Background information and definitions

Lagoons can form important feeding and overwintering grounds for wildfowl and waders, providing a rich supply of invertebrate food. However, they are often drained to provide farmland, or lost due to coastal management and development.

Study locations

Key messages

A before-and-after study in the UK found that large numbers of bird species used, and bred, in a newly-created lagoon.

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

A before-and-after study in Lincolnshire, England (Bradley & Allcorn 2006), found that a 15 ha saline lagoon created as part of a flood defence scheme in 2002 was subsequently used by 38 species of overwintering waterbird, at least ten of which bred.
