Biodiversity Conservation Lands for the Upper Hunter Regional Strategy

The Biodiversity Conservation Lands dataset has been compiled for the Upper 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 Gloucester and Dungog.\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数据集（Biodiversity Conservation Lands）针对上亨特地区编制，其被解读为三类尺度下的规划约束要素：

* 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：依据相关州级政策/项目认定的具有区域重要性的区域，或作为州级重要用地的缓冲带的区域；
* 本地级：通过本地保护分区认定的区域，包含所有残存植被。

生物多样性保护用地规划约束的制定原则如下：

1. 本次生物多样性保护用地及保护机遇的识别采用25年规划时限；
2. 采用州级、区域级、本地级三级保护约束重要性分级，并完成空间划定；
3. 生物多样性特征以约束要素形式呈现，其可迁移性极低或完全不可迁移。重要保护特征的不可替代性普遍较低，通常需开展原位保护。各保护特征的不可替代等级将在元数据格式表中注明；
4. 生物多样性保护用地的识别通常覆盖全域景观，不考虑当前土地保有形式或分区情况。尽管不计划对现有开发区进行反向分区调整，但将鼓励对现有开发区内的高保护价值特征开展保护工作。

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辖区。本次元数据说明仅针对数据集覆盖格洛斯特（Gloucester）与邓古格（Dungog）地方政府辖区的部分内容。

每个区域战略区域对应两套BioConLands数据集：一套为简化版，属性表中仅包含州级、区域级、本地级三类分类；另一套为内容更丰富的复杂版本，包含构成该数据集的各组分的"detailed"信息。
