Criteria

Question 1: Does species need conservation or recovery in England?
Response: Yes
Justification: Eng WeBS trends (25 yr -44%, 10 yr -44%). Seabirds Count -3% since S2K and HPAI impacts since then
Question 2: Does recovery/ conservation depend on species-specific actions?
Response: Yes
Justification: For non-breeding pop. Priority to address breeding population.
Question 3: At a landscape scale, would the species benefit from untargeted habitat management to increase habitat mosaics, structural diversity, or particular successional stages?
Response: No
Justification: priority to address breeding population
