Grasshopper Warbler Welfare in UK Wetland and Scrub Habitats

Understanding the secretive grasshopper warbler and protecting its declining habitat.

Key Facts

Grasshopper warblers are heard rather than seen — their reeling song resembles a grasshopper
Require dense, tussocky vegetation with bare ground for foraging
Populations have declined significantly across much of England
Long-distance migrants to Sub-Saharan Africa — facing pressures throughout their range

Welfare Considerations

Grasshopper warbler welfare depends on dense tussock grassland and scrub with structural diversity. Loss of traditional wetland management and conversion of rough grassland to improved swards has removed key nesting habitat. Welfare-informed habitat management creates and maintains tussocky grass, rush pasture, and damp scrub through targeted grazing and water level management.

What You Can Do

Support wetland and grassland conservation organisations managing habitat for this species
Report grasshopper warbler singing males during June surveys to contribute to population monitoring
Advocate for rush pasture and tussock grassland retention in agri-environment scheme requirements
