment of landscapes in terms of their benefit to wildlife ecology and landscape connectivity.\n\n## **Dataset Citation** \n\nNSW Office of Environment and Heritage (2011) Climate Change Corridors (Dry Habitat) for North East NSW.

**摘要**

本数据集及其元数据声明由第三方提交给生物区域评估计划（Bioregional Assessment Programme），此处按原始提交版本完整呈现。

该数据集整合现有最优信息，沿气候梯度划定适用于干旱生境野生动物的大型野生动物廊道。本图层的制作目标是精准界定对野生动物适应气候变化威胁过程具有关键意义的大规模野生动物廊道。本研究依托关键栖息地（斯科茨，2003）、植被绘图图层、新南威尔士州野生动物图集（NSW Wildlife Atlas）及YETI数据库（YETI），以表征景观中兼具高保护价值与高野生动物廊道价值的区域。

**用途**

本项目由保护伙伴关系、公园与野生动物分部委托开展，旨在识别适宜区域，制定战略方案以在私人及其他公共土地上建立保护区，补充现有公共保护地体系，并强化CAR（代表、充足与全面）设计原则。该战略将以提升景观连通性为核心，应对气候变化带来的潜在影响。为气候变化适配划定野生动物廊道，将有助于保护与维护景观尺度的气候变化廊道。本项目与新近公布的“阿尔卑斯至阿瑟顿”（Alps to Atherton，简称A到A）气候变化廊道项目关联紧密，本质上是对A到A概念与功能在区域尺度上的精细化阐释。

**数据集历史**

气候变化廊道图层最初通过视觉评估景观完成划定，其依据为现有森林野生动物关键栖息地与廊道（斯科茨，2003）所推导的干旱生境动物群落廊道的空间制图成果。研究团队将动物群落进行整合分类，以最优表征干旱生境群落所依赖的关键气候廊道。随后，本项目依托新南威尔士州环境与遗产办公室（DEC）的植被绘图图层开展优化与分析：包括北河地区海岸管理局（Northern Rivers CMA）绘图（生态，2005）、森林生态系统绘图（国家公园与野生动物服务局，1999）、新南威尔士州图集记录、YETI数据库（YETI），并通过SPOT5卫星影像（SPOT5）进行目视校验。本阶段细化了大型廊道的边界，并评估了受气候变化影响的脆弱森林野生动物所依赖的廊道的重要性。研究团队针对项目首轮产出成果开展专家评审，并结合气候变化的预估影响进行了综合考量。

**说明**

本产品基于现有桌面端公开数据（即当前可获取的最优数据），未对数据集属性开展实地验证。多数信息通过分析现有数据产品、开展专家评审及决策推导得出。因此，若开展充分的野外校验工作，部分区域的划定结果可能需要进行调整。本数据集从野生动物生态学与景观连通性的视角，对研究区域开展了区域尺度的评估。
