Texte intégral
Based on the collated evidence, what is the current assessment of the effectiveness of interventions for perennial (non-timber) crops?
Unknown effectiveness (limited evidence) | ● Maintain traditional orchards |
No evidence found (no assessment) | ● Manage short-rotation coppice to benefit wildlife (includes 8m rides) |
Unknown effectiveness (limited evidence)
Maintain traditional orchards
1A replicated, controlled site comparison from Germany found more plant species in mown orchards than grazed or abandoned ones, but found no effects on wasps or bees. Two replicated site comparisons from Germany and Switzerland found traditional orchards managed under agri-environment schemes either did not have more plant species than controls or offered no clear benefits to birds. Assessment: unknown effectiveness — limited evidence (effectiveness 10%; certainty 15%).
