What Impacts?
- The native Woodland Survey of Scotland
(NWSS) identified and surveyed all native, nearly native and ancient woods
- ver 0.5ha in size in Scotland, from
2006-12.
- Native woods were defined as those with
at least half the woodland canopy cover composed of native species.
Managing Impacts - Woodland 2 of 6
- Herbivore Impact score was based on an assessment of:
- ‘browsing rate’ for lead shoots, ‘browse line’, ‘browsing of basal and
epicormic shoots’, ‘bark stripping and fraying’, and ‘shrubs – preferentially browsed’. ‘grazed sward and ‘poached ground’.
- Information was later analysed to assign each polygon a herbivore impact
rating on a 4 point scale (Low, Medium, High, and Very High).
- The main herbivores thought responsible were recorded where known.
