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.

生物多样性保护地数据集（Biodiversity Conservation Lands dataset）针对下亨特地区（Lower Hunter）编制，旨在从三个尺度呈现规划约束条件；

* 州级：因符合相关州或联邦保护政策或计划而被认定为具有州级重要性的区域；
* 区域级：因符合相关州政策或计划、或为州级重要区域提供缓冲而被认定为具有区域级重要性的区域；
* 地方级：通过地方保护区划认定的区域，包括所有残余植被。

生物多样性保护约束条件的推导原则：

1. 确定生物多样性保护地及相关机遇时采用25年规划期。
2. 采用州级、区域级和地方级重要性类别，并对其进行空间划定。
3. 生物多样性特征作为约束条件呈现，其可转移性有限或不可转移。重要特征的不可替代性总体较低，通常需要就地保护。每个特征的不可替代性水平在元数据表格中注明。
4. 生物多样性保护地的识别通常不受现有权属或区划的限制。虽然不考虑对现有开发区进行回溯区划，但鼓励保护现有开发区内的高保护价值特征。

该生物多样性保护地数据集已覆盖从特威德黑德（Tweed Heads）到戈斯福德（Gosford）沿海的所有地方政府辖区。本元数据声明涉及数据中覆盖纽卡斯尔（Newcastle）、麦夸里湖（Lake Macquarie）、斯蒂芬斯港（Port Stephens）、梅特兰（Maitland）和塞斯诺克（Cessnock）地方政府辖区的部分。

每个区域战略区域对应两个BioConLands数据集——一个简化版，其属性表仅包含州级、区域级和地方级类别；另一个更复杂的版本，则包含数据集各组成部分的"详细"信息。
