Reduce nest predation by excluding predators from nests or nesting areas Bird Conservation

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?’).
