Targeted grazing for the restoration of sub-alpine shrub-encroached grasslands
A field study in Val Troncea Natural Park, Italy, assessed whether concentrated cattle activity could reduce shrub cover and support the return of productive grassland vegetation.
Research summary
The study compared two targeted grazing practices over shrub-encroached ground and found that both reduced shrub cover, while temporary night camp areas produced the stronger overall vegetation response.
Context
The decline of agro-pastoral activity has allowed trees and shrubs to spread across former semi-natural, nutrient-rich grasslands in many European mountain regions. This changes vegetation structure and can reduce the amount and pastoral quality of accessible forage.
Approach
Researchers established temporary night camp areas and placed mineral mix supplements to focus cattle activity on encroached sites in Val Troncea Natural Park. Permanent transects were monitored from 2011 to 2015 to assess vegetation structure and forage pastoral value.
Four years after treatment, both practices were associated with lower shrub cover.
Grass and herb cover increased, together with the average height of the herbaceous vegetation.
Night camps favoured graminoids and higher-quality forage species while reducing low woody growth.
The strongest improvement in forage value occurred within the temporary night camp areas.
Interpretation
Within the conditions examined, concentrating cattle overnight was the more effective of the two pastoral practices. It offered a practical way to counter shrub encroachment while increasing herbage mass and forage quality in sub-alpine grasslands.
