England Woodland Creation Low Sensitivity Map v3.0: variant 3

The Forestry Commission has developed a series of sensitivity maps, based on nationally available and consistent datasets, to indicate where there are likely to be fewer sensitivities to woodland creation. These maps will help to indicate to landowners whether there is likely to be potential to establish new woodland on their land, and where there may be sensitivities that would preclude woodland creation. The maps do not indicate that, where there is a low sensitivity to new woodland being created, that planting will be agreed by the Forestry Commission, the regulator for woodland and forestry projects in England. However, the low sensitivity areas have fewest identified constraints to address, and it should be easier to agree creating new woodland here than in other areas. Likewise, creation of new woodland, particularly of native woodland, may be appropriate outside ‘low sensitivity’ areas, but the appropriateness of proposals in these areas will again be determined by the Forestry Commission, including through responding to the views of Natural England, Environment Agency, Historic England, the Local Authority and other stakeholders, where relevant. The Sensitivity Maps exclude all land that is unsuitable for planting, including urban areas, existing (and assumed) woodland and habitats that are considered too wet, too rocky, and too salty to support the growth of trees. This is achieved through restricting the Sensitivity Maps to the following land covers, based on the most recent update of Landcover Map: Acid grassland Arable and horticulture Calcareous grassland Heather Heather grassland Improved grassland Neutral grassland The spatial datasets and individual layers of those datasets that define land as unsuitable and low, medium, or high sensitivity for woodland creation in the Full Sensitivity Map version 3.0, the Low Sensitivity Map and their variants are set out in the document here: www.gov.uk/guidance/a-guide-to-forestry-commissions-sensitivity-maps-for-woodland-creation Attributes: ‘Sensitivity’ = the sensitivity to woodland creation level the land has been assigned. ‘Area (Hectares)’ = the area in hectares of the polygon. Lineage: This is version 3.0 of these layers, having gone through several iterations where new data inputs were added and changes made to how these were treated as sensitivities for woodland creation. These are the first versions of the layers to be published as Open Data.英国林业委员会（Forestry Commission）基于全国可获取且统一的数据集，开发了一系列敏感性地图，用以标识出对营造林地而言敏感性较低的区域。 此类地图可帮助土地所有者判断其地块是否具备营造新林地的潜在可能，以及哪些区域存在可能阻碍林地营造的敏感性因素。 需注意，即便某区域对新建林地的敏感性较低，也不代表英国林业委员会——英格兰林地与林业项目的监管机构——会批准在此开展种植活动。不过低敏感性区域已识别的约束条件最少，相较于其他区域，在此处申请营造新林地通常会更为容易。 同理，在“低敏感性”区域之外也可能适宜营造新林地，尤其是乡土林地，但此类区域的营造提案是否可行，仍需由英国林业委员会判定，其中包括参考自然英格兰（Natural England）、环境署（Environment Agency）、历史英格兰（Historic England）、地方当局及其他相关利益相关方的意见。 敏感性地图已排除所有不适宜植树的土地，其中涵盖城市区域、现有（及推定存在的）林地，以及被认为过于潮湿、多石或盐碱度过高而无法支撑树木生长的生境。此类筛选通过将敏感性地图限定于最新版《土地覆盖地图》（Landcover Map）所定义的以下土地覆盖类型实现： 酸性草地 耕地与园艺用地 钙质草地 欧石楠 欧石楠草原 改良草地 中性草地 完整版敏感性地图3.0、低敏感性地图及其变体中，用于定义土地不适宜、低、中或高敏感性林地营造等级的空间数据集及各数据图层，已在以下文档中列明： www.gov.uk/guidance/a-guide-to-forestry-commissions-sensitivity-maps-for-woodland-creation 属性说明： “敏感性”：指该地块被赋予的林地营造敏感性等级。 “面积（公顷）”：指该多边形地块的面积，单位为公顷。 数据谱系： 本系列图层为3.0版本，此前历经多次迭代，新增了数据输入项并调整了林地营造敏感性的判定方式。此为首次以开放数据（Open Data）形式发布的图层版本。
