Fauna Corridors

Data quality Lineage: The process employed in deriving fauna corridors is explicit and repeatable in as much as: * The fauna species models, which are the basic biodiversity entities that the project seeks to summarise and integrate are stored and held by NPWS; * All relevant data layers, developed at each stage of the project, are stored and held by NPWS; * The Geographic Information System (GIS) tools developed for the analyses are available as extensions to the ARCVIEW GIS. At numerous stages of the analyses, informed interpretation of outputs and assignment of thresholds has been required to move the process along or to finalise an output. Any qualitative decisions taken have been based on the project manager's ecological expertise and knowledge of the data sets being considered. Habitat corridors have been mapped across public and private lands. The process of deriving and mapping regional corridors for fauna has involved the use of fauna assemblage distributions and fauna key habitats (see additional metadata referenced below), as surrogates for areas of high fauna conservation, and as the actual habitats to be linked. For more detailed information about lineage see http://www.bionet.nsw.gov.au/website/keyhabs Positional accuracy: Species assemblage distributions, key habitats and corridors have been derived from interpolated species distributions generated by modelling point locality species records (with a spatial accuracy of approximately 100m) in relation to mapped environmental layers (with a map scale of 1:100 000 to 1:250 000) (see additional metadata). The CORRIDORS analysis was undertaken at the 500m grid cell size in order to reduce computational burden. The outputs were re-sampled to 100m grid cell for display and storage. In applying and interpreting the key habitats map layer it should always be remembered that they are based on modelled data and have been developed at the regional scale, to inform regional land, water and vegetation reform programs. The mapped products represent a state-of-the-art consolidation of fauna information for UNE and LNE areas but should be interpreted in terms of a likelihood of occurrence of fauna key habitats; they are indicative representations (see mapping caveat). It should also be noted that the process of development of the key habitats layer has necessarily included qualitative judgements relating to interpretations and setting of thresholds; these have been made based on ecological expertise and explicit decision rules.数据质量溯源（Data quality Lineage）：野生动物廊道（fauna corridors）的生成流程具备明确性与可复现性，具体依据如下： * 本项目旨在汇总与整合的核心生物多样性实体——野生动物物种模型，由NPWS存储与保管； * 项目各阶段生成的所有相关数据图层，均由NPWS存储与保管； * 为本次分析开发的地理信息系统（GIS）工具，可作为ARCVIEW GIS的扩展插件使用。 在分析的诸多环节中，需对输出结果进行专业解读，并设定阈值以推进流程或完成最终输出。所有定性决策均基于项目经理的生态学专业知识以及对所涉数据集的了解。 野生动物栖息地廊道已在公共与私有土地上完成制图。野生动物区域廊道的生成与制图流程，以野生动物群落分布与野生动物关键栖息地（详见下文提及的附加元数据）作为高野生动物保护价值区域的替代指标，以及需连通的实际栖息地。如需了解溯源流程的详细信息，请访问：http://www.bionet.nsw.gov.au/website/keyhabs 位置精度（Positional accuracy）： 野生动物群落分布、关键栖息地与廊道的数据，源自基于物种点位记录建模得到的插值物种分布：该建模以空间精度约100米的物种点位记录为基础，结合比例尺为1:100000至1:250000的已制图环境图层（详见附加元数据）。 为降低计算负荷，"CORRIDORS"分析采用500米的网格单元尺寸开展。为便于展示与存储，分析结果被重采样至100米的网格单元。 在使用与解读关键栖息地图层时，需始终注意：该图层基于建模数据生成，且以区域尺度开发，旨在为区域土地、水资源与植被改革项目提供参考。本次制图成果整合了UNE与LNE区域内的野生动物相关信息，代表了当前该领域的顶尖水平，但需结合野生动物关键栖息地的发生概率进行解读，仅为示意性成果（详见制图免责声明）。 此外需说明，关键栖息地图层的开发过程必然包含与解读及阈值设定相关的定性判断，此类判断均基于生态学专业知识与明确的决策规则制定。
