Overview of grasshopper warbler welfare, dense grassland habitat needs, and population decline.
Grasshopper warbler welfare depends on structurally diverse rough grassland and scrub habitats that have been reduced across the UK. The characteristic reeling song provides population monitoring opportunity during breeding season. Conservation requires agri-environment delivery of rough grassland with appropriate vegetation structure and connectivity. West African wintering conditions also affect UK breeding population welfare. Scrubby young plantation and rank grassland welfare management are priority actions.
