NSW - CRA/RFA - Forests - Eden - National Estate - Undisturbed Catchments

Undisturbed catchment data was developed to satisfy National Estate assessment of extensive natural values under the comprehensive regional assessment (CRA) of the Eden region. \n\nThe identification of undisturbed catchments was based on an analysis of river flow impediments and the naturalness of the area within the catchment. This assessment is derived from the River Disturbance Index (RDI) Database (Stein 1995) created by the Wilderness and Wild Rivers Section, Australian Heritage Commission.\n\nUndisturbed catchments was derived by applying a threshold to the RDI to extract catchments with minimal disturbance.\n\nThis dataset has been assessed against the following National Estate sub-criterion: B1: Importance for rare, endangered or uncommon flora, fauna, communities, ecosystems, natural landscapes or phenomena, or as a wilderness.\n\nThis is an archived dataset jointly owned by the Commonwealth Government and NSW Governments under the NSW Regional Forest Agreements (RFA) Data Agreement of 31 March 2000.This data is available to the public from the Department and may be used by third parties for unrestricted use provided that the copyright interests of the owners are protected.\n\nAny reproduction of this dataset must carry the following statement:\nCopyright Commonwealth of Australia and New South Wales Government 1997.\nDepartmental Deed

本未受干扰流域数据集（Undisturbed catchment data）旨在配合伊登地区综合区域评估（Comprehensive Regional Assessment, CRA）框架下的国家遗产（National Estate）评估工作，以满足该区域广泛自然价值的评估需求而编制。

未受干扰流域的识别，基于对流域内河流径流阻碍因素与区域自然性的分析。本次评估依据由澳大利亚遗产委员会（Australian Heritage Commission）荒野与野生河流部门编制的《河流干扰指数（River Disturbance Index, RDI）数据库（Stein, 1995）》。

本未受干扰流域数据集通过为RDI设置阈值，提取受干扰程度最低的流域，进而生成。

本数据集已依据以下国家遗产子标准B1完成评估：B1项指对于珍稀、濒危或罕见的动植物、群落、生态系统、自然景观或自然现象的重要价值，或作为荒野区域的重要性。

本数据集为存档数据集，由澳大利亚联邦政府（Commonwealth Government）与新南威尔士州政府（New South Wales Government, NSW）共同所有，依据2000年3月31日签署的《新南威尔士州区域森林协议（Regional Forest Agreements, RFA）数据协定》。该数据集可通过相关部门向公众开放，第三方可在保障版权所有者合法权益的前提下，无限制使用本数据。
