National Forest Inventory Woodland Map 2019 (GB)
The National Forest Inventory (NFI) woodland map covers all forest and woodland area over 0.5 hectare with a minimum of 20% canopy cover, or the potential to achieve it, and a minimum width of 20 metres. This includes areas of new planting, clearfell, windblow and restock. The woodland map excludes all 'tarmac' roads and active railways, and forest roads, rivers and powerlines where the gap in the woodland is greater than 20 meters wide.
All woodland (both urban and rural), regardless of ownership, is 0.5 hectare or greater in extent, with the exception of Assumed woodland or Low density areas that can be 0.1 hectare or greater in extent. Also, in the case of woodland areas that cross the countries borders, the minimum size restriction does not apply if the overall area complies with the minimum size.
Woodland less than 0.5 hectare in extent, with the expectation of the areas above, will not be described within the dataset but will be included in a separate sample survey of small woodland and tree features.
The woodland map is updated on an annual basis and the changes in the woodland boundaries use the Ordnance Survey MasterMap® (OSMM) as a reference where appropriate.
The changes in the canopy cover have been identified on;
~ Sentinel 2 imagery taken during spring/summer 2018 or colour aerial orthophotographic imagery available at the time of the assessment;
~ New planting information for the financial year 2018/2019, from grant schemes and the sub-compartment database covering the estate of Forestry England, Forestry and Land Scotland and Natural Resources Wales;
~ Bluesky’s National Tree Map (NTM) dataset was used to revise woodland areas between 1 and 2 ha in England and Wales;
~ Woodland Carbon Code dataset was also used to revised areas of approved new planting outside the existing approved grant schemes.
Woodland areas, greater than 0.5 hectares, are classified as an interpreted forest type (IFT) from aerial photography and satellite imagery. Non-woodland areas, open areas greater than 0.5 hectare completely surrounded by woodland are described according to open area types.
IFT categories are Conifer, Broadleaved, Mixed mainly conifer, Mixed mainly broadleaved, Coppice, Coppice with standards, Shrub, Young trees, Felled, Ground prep, Cloud \ shadow, Uncertain, Low density, Assumed woodland, Failed, Windblow.
IOA categories are Open water, Grassland, Agricultural land, Urban, Road, River, Powerline, Quarry, Bare area, Windfarm, Other vegetation.
For further information regarding the interpreted forest types (IFT) and the interpreted open areas (IOA) please see NFI description of attributes available on http://www.forestresearch.gov.uk/

- Statement
-
The location and extent of all forests and woodlands (0.5 hectares and over) is stored and maintained as a digital map. The changes in the canopy cover are identified from:
• Sentinel 2 imagery taken during spring/summer 2018 or colour aerial orthophotographic imagery available at the time of the assessment;
• New planting information for the financial year 2018/2019, from grant schemes and the sub-compartment database covering the estate of Forestry England, Forestry and Land Scotland and Natural Resources Wales;
• Bluesky’s National Tree Map (NTM) dataset was used to revise woodland areas between 1 and 2 ha in England and Wales;
• Woodland Carbon Code dataset was also used to revised areas of approved new planting outside the existing approved grant schemes.
Ordnance Survey MasterMap® (OSMM) features have been used as a reference for capturing the woodland boundaries.
