Provide artificial nesting sites for grebes
Overall effectiveness category Unknown effectiveness (limited evidence)
Number of studies: 1
Background information and definitions
Like divers/loons, grebes are highly specialised for swimming and diving and are therefore vulnerable on land. Providing artificial islands or floating rafts may increase both the number of birds nesting at a site, and their reproductive success.
Supporting evidence from individual studies
A 1992 review of the use of artificial islands and floating platforms in 17 wetland nature reserves across the UK (Burgess & Hirons 1992) found that great-crested grebes Podiceps cristatus and little grebes Tachybaptus ruficollis used well-vegetated islands and platforms at inland sites in the south of the UK. In addition, great-crested grebes used sparsely covered islands and platforms at inland sites, and well-vegetated ones at coastal sites. Neither species used either type of nesting site in Scotland. The review also examines island and platform use by divers, rails, ground-nesting seabirds, waders and wildfowl.Study and other actions tested
