Provide ‘sacrificial’ grasslands to reduce the impact of wild geese on crops

2All six studies from the UK (including four replicated, controlled trials) found that managing grasslands for geese increased the number of geese using these areas. Four of these studies found geese were moving within the study sites. Assessment: unknown effectiveness — limited evidence (effectiveness 20 %; certainty 5 %).

3We have captured no evidence for the following interventions:

• Avoid use of lead shot
• Use alerts to reduce grey partridge by-catch during shoots

Evidence not assessed

Use scaring devices (e.g. gas guns) and other deterrents to reduce persecution of native species
