Biodiversity Conservation Lands for the Lower Hunter Regional Strategy

The Biodiversity Conservation Lands dataset has been compiled for the Lower Hunter and interpreted as presenting planning constraints at three scales;\r\n\r\n* State: Areas identified as of state significance in recognition of a related state or federal conservation policy or program;\r\n* Regional : Areas identified as of regional significance generally in recognition of a related state policy or program or as providing buffers to state significant lands;\r\n* Local : Areas recognised through local conservation zoning and including all remnant vegetation.\r\n\r\nPrinciples for deriving conservation constraints:\r\n\r\n1. A twenty five-year planning horizon was adopted for identifying Biodiversity Conservation Lands and opportunities.\r\n2. State, regional and local significance classes for conservation constraints were adopted and spatially delineated.\r\n3. Biodiversity features are presented as constraints with limited or no transferability. Irreplaceability of significant features is generally low and in situ conservation is generally required. The level of irreplaceability for each feature is noted in the metadata proformas.\r\n4. Biodiversity Conservation Lands will generally be identified across the landscape regardless of current tenure or zoning. Whilst back-zoning of existing development zones is not envisaged, protection of high conservation value features occurring in existing development zones will be encouraged.\r\n\r\nThe Biodiversity Conservation Lands is complete for all Local Government Areas along the coast from Tweed Heads to Gosford. This metadata statement deals with that portion of the data covering the Local Government Areas of Newcastle, Lake Macquarie, Port Stephens, Maitland and Cessnock.\r\n\r\nThere are two BioConLands datasets for each Regional Strategy area - a simplified one containing only State, Regional and Local categories in the attribute table and a larger, more complex version with "detailed" information on the components that went into the datasets.\r\n\r\n__Note:__ Certain boundaries within these datasets, eg. NPWS and State Forest Estate, are only current to 2007.本生物多样性保护用地（Biodiversity Conservation Lands）数据集为下亨特地区（Lower Hunter）编制，其被解读为在三个尺度上呈现规划约束条件： * 州级：依据相关州级或联邦保护政策、项目认定的具有州级重要性的区域； * 区域级：通常依据相关州级政策、项目认定，或作为州级重要用地的缓冲带而被界定为具有区域重要性的区域； * 地方级：通过地方保护分区划定的区域，包含所有残存植被。 保护约束条件的衍生原则： 1. 在识别生物多样性保护用地及保护机遇时，采用了25年的规划时限； 2. 确立了保护约束条件的州级、区域级、地方级重要性分级体系，并完成了空间划定； 3. 生物多样性要素以约束条件形式呈现，其可迁移性有限或完全不具备。重要生物多样性要素的不可替代性通常较低，通常需开展原位保护。各要素的不可替代性等级将在元数据标准模板中注明； 4. 生物多样性保护用地的划定通常覆盖全域景观，不受当前土地权属或分区的限制。尽管未计划对现有开发区域实施反向分区调整，但仍将鼓励对现存开发区内的高保护价值生物多样性要素开展保护工作。 本生物多样性保护用地数据集已覆盖从特威德角（Tweed Heads）至戈斯福德（Gosford）沿岸的所有地方政府区域。本次元数据说明仅针对其中涵盖纽卡斯尔（Newcastle）、麦夸里湖（Lake Macquarie）、斯蒂芬斯港（Port Stephens）、梅特兰（Maitland）以及塞斯诺克（Cessnock）的地方政府区域部分。 每个区域战略区域均配套两套BioConLands（生物多样性保护用地）数据集：一套为简化版，属性表中仅包含州级、区域级、地方级三类分级；另一套为更庞大复杂的版本，包含构成该数据集的各组分的"详细"信息。 注意：本数据集内的部分边界（例如国家公园与野生动物服务局（NPWS）管辖区域及州立森林用地）的现势性仅截至2007年。
