The following protected areas data are used in the analysis:
Priority Habitats – good quality semi-improved grassland
The priority habitats are described here.
These codes are coordinated across England and Wales. They are used as the DN value when rasterising the data. England and Wales have been rasterised and merged into priority_habitats_england_and_wales.tif
Wales does not distinguish between ‘Lowland Fens’ and ‘Reedbeds’ and has them in the same category (10), whereas England distinguishes between the two ‘Lowland Fens’ (10) and ‘Reedbeds’ (37).

Special Protected Areas
SPAs are designated under the Wildlife & Countryside Act 1981 and Conservation Regulations 2010 to protect rare and vulnerable birds
Special Areas of Conservation
SACs are designated under the Conservation of Habitats and Species Regulations 2017 (see also the RSPB IBAs)
[Important Bird & Biodiversity Areas]
Ramsar Sites are designated under the Ramsar Convention for the protection of internationally important wetlands.
Sites of Special Scientific Interest
Biological SSSIs are areas of special interest “by reason of any of its flora, fauna, or geological or physiographic features”.
Persistent Non-vegetation / Urban Areas
Built up areas are obviously excluded from opportunity woodland. There are two sources of information for this exclusion zone:
National Nature Reserves
Local Nature Reserves
