National Forest Inventory Woodland

Description: 
This Forestry Commission dataset 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, including areas of new planting, clearfell, windblow and restocked areas. The woodland map excludes all 'tarmac' roads, rivers and powerlines where the gap in the woodland is greater than 20 meters wide. Analysis of changes to the dataset overtime enables understanding of how the extent and types of woodland are changing in the Lake District and help to identify how policies and interventions are affecting this habitat. Data is quite detailed and is freely available. Use of the National Forest Inventory for monitoring would be low in terms of resources and time input.
Originator: 
Forestry Commission
Is this an existing or new approach to measuring landscape change?: 
Existing
Aspect of landscape: 
Spatial coverage: 
All woodland (both urban and rural, regardless of ownership) which 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 extend. Woodland less than 0.5 hectare in extent will not be described within the dataset but will be included in a separate sample survey of small woodland and tree features.
Geographical unit: 
Woodland
Frequency of measure: 
Annual
Establishment cost: 
Low (existing resources)
Ongoing operational cost: 
Low
Ongoing reporting cost: 
Low
Data source: 
The changes in the canopy cover have been identified on remote sensing imagery taken during spring/summer 2017 or colour aerial orthophotographic imagery available at the time of the assessment. Additionally, new planting information from grant schemes and the FE sub-compartment database for the financial year 2017/2018 have been added to the woodland map. The changes in the woodland boundaries use the Ordnance Survey MasterMap® (OSMM) as a reference where appropriated. OSMM is the most up to date large-scale digital map of GB providing a seamless database for 1:1250, 1:2500 and 1:10000 survey data.
