FGS Climatic Site Suitability - Broadleaves

Woodland Creation forms part of the Scottish Rural Development Programme (SRDP) 2014 - 2020. The SRDP delivers Pillar 2 of the EU Common Agricultural Policy (CAP). Utilising some £1,326m of European Agricultural Fund for Rural Development funding, plus Scottish Government match funding, it funds economic, environmental and social measures for the benefit of rural Scotland. The SRDP is co-funded by the European Commission and the Scottish Government and reflects the 6 EU Rural Development Priorities. The programme also reflects the Scottish Government National Policy Framework (NPF).

The aim of the Forestry Grant Scheme woodland creation category is to support the creation of new woodlands that will provide a range of economic, environmental and social benefits which include:
- delivery of the Scottish Government target to extend woodland cover by an additional 100,000 hectares over the period of 2012-2022
- climate change mitigation by tackling greenhouse gas emissions through carbon sequestration
- restoration of lost habitats through developing forest habitat networks
- underpinning a sustainable forest industry by providing a reliable timber supply
- protecting the soil and water environment
- providing community benefits through public access
- enhancing urban areas and improving landscapes
- supporting rural development through local businesses and farm diversification

A fundamental consideration when creating new woodland is whether or not the tree species is appropriate to the site. You should carry out an appropriate site based assessment of soil and vegetation to match species choice with the particular site. Forestry Commission 'Ecological Site Classification' (ESC) decision support system helps guide forest managers and planners to select ecologically suited species to sites. ESC considers: windiness; temperature; moisture; continentality; soil moisture and soil nutrients. This helps to determine suitability of the chosen species to the site and identifies it as: poor; marginal; suitable or very suitable.

In order to be considered for SRDP grant support the overall suitability for your chosen species must be either 'very suitable' or 'suitable'.

As an initial first step in determining suitability, the polygons in this dataset represent the climatic suitability of the chosen tree species to the site. Climatic suitability, based on ESC uses the following climatic site factors:
- Accumulated temperature
- Moisture deficit
- Exposure (Detailed Aspect Method Scoring [DAMS])
- Continentality

NOTE: This datasets does NOT take into account any soils information.

Any application that is identified on the map as being either 'unsuitable' or 'marginal' may still be considered - but only if you clearly demonstrate that the site is 'suitable' for the chosen species of tree (for example where there is localised shelter in an otherwise exposed location).

The woodland creation category has nine options and the associated aims are:

- 'Conifer'
To create conifer woodlands on land that is suitable for timber production and that is accessible for timber transport (including links to suitable public roads). This option is principally aimed at planting Sitka spruce.

- 'Diverse Conifer'
To create conifer woodlands on land that is suitable for timber production and that is accessible for timber transport (including links to suitable public roads). This option is aimed at planting conifer species other than Sitka spruce.

- 'Broadleaves'
To create broadleaved woodlands on land that is suitable for sawn and prime timber and that is accessible for timber transport (including links to suitable public roads).

- 'Native Scots Pine'
To create or expand native pinewood priority habitat (NVC) W18

- 'Native Upland Birch'
The creation of native upland birch woodland of the National Vegetation Classification (NVC) W4: Downy Birch with Purple Moor Grass on shallow peaty soils.

- 'Native Broadleaves'
To create native broadleaved priority woodland habitats of the following National Vegetation Classification (NVC) types:
W6 Alder with Stinging Nettle
W7 Alder-Ash with Yellow Pimpernel
W8 Ash, Field maple with Stinging Nettle
W9 Ash, Rowan with Dogs Mercury
W10 Oak (penduculate) with Bluebell Hyacinth
W11 Oak (sessile), Downy Birch with Bluebell/wild Hyacinth
W16 Oak, Birch
W17 Oak (sessile), Downy Birch with Bilberry/Blaeberry

- 'Native Low Density Broadleaves'
To create specific native woodland or scrub habitats; including areas of ecotones for black grouse, treeline woodlands, juniper and other forms of scrub woodland and wood pasture systems. Normally associated with other woodland habitats in a transitional situation (eg. transition onto open hill: Black Grouse; Montane Scrub).

- 'Small or Farm Woodland'
To create small scale mixed broadleaved and conifer woodlands on farms and other rural land.

- 'Native Broadleaves in Northern & Western Isles'
To create native woodlands that contributes to the Orkney, Shetland or Western Isles woodland strategies.

苏格兰乡村发展计划（SRDP）2014-2020年部分包括林地创建。该计划旨在实施欧盟共同农业政策（CAP）的第二支柱。通过利用13.26亿英镑的欧洲乡村发展基金资金，以及苏格兰政府的配套资金，该计划旨在为苏格兰乡村的经济、环境和社交利益提供经济、环境和社交措施。SRDP由欧盟委员会和苏格兰政府共同资助，并反映了欧盟的六项乡村发展优先事项。该计划亦体现了苏格兰政府的国家政策框架（NPF）。

林业补助计划中林地创建类别的目标是支持新林地的创建，以提供一系列经济、环境和社交效益，包括：
- 实现苏格兰政府将林地覆盖面积在2012-2022年间增加10万公顷的目标
- 通过碳汇缓解气候变化，应对温室气体排放
- 通过发展森林生境网络恢复失去的生境
- 通过提供稳定的木材供应支撑可持续的林业产业
- 保护土壤和水环境
- 通过公共通道提供社区利益
- 提升城市区域并改善景观
- 通过地方企业和农业多样化促进乡村发展

创建新林地时，一个基本考虑因素是树木物种是否适合该地点。您应进行适当的基于地点的土壤和植被评估，以匹配物种选择与特定地点。林业委员会的‘生态地点分类’（ESC）决策支持系统有助于引导森林管理者及规划者选择适合特定地点的生态适宜物种。ESC考虑了：风力、温度、湿度、大陆性、土壤湿度和土壤养分。这有助于确定所选物种对地点的适宜性，并将其划分为：不适宜、边缘适宜、适宜或非常适宜。

为了获得SRDP补助支持，所选物种的总体适宜性必须是‘非常适宜’或‘适宜’。

本数据集作为确定适宜性的初步第一步，其多边形表示所选树物种对地点的气候适宜性。气候适宜性基于ESC，使用以下气候地点因素：
- 累积温度
- 湿度赤字
- 暴露（详细方位评分法 [DAMS]）
- 大陆性

注：本数据集不考虑任何土壤信息。

在地图上被标识为‘不适宜’或‘边缘适宜’的应用仍可被考虑，但前提是您明确证明该地点对所选树种‘适宜’（例如，在暴露地点的局部遮蔽处）。

林地创建类别包括九个选项及其相关目标：
- ‘针叶林’
在适宜木材生产和木材运输（包括通往适宜公共道路的连接）的土地上创建针叶林。此选项主要针对种植西雅图云杉。
- ‘多元针叶林’
在适宜木材生产和木材运输（包括通往适宜公共道路的连接）的土地上创建针叶林。此选项旨在种植除西雅图云杉外的针叶树种。
- ‘阔叶林’
在适宜锯材和优质木材生产和木材运输（包括通往适宜公共道路的连接）的土地上创建阔叶林。
- ‘原生苏格兰松’
创建或扩大原生松林优先生境（NVC）W18。
