About key messages

Key messages provide a descriptive index to studies we have found that test this intervention.

Studies are not directly comparable or of equal value. When making decisions based on this evidence, you should consider factors such as study size, study design, reported metrics and relevance of the study to your situation, rather than simply counting the number of studies that support a particular interpretation.

Supporting evidence from individual studies

  1. A 2011 systematic review (Smith et al. 2011) found that excluding predators using fences (see ‘Physically protect nests from predators using non-electric fencing’) or barriers around individual nests (‘Physically protect nests with individual exclosures/barriers’) significantly increased hatching success. Individual barriers appeared to be slightly (non-significantly) more effective than fences, but some studies found that they increased predation on adults (see ‘Can nest protection increase predation of adult and chick waders?’).
