EWCO - Keeping Rivers Cool Riparian Buffers

Spatial data supporting appropriately located and designed woodland creation where this will provide dappled shade to improve aquatic ecology by reducing summer water temperatures and benefiting wildlife dispersal (for example, otter) along the corridors of habitat this creates. The data represents a 50 m buffer around patches of surface waterbodies (rivers) with little or no existing riparian shade. Sections of river with the least amount of shading from riparian vegetation are considered to be priority areas for tree planting and therefore candidates for incentives such as additional grant aid to encourage woodland creation to provide greater shading in the future. Data input sources: Relative riparian shade map (Environment Agency) National LIDAR Programme Vegetation Object Model (Environment Agency) Attributes: ‘AreaHa’ – Area of the feature in hectares. Lineage: First published to support the woodland creation grant under Countryside Stewardship (CS), launched in 2015. The layer methodology was then revised by Forest Research and the layer was updated in 2022/23 to cater for the new England Woodland Creation Offer (EWCO) scheme. A detailed methodology describing the development of this layer can be requested from [e-mail].本空间数据可支撑选址与设计合理的林地营造项目：此类项目可通过营造斑驳遮阴效果降低夏季水体温度，从而改善水生生态，并通过所营造的生境廊道助力野生动物（如水獭）的扩散活动。 本数据以现有河岸植被遮阴极少或完全缺失的地表水体（河流）斑块为对象，生成其50米缓冲范围图层。河岸植被遮阴程度最低的河段被认定为植树造林的优先区域，因此可纳入激励政策适用范围，例如通过额外拨款资助鼓励后续林地营造，以提升未来的水体遮阴效果。 数据输入来源：相对河岸遮阴度图（环境署，Environment Agency）、国家激光雷达（LIDAR）计划植被对象模型（环境署，Environment Agency） 属性字段：‘AreaHa’——以公顷为单位的要素面积。 数据沿革：本数据集最初于2015年发布，用于支持《乡村管理计划（Countryside Stewardship, CS）》下的林地营造补贴项目。后由林业研究所（Forest Research）修订图层制作方法，并于2022/2023年更新图层，以适配新版英格兰林地营造资助计划（England Woodland Creation Offer, EWCO）。 如需获取本图层开发的详细方法文档，可致信[e-mail]申请。
