Sustainably Managed Woodland England - Headline Key Performance Indicator 30 September 2024

Attributes: CLASS = managed status. Managed status descriptions: 'Managed private' = any woodland where management is indicated by an administrative data source – see lineage for more information. 'Managed public' = any of our nation’s forests managed by Forestry England. Lineage: Measurement Methodology - Headline indicator A. This actual formal headline KPI: Percentage of woodland that is sustainably managed in England (including the nation's forests managed by Forestry England). This is expressed as a percentage of all National Forest Inventory (NFI) woodland in the latest available NFI woodland map at the time of computations for the respective reports. B. Sub-indicator: Percentage of woodland that is sustainably managed in England other than in the nation's forests managed by Forestry England. As for the main formal indicator above, minus contribution 1. in the nation's forests managed by Forestry England. This is expressed as a percentage of all National Forest Inventory (NFI) woodland in the nation's forests managed by Forestry England, in the latest available NFI woodland map at the time of computations for the respective reports. Numerator: Woodland is counted as in sustainable management where the woodland is included in any one or more of the following categories: 1. In the nation's forests managed by Forestry England (aka ‘Public Forest Estate’), 2. England Woodland Grant Scheme (EWGS) Woodland Creation Grant, where the contract start date is within 15 years before the report date, 3. EWGS Woodland Management Grant, where the contract start date is within 15 years before the report date, 4. EWGS Woodland Planning Grant, where the contract start date is within 15 years before the report date, 5. EWGS Woodland Improvement Grant, where the contract start date is within 15 years before the report date, 6. Woodland Grant Scheme 3, where the contract start date is within 15 years before the report date, 7. Farm Woodland Premium Scheme, where the contract start date is within 15 years before the report date, 8. Is covered by a Felling Licence Application, where the contract start date is within 15 years before the report date, 9. Is covered by Management Plans, where either funded or unfunded, and approved within the 10 years before the report date, 10. Is woodland on a Defence Infrastructure Organisation (DIO) training area, 11. Countryside Stewardship woodland creation, where claims were paid before the report date, 12. Countryside Stewardship restocking, where the contract start date is within 2 years 3 months before the report date, 13. Statutory Plant Health Notices (SPHN). Denominator: Woodland is defined as National Forest Inventory (NFI) woodland in the most up to date NFI map available. Formula: The percentage of woodland in sustainable management in England equals a) the area of woodland in sustainable management in England (hectares) divided by b) the area all National Forest Inventory woodland in the NFI map in England (hectares) c) * 100.属性字段为**管理状态（managed status）**。管理状态说明如下： 1. 受管理私有林地（Managed private）：指通过行政数据源标识存在管理行为的全部林地，详细信息请参阅数据溯源（lineage）部分。 2. 受管理公共林地（Managed public）：指由英格兰林业署（Forestry England）管理的英格兰国家森林。 ### 数据溯源（Lineage） A. 测算方法论——核心指标：正式核心关键绩效指标（KPI）为：英格兰境内可持续管理林地占比（含英格兰林业署管理的国家森林）。该占比以对应报告编制当期所用的最新版国家森林普查（National Forest Inventory, NFI）林地地图中，英格兰全境NFI林地总面积为基数计算得出。 B. 子指标：英格兰境内除英格兰林业署管理的国家森林外，可持续管理林地占比。计算方式为上述正式核心指标减去英格兰林业署管理的国家森林的贡献值，以对应报告编制当期最新版NFI林地地图中，英格兰林业署管理的国家森林内全部NFI林地总面积为基数计算得出。 ### 分子（Numerator） 符合以下任意一项或多项类别的林地，将被计入可持续管理林地范畴： 1. 英格兰林业署管理的国家森林（又称“公共森林资产（Public Forest Estate）”）； 2. 英格兰林地拨款计划（England Woodland Grant Scheme, EWGS）林地创建拨款，且合同启动日期距报告日期不超过15年； 3. EWGS林地管理拨款，且合同启动日期距报告日期不超过15年； 4. EWGS林地规划拨款，且合同启动日期距报告日期不超过15年； 5. EWGS林地改良拨款，且合同启动日期距报告日期不超过15年； 6. 林地拨款计划3（Woodland Grant Scheme 3），且合同启动日期距报告日期不超过15年； 7. 农场林地溢价计划（Farm Woodland Premium Scheme），且合同启动日期距报告日期不超过15年； 8. 持有采伐许可申请（Felling Licence Application），且合同启动日期距报告日期不超过15年； 9. 纳入管理计划（无论是否获得资助），且该计划于报告日期前10年内获批； 10. 位于国防基础设施组织（Defence Infrastructure Organisation, DIO）训练区内的林地； 11. 乡村保育计划（Countryside Stewardship）林地创建项目，且已在报告日期前获得赔付； 12. 乡村保育计划补植项目，且合同启动日期距报告日期不超过2年3个月； 13. 法定植物健康通告（Statutory Plant Health Notices, SPHN）覆盖的林地。 ### 分母（Denominator） 统计范围为当期可用的最新版NFI林地地图中，英格兰境内的全部NFI林地。 ### 计算公式 英格兰境内可持续管理林地占比 = （a）英格兰境内可持续管理林地面积（单位：公顷） ÷ （b）当期最新版NFI林地地图中，英格兰境内全部NFI林地总面积（单位：公顷） × 100。
