Damage by some woodland mammals can have a significant impact on trees of all ages and on the wider woodland ecosystems by:
- Preventing tree establishment, healthy growth or good timber quality
- Preventing the development of a structurally diverse shrub layer
- Reducing the abundance of palatable plants such as bramble, bluebell, dog’s mercury and honeysuckle
- Increasing the abundance of grasses and unpalatable species such as bracken, rushes and ragwort
- Reducing the structural diversity of ground vegetation (a particular problem with close grazing by deer or rabbits).
This programme provides research into methods for:
- Reducing the impact of mammal damage on trees and woodland
- Reducing the impact of deer fences on sensitive species such as woodland grouse.
- Monitor, develop and improve techniques and materials for cost-effective protection of trees and woodlands from damage by deer, rabbits and voles
- Monitor, develop and improve techniques and materials to reduce the impact of forest fencing on capercaillie and black grouse
- Continue to develop novel techniques and provide advice on best practice to enable land managers to reduce damage to acceptable levels.
