Common snipe have declined significantly across Britain as drainage of upland bogs and lowland wet grasslands removes the soft wet ground essential for their feeding and nesting welfare.
Snipe have highly specific welfare requirements for soft, waterlogged ground that allows deep bill probing for earthworms and other invertebrates. In drained or compacted agricultural landscapes, snipe cannot feed effectively and must travel between increasingly distant wetland fragments, increasing energy expenditure and predation risk. Loss of upland blanket bogs through drainage removes both breeding and feeding habitat simultaneously. Bog restoration through drain blocking creates welfare-positive outcomes for snipe at relatively low cost.
